Try as we might, we have been epic failures trying to grow the showy southwest native Zauschneria (now epilobium) in our garden, due to the combination of high humidity and torrential summer rainfalls. No matter where we tried them in the rock garden, they quickly expired. That was in the years BC…before crevice. Here is our plant of Zauschneria canum var. arizonica ‘Sky Island Orange’, a David Salman selection, planted in early 2018 and still thriving in our urbanite crevice garden. Not bad for a plant that doesn’t grow here.
The 7′ tall, and very floriferous Hedychium ‘Flaming Torch’ is looking quite stunning today in the garden. Although they are commonly called ginger lily, they are not a true lily (genus Lilium) or a true ginger plant (genus Zingiber). Hedychiums are prized for their summer and early fall floral shows atop bold-foliaged stalks. The inflorescences are quite exotic looking, resembling clusters of orchids. Slightly moist, rich garden soils and at least 1/2 day sun are best for these hardy tropical looking plants.
Gloxinias that I knew growing up were the typical florists Gloxinia my aunt and grandmother used to grow as house plants, with broad velvety leaves and large, brightly colored bell-shaped flowers.
Who knew you could grow Gloxinias in the garden? Well here comes Evita!! This selection of Gloxinia nematanthodes hails from 4,000′ elevation in Argentina (which introduces an increased level of cold hardiness for the temperate garden). Although it is late to emerge (June in NC), it makes an amazing 1′ x 4′ groundcover that is loaded with brilliant, 1″ orange-red blooms from August until frost. Your friends and hummingbirds will be thrilled!
Lobelia cardinalis is native to 41 out of the 50 states in North America. The cardinal flower is tolerant of many different soils from moist bogs to average garden soils, and is perfect for use in rain gardens. Cardinal flowers are also a magnet for hummingbirds and butterflies. Lobelia begins blooming in summer and will continue until fall with an array of flower and foliage colors to blend nicely in your garden, from the brilliant red flowers of the species, to the hot pink Monet Moment, or the burgundy foliage of Black Truffle.
You can order cardinal flowers online or visit us at our fall open house September 9-11 & 16-18 to see the cardinal flowers blooming in the garden and pick out that perfect plant for a spot in your garden.
Canna lilies are a great addition to your sunny summer garden or rain garden. Their large bold leaves come in a variety of colors and variegation patterns, and provide the perfect foil for brightly colored flowers from orange, to brilliant reds, rose to white. Cannas add color to the garden from late spring to fall and are an excellent attractant for butterflies and hummingbirds.
Here’s a recent photo from the garden of one of our favorite full sun, summer-flowering perennials, Sinningia ‘Arkansas Bells’. This amazing African violet relative thrives with cactus and agaves in our full sun rock garden, flowering from April until September, during which time, the hummingbirds have to wait their turn. We don’t currently offer this because not enough folks purchased it last time, which drives us a little nuts! It’s only winter hardy to 5 degrees F in the ground, but makes a superb container plant in colder zones. So, why do more people not buy this? Please convince us to propagate some more since it is so wonderful.
It’s hard to believe, but September is here and it’s time for our final Open Nursery and Garden for 2015. We hope you’ll join us to see all the gems that look great this time of year and stock up for the fall planting season with all the cool new plants from the fall catalog.
Plants, Plants, and More Plants
We also hope you’ve had time to enjoy the Fall Plant Delights Nursery catalog. We’re so excited by the new offerings, especially the clumping, heat-tolerant, mildew-resistant bee balms. These are a huge breeding breakthrough for anyone who likes monardas and attracting pollinators into the garden.
Other members of the same (Lamiaceae) family are also putting on quite a show now.Agastaches, first cousins to bee balm, are simply amazing in fall. In particular, Agastache ‘Peachie Keen’ and ‘Rosie Posie’ have been standouts in our trials and are still in full flower here. These are perfect for a sunny, well-drained spot in the garden where you can observe all the cool insects and hummingbirds which will visit.
While we’re talking members of the Lamiaceae family, we must mention the salvias. The Salvia greggii cultivars are putting on their fall show, as are many other fall-flowering species. Our favorite fall-flowering salvia has to be Salvia ‘Phyllis Fancy’. We moved a plant of this amazing giant into one of the new beds near the sales greenhouses, so people who don’t wander the gardens extensively will still get to enjoy it.
Final Open House for 2015…and More Plants
Did we mention we’re in the midst of our final Open Nursery and Garden for 2015? Friday through Sunday, September 11-13 and 18-20 (8-5 Friday and Saturday and 1-5 Sunday) are the final opportunities to visit until February 2016. We hope you’ll bring your want list from the fall catalog or just come and stroll the gardens.
There’s so much to see in the garden this time of year, including an array of ornamental grasses and a number of fall-flowering bulbs.Cyclamen hederifolium is flowering throughout the dry shade woodland garden, Also, an incredible array of shade-loving tricyrtis (toad lilies) are at their peak with their unique orchid-like flowers. For a bright spot in the fall shade garden, there are few plants as capable of adding as much sunshine as Boehmeria ‘Glow Light’…truly radiant.
We’ve had a great lycoris (surprise lily) season and a number of late-blooming crinum lilies are flowering nicely. Peak lycoris season at JLBG is August, but there are several cultivars which flower into September as you’ll see when you visit. Crinum lilies begin as early as May for us, but many re-flower through September, while others don’t start until fall. Their cousin, the mini-hippeastrum-like Rhodophiala bifida is also providing a bright spot of red throughout the garden now. Be sure to see what these genera have to offer for your fall garden.
Several more fascinating new plants from the fall catalog that are now looking great in the garden include Silene subciliata, Heteropterys glabra,Gloxinia ‘Little Red’, and Sedum ‘Dynomite’. Be sure to enjoy these stars out during open house…they’re hard to miss.
The dark blue-flowering leadworts (ceratostigma) are simply fantastic now as are the light blue-flowered caryopteris. Even buddleias (butterfly bushes) are showcasing their fall blue-lavender flowers. We think you can never have enough blues in the garden.
Other colors abound now including echinaceas (if they were cut back after their early flowering), dahlias, rudbeckia, verbena, hedychium, lobelia, ruellia, achimenes, and so much more. Bring your camera, bring your friends, and we’ll provide the great weather. We hope you’ll be able to visit!

News from PDN/JLBG
With our steady growth over the last couple of decades, we experienced an office space crunch, so to alleviate this, we were fortunate to recently purchase the adjacent 6-acre horse farm. While it’s sad to lose our wonderful neighbors, the Yde’s, we are excited to have more room. To get more office space, the nursery will be booting us out of our current home in the middle of the garden as soon as we build our downsized retirement home on the new property.
We are blessed to have acquired the services of one of America’s finest architects, Frank Harmon, of Raleigh, who, along with his team, have designed our new residence. (Tony was classmates with Frank’s late wife, Judy, at NC State…back in the day). The purchase will also allow us to re-configure the Open Nursery and Garden parking areas, which we believe you will enjoy. Be sure to follow the changes over the next year during each Open Nursery and Garden.
Anita will be leading her first class at the garden this fall, but it’s not about plants. Join Anita as she leads a sensory garden walk designed to awaken the senses and quiet the thinking mind. Anita will show you how experiencing the gardens through the senses will nourish the body, mind, and spirit. If your mind is open to new experiences, don’t miss this incredible opportunity to gain new insights from a truly amazing woman…yes, I’m prejudiced. You can learn more about Anita at http://AnitaAvent.com or read her wonderful Sensuous Gardening Blog at http://www.sensuousgardening.blogspot.com/. Seating for this class is very limited.
Remember to sign up for our other classes offered this fall:
- Josh Taylor’s Photography Class
- Tony’s Garden Walk
- The World of Soils

In news from the horticultural world, corporate giant, Ball Horticultural has purchased the 153-year-old Conard-Pyle Company from owner Steve Hutton, whose family has owned the business for the past 65 years. Even though you may not recognize the company name, Conard-Pyle is the manger/distributer of Knock-out roses…perhaps you’ve heard of them. They also introduced the “Blue Hollies”, the industry standard holly in the Northeast US.
Gardens of Germany
Our friend, landscape architect, Roland Oehme, son of the late landscape architect, Wolfgang Oehme is taking a plant trip to Germany and is accepting travel companions. This isn’t an organized tour per se, but a chance to visit gardens, nurseries, and study German garden design. The cost is $2500-$3000 including airfare. If you’re interested, you can email Roland at his company, Green Harmony Design, at email@example.com.
We were saddened this month to learn of the passing of plantsman Nick Nickou, MD, of Branford, CT, who passed away at the age of 94. In addition to being a physician for 40 years, Nick was a keen gardener and plant explorer (China, Russia, Greece, South Africa, Patagonia and more). We are fortunate to have a number of plants that Nick shared, growing in our garden, including his two most popular introductions, Athyrium ‘Branford Rambler’ and Athyrium ‘Branford Beauty’. What an amazing and wonderful life!
The nursery world lost a giant this month, with the passing of retired Monrovia Nursery President/CEO, Bruce Usrey. Bruce worked with Monrovia for over 45 years, starting in plant production and working his way up to CEO and, in his later years, Managing Director. Bruce oversaw much of the tremendous expansion of Monrovia during the 1980s through the 2000s, when Monrovia became a household brand. Bruce is survived by his wife, Susie, another 40-year Monrovia veteran.
Most everyone who grew houseplants from the 1970s through the 1990s has probably heard of Peters Fertilizer, which is a worldwide industry standard for quality and performance. Many of us vividly remember their famous blue fertilizer dye, which stained our hands and made those we subsequently dined with stare with horror.
We are sad to report that Peters founder, Robert (Bob) Peters just passed away at age 97. Peters rewrote the proverbial book on liquid fertilizer during the green industry heyday. Peters started his fertilizer company in 1947, but sold it in 1979 to the Grace Company, which later became Grace-Sierra. Grace-Sierra was subsequently gobbled up by Scotts in 1993. Disenchanted by the workings of a large corporation and their unequal promotion of their Miracle-Grow brand, Peters re-purchased the rights to their fertilizer in 2002, but not their original name. They subsequently started a new company, selling the old Peters fertilizer as Jack’s at www.jrpeters.com.

The amazing Manettia cordifolia has been in full flower for several weeks, and will continue for quite a while. As you can imagine, this is hummingbird central. Anita and I spent a good bit of time the other evening snapping photos of this amazing vine.
It’s been absolutely amazing to watch the swarm of honeybees, ants, and hummingbirds feeding on our giant 30′ tall flowering agave. Here’s an updated photo of the blessed event from yesterday. This weekend’s final summer open house is the last chance to see it in person.
Summer Open Nursery and Garden
Come see our 30 foot flowering agave at our final Summer Open Nursery and Garden Days this weekend. Visitors from around the country have been showing up to see our giant agave in flower, a 16-year-old specimen of Agave salmiana x Agave asperrima, with the first flowers opening right on cue for our summer open days. This is the tallest century plant we’ve ever flowered, with the tip of the spike topping out just a few inches below the 30′ tall mark. We’ve got our giant ladder perched nearby so Jeremy can make his daily pollinations, all while fighting off attacking hummingbirds.
We hope you’ll have time to walk around the garden while you’re here. The newly-opened, full sun Souto garden is looking fabulous, with so much color it’s almost overwhelming. Changes also abound throughout the older sections of the garden. Anita has suggested the removal of several formerly fenced and hedged areas to create more openness…we think you’ll enjoy these changes as much as we do.
Summer Nursery & Garden Days Final Weekend

Daylilies You’ll Notice — Royalty in the Summer Garden
If you visit during the summer, you’ll notice some rather impressive daylilies in the sunny areas. We’ve long enjoyed daylilies for their ability to add color to the summer garden and now have them showcased better than ever.
The prevailing daylily breeding trend since the 1970s has been to shrink the height of daylilies to appeal the masses. Obviously, this worked, since Hemerocallis ‘Stella D’Oro’ can be seen lining highway medians across the country. As horticultural contrarians, however, we enjoy taller daylilies, which we feel add much more visual interest to the garden. We don’t object to a few daylilies in the 3′ range, but rarely find the shorter varieties at the top of our favorites list, although some true dwarf rock garden daylilies would be fascinating.
Hemerocallis ‘Autumn Minaret’ is certainly the best known of the taller cultivars, topping out in our garden now at 6.5′ tall…yes, you read that correctly. This 1951 late season introduction was hybridized from one of the taller natural species, Hemerocallis altissima, which is actually a very small-growing plant that just happens to have a 5′ tall flower spike.
Hemerocallis ‘Purity’ is another summer-flowering favorite. The well-branched 5′ tall flower spikes hold hundreds of yellow-orange flowers over a very long time. We can’t imagine a summer garden without this gem. While we typically don’t rave about many daylilies that flower below 3′, there are a few noticeable exceptions. One that we continually tout as one of the best is Hemerocallis ‘Black Eyed Susan’. Without question, this amazing plant is one of the most floriferous and stunning daylilies we grow. Although it only manages 32″ in height, its show power in the garden is truly hard to match.
We’ve got many more of the taller daylilies in our trials, and have even moved a bit of pollen around this summer between some of the taller varieties, so we hope you find these “off the bell curve” daylilies worth including in your own garden.
Black Bamboo Death – The End is Nigh
The bamboo world has been rocked over the last few years as most of the black bamboo has begun its flowering cycle. While flowering is good in most plants, such is not the case with bamboo since, like agaves, it dies after flowering. Like century plants, a bamboo plant also takes about 100 years to flower but unlike agaves, bamboo offsets don’t survive. Since most bamboo is grown from divisions, when a particular clone flowers, it flowers everywhere around the world within a certain time window, influenced slightly by growing conditions.
Black bamboo began flowering worldwide in 2008, with many in the US starting only in the last year. Bamboo flowers are brown and insignificant, so most folks won’t even notice until the plant begins a steady decline. The sad part is that everyone’s black bamboo will die, but the up side is that more plants will be grown from seed and the new generation crop will have another 100-year lifespan. Also, all those folks who were lied to by retailers who told them black bamboo clumped will have their problem resolved. The take home lesson is that if you’re buying the running black bamboo (Phyllostachys nigra), be sure to ask if it’s a new generation plant from seed or the clone which is currently flowering.
Yucca Birth Records Confusion — Who’s Your Daddy?
For many years we’ve had a fascination with yuccas and have long been convinced that the taxonomy of the Southeast native species was a mess. Reading several recent DNA papers along with some older works from the early 1900s, we realized that most of what is labeled Yucca filamentosa is actually Yucca flaccida…a completely different species.
We’re in the process of updating all of our names on the website and apologize in advance for the confusion. All of the variegated cultivars of Yucca filamentosa, except for the cultivar ‘Variegata’, are actually selections of Yucca flaccida.
Yucca filamentosa, however, is a real plant. The real plant is what is known in the trade as the coastal boat-tipped yucca. We are currently propagating some true Yucca filamentosa for inclusion in a future catalog. If you vacation along the East Coast from NC south to Florida, the small yucca you see on the dunes is Yucca filamentosa.
Also growing on the southeast coastal dunes are two other species, Yucca aloifolia and Yucca gloriosa. It has long been theorized that Yucca gloriosa might represent a natural hybrid between Yucca aloifolia and Yucca filamentosa and, sure enough, the new DNA work confirms that theory. Consequently, the name should be written correctly as Yucca x gloriosa. Now it makes sense that when we were studying yuccas last year on the NC dunes, many plants seemed to be intermediates between the three parent species. We guess our eyes were not deceiving us after all. Two papers on the subject were shared by Larry Hatch of Cultivar.org and are found below if you are scientifically nerdy enough to care.
- Homoploid hybrid origin of Yucca gloriosa: intersectional hybrid speciation in Yucca
- Ecology And Evolution Of Southeastern United States Yucca Species
On our many Southeast US botanizing trips we discovered other natural hybrids along with another new southeastern native yucca species that seems to have never been named. We will be working to get it described and published in the near future…an exciting time for those of us who love yuccas.
Perennial Plant Registrations
Our friend Larry Hatch is looking to fill a gap in the registration of new perennial varieties. There is supposed to be a system in place for anyone who wants to officially register, for posterity purposes, any new perennial that they name and introduce. While some genera of plants like iris, daylilies, and hostas have a dedicated registrar and a functioning system, most genera of plants either don’t have a registrar or the system is too cumbersome. The New Ornamentals Society is working to streamline the process with a new no-cost registration system. We encourage you to give it a try here.
Fern Hardiness Oops
In our trials from this winter, it has become obvious that one of the ferns we offer isn’t nearly as hardy as our liner supplier had indicated. We lost all plantings of Dryopteris labordei ‘Golden Mist’ at 9 degrees F this winter, which is a far cry from its purported Zone 5 hardiness. The problem stems from a taxonomic confusion. Dryopteris labordei is considered a synonym of Dryopteris indusiata, the latter of which is a Zone 5 plant. Obviously, the two plants are not the same. While it’s still a great fern, we are shifting its winter hardiness to Zone 8a-9b. If you purchased this based on our previous hardiness listing, just drop us a note and we’ll add a credit to your account or issue a refund. Please accept our apologies for this incorrect information.
Last month saw the passing of one of the giants of the waterlily world, Patrick Nutt, 85, longtime curator of Aquatic Plants at Longwood Gardens. Pat was revered throughout the water lily world for his encyclopedic knowledge and as a water lily breeder, promoter, and educator. Pat will be best remembered as the breeder of the internationally-renowned giant water lily Longwood Victoria, which most summer visitors to Longwood have no doubt gazed on in amazement. Pat began his career at Longwood Gardens in 1957 and remained there for the next 38 years, until his retirement in 1995. Even after his retirement, he continued to be a regular at Longwood Gardens while also traveling around the world, collecting and researching water lilies. Our condolences go out to Pat’s family and friends…life well lived!
