We are thrilled at the performance of the little-known banana, Musa nagesium var. hongii. Our plants are from the recently discovered population in Northeast India, which is a good jaunt from the formerly known populations in Yunnan, China. These sailed through our cold winter, and have exploded in growth during our hot summer. We love the chalky stems, like its close relative, M. cheesmanii. Hopefully, we’ll be able to share these one day. Hardiness Zone 7b-10b.
Looking great in the garden in late summer is the little known love lily, Amorphophallus kachinensis. This southeast Asian species has now reached 7′ tall in the garden. Our earlier collections from Thailand were not winter hardy here, but this Peter Zale collection from Myanmar has thrived.
Flowering well in the late summer at JLBG is the florally magnificent banana, Musa ornata. Native to Myanmar, Northern India, and surrounding regions, it isn’t typically winter hardy in Zone 7b. This is Hayes Jackson’s selection, Musa ornata ‘Anniston’, which sailed through last winters 11 degrees F.
Looking great in mid August is Hedychium spicatum. This is a ginger lily species we saw throughout our late 1990s travels in Yunnan, China. Pictured below are our 3 year old seed-grown specimen, which has already become a massive 5′ tall x 10′ wide. The flower is much smaller than some of the more showy species of hedychium, but the overall garden impact is quite grand. Hardiness is Zone 7b-10 (guessing).
Many gardeners grow hardy aroids in their garden, ranging from the tiny arisarum to the giant amorphophallus, but few folks have tried members of the genus, Taccarum (tacky-arum). Taccarum is a small genus of only six species, all native to South America. As a nice addition, the flowers have no detectable fragrance.
In our trials, the star of the genus is Taccarum caudatum, a native to Bolivia, Peru, and Northern Brazil. From that region, there should be little possibility of winter hardiness here in Zone 7b, yet after more than a decade in the ground, they don’t just survive—they multiply and thrive.
In most locations we’ve planted them, they top out at 3′ tall, but several clumps we planted at the base of a large pine have now reached 6′ in height. We’ve named the hardy clone we grow, Taccarum caudatum ‘Eruption’.
Back in the early 2000s, we grew the spiral ginger, Costus speciosus for many years, before finally loosing it in a very cold winter, but its potential hardiness has always fascinated us. In 2013, Georgia plantsman Ozzie Johnson collected a specimen near the border of North Vietnam and Southern China at 3,900′ elevation. Below is Ozzie’s collection this week at JLBG, after our recent winter of 11 degrees F. The same plant, growing in Atlanta, survived 5 degrees F this winter without protection, so I think we can safely say we have a Zone 7b hardy form. This exceptional clone has been named Costus speciosus ‘Wizard of Oz’. It will take a few years to build up stock, but we’ll get this one ready as fast as possible.
I wish I could count how many times we’ve been told, “That won’t grow in your climate.”. Our contrarian streak has led us down many interesting paths, with quite a number of surprising results.
The most recent is Chrysophyllum oliviforme. Over a year ago, we planted seed grown plants, native to the recently hurricane-ravaged Sanibel Island, Florida. This species is native to Southern Florida, the Bahamas, the Greater Antilles, and Belize. With that distribution, it should have no chance in our winters, but, despite die back during last winter’s low of 16F, it returned, and is now approaching 4′ in height. I should add that our plant was planted on a very exposed site, with no protection.
Is it going to be a long-term plant….probably not, but there is obviously more winter hardiness than most informational sites would lead us to believe. I should add that we planted two seedling, and the other one planted nearby, succumbed to the winter temperatures. If you never take risks, you’ll rarely get to experience the joy of amazing surprises like these.
In flower this week is the amazing ginger lily, Hedychium ‘Flaming Torch’…our 1999 introduction, with its’ fragrant peachy flowers is still looking great! This is another of those plants that never sold particularly well, so we haven’t offered it since 2016. Winter hardiness is Zone 7b and warmer.
We’re always on the search for new bananas that will be winter hardy without protection in our Zone 7b winters, and two that have looked great so far are the South Asian native Musa balbisiana (Northeast India to South China) and the Northeast Indian native Musa nagensium var. hongii. If these continue to thrive, we will propagate these so we can share.
I’m always amazed that so many people don’t realize that turmeric (Curcuma longa) is an amazing garden perennial. We’ve had our plants in the garden for nearly 30 years. This week, the flowers of this delightful ginger lily from Southern India emerge, looking like fancy pink pine cones. Curcuma longa is very easy to grow, as long as the soil is reasonably well-drained. Just mark the planting spot, since it usually doesn’t break ground before June. Hardiness is Zone 7b-10.
Edgeworthia chrysantha ‘Snow Cream’ is a 2000 Juniper Level Botanic Garden/Plant Delights introduction that has proven to be one of our most popular introductions. We made the original selection from a group of seed-grown plants, imported from China by Canada’s Piroche Plants in the late 1990s. We were drawn to this seedling because of the particularly large flowers, and large leaves that reminded us of a plumeria. Let me be clear that all Edgeworthia chrysantha seedlings are nice, but there is certainly a significant difference between flower and leaf sizes of seed-grown plants.
Below are photos from our winter open nursery and garden days this year, where our garden specimens never cease to amaze visitors with both its sweetly scented flowers and amazing floral show. Sadly, no matter how many we propagate, it never seems to be enough to meet the demand. A more open site results in a much better floral show. Hardiness is Zone 7a – 10b.
Due to having three consecutive mild winters, with no temperatures below 20 degrees F, we’ve actually been able to get a trunk on our Washingtonia filifera palm. Typically not hardy in our climate, our plant was grown from seed collected from a wild population in Arizona that had experienced 10 degrees F. We’ll see what this winter has in store.
We love plant mysteries, and Sabal ‘Blackburniana’ fits the bill nicely. This pass-along seed strain has been considered by some to be an old hybrid of Sabal minor, while others consider it to be synonymous with Sabal palmetto, yet others consider it to be Sabal domingensis. Whatever it is, our plant is looking quite good in the garden. After growing it, unscathed, since 2008, we finally decided to propagate some for the upcoming Plant Delights catalog. If you know any more historical background about this curiosity, please share.
Here’s a recent image of the amazing Colocasia esculenta ‘Maui Sunrise’, still looking great in late October! Moist, rich soils and full sun are the key for your plants to look this spectacular! Winter hardiness is Zone 7b and warmer.
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.
Here’s another oddity in the fabulous ginger genus, hedychium. First, Hedychium ellipticum requires shade, compared to most hedychiums that need sun to flower. Also, Hedychium ellipticum has pendant stalks, compared to the rigidly upright stalks of most more commonly grown ginger lilies. We love the elegant flower heads that adorn the garden in late July/early August. This photo is from the gardens at JLBG last week. Hardiness is Zone 7b south. Sadly, this is always a poor seller when offered by Plant Delights…perhaps people just need to see this in person to appreciate its exquisite beauty.
Don’t let the name fool you, Hymenocallis caribaea ‘Tropical Giant’, as this North American native spider lily (Northern Mexico) has been hardy in our garden (zone 7b) without any protection since 2000. It’s flowering season has begun here at JLBG. Unlike some hymenocallis which require moist soils, this one will grow darn near anywhere. The new flowers open each evening, releasing a sweet fragrance that attracts night-pollinating moths.
Flowering at our exit drive this week is the beautiful Canna ‘Red Futurity’…a superb purple-foliaged canna lily. Learn more about growing canna lilies in your garden.
Late June is when the amazing hidden cone gingers (curcuma) begin to explode here at JLBG. Here is our clump of Curcuma ‘Pink Wonder’ this week emerging from what looked like a bare patch of ground in the woodland garden. After the flowers finish, the red-striped foliage explodes to 6-7′ tall.
Colocasias are a genus that can bring a taste of the tropics to your backyard garden. Colocasia ‘Thailand Giant’ is a huge strain of the giant elephant ear that can reach 9′ tall in the wild, and certainly makes its presence known in the garden. Can you say WOW factor! Each glaucous grey-green leaf is up to 5′ long and 4′ wide. It also produces abundant 8″ flowers with white spathes from summer into fall. Learn how to grow elephant ears here.
So if you’re looking for a tropical escape and want to make a bold statement in your garden, or just want to impress your friends and neighbors, get your very own Giant today!
