The lovely native witch hazel, Hamamelis virginiana ‘Little Prospect‘ with its variegated foliage, looks amazing even when it isn’t in flower. The leaves show no foliar burn in full sun and it is just as beautiful in part shade. Hardiness Zone: 3a to 8b.
Even when the sun isn’t out, the golden willow, Salix sachalinensis ‘Golden Sunshine’ provides a bright spot in the garden. We love this amazing tree. I see quite a few sources who list this on-line as maturing at 18′ tall x 7′ wide. Well, that’s not quite accurate. The five year old specimen pictured below is now 25′ tall x 25′ wide. Growth is much faster in moist, rich soils, but it seems someone needs to trade in their tape measure.
A couple of our favorite native redbud selections looking exceptional after flowering today…Cercis canadensis ‘Flame Thrower’ and ‘Golden Falls’…both from the breeding work of NCSU plant breeder, Dennis Werner.
Last week we had a few rainy days, which resulted in some amazing patches of Dog Vomit fungus (Fuligo septica) on mulched areas in the garden. I remember back to my Master Gardener days, when you could always expect early spring phone calls from frantic gardeners looking for something to spray to rid their garden of this terror. The reality is that it causes no ill effects in your garden.
Dog vomit fungus, which has a worldwide distribution, was first named back in 1727, so it’s been around a lot longer than most of us. Why can’t we learn to embrace this amazing natural phenomenon? Other than not appealing to folks who were raised as germaphobes, this is one of many amazing shows that nature provides.
Not only does dog vomit fungus not bother your plants, it’s not actually a fungus. It belongs to a group of saprophytic slime molds, meaning it feeds on decaying organic matter. If the common name turns you off, you can use the newer PC name, Scrambled Egg slime mold. Within a couple of days, the color of the fruiting bodies will fade to brown and it will fade away, but isn’t it cool while in fruit!
Here are images of three of the “next generation” ajuga cultivars, all selections of the Italian Ajuga tenorii. These in-ground photos were all taken at JLBG on April 1. These new ajugas don’t spread wildly or seed around like many of the older, more commonly grown offerings. We think they are pretty darn amazing! The top photo of Ajuga ‘Blueberry Muffin’ represents several plants, planted on 1′ centers. The second image is a single plant of Ajuga ‘Cordial Canary’, and the third is a single plant of Ajuga ‘Petite Parakeet’. These are actually non-staged images, unlike the highly staged, completely unrealistic, manufactured photos you often see in the Dutch-centric catalogs. Hardy from zone 4a to 9b.
This winter has been an amazing one at JLBG for the mid-winter flowering, evergreen magnolias. Formerly known as Michelia, there are several species from warm temperature Asian climates, which flower in the mid-winter. The plant in the top photo is our oldest specimen of Magnolia platypetala, and below is Magnolia macclurei…both planted in 1999, and in full flower in January. Obviously, we will loose open flowers if winter night temperatures drop too far below freezing, but the remainder of the flower buds usually open shortly after temperatures warm.
Also, the bright gold shrub in the first image is the original plant of our introduction, Illicium parviflorum ‘Florida Sunshine’…the plant from which all plants in the world were propagated. To the lower right is the Mediterranean native, Phlomis fruticosa ‘Miss Grace’. All in all, a lovely winter garden combination.
I remember first meeting the golden foliaged Leyland cypress back in the early 1980s at the JC Raulston Arboretum, and falling in love. Despite eventually removing almost all of our other cultivars of Leyland cypress from the garden due to size issues, we still treasure this gem. For us, x Cuprocyparis leylandii ‘Golconda’, which was discovered in the UK in 1972 as a branch sport, has been a wonderfully slow grower in our climate….4′ tall in 25 years. We understand it grows much faster in climates with cool summer nights, but we’re thrilled ours is slow enough to stay garden-sized.
I can’t speak to the truth that blondes have more fun, but on behalf of gardeners who grow blondes (gold leaf plants), we certainly have more fun when they’re around. One of our horticultural holy grails has always been a gold leaf elderberry we can actually grow. The horticultural market is dominated by northern cold climate selections of colored-leaf elderberries, which refuse to survive our hot, humid summers.
I can’t tell you how excited we were a couple of years ago to learn of a Keith Mearns discovery of a wild elderberry near Columbia, SC with beautiful golden foliage, Sambucus canadensis ‘Blonde Envy’. Although it took us a while to track one down (Keith says that less than a dozen exist in the world currently), it is now performing beautifully in a prize spot at JLBG. We’ve turned our Plant Delights propagators loose in the hope we can have enough to share in the 2023 Plant Delights spring catalog.
Just prior to the pandemic, we were plant collecting in UK nurseries, and made a stop at the always amazing Cotswold Garden Flowers. Founder Bob Brown’s son, Edmund, had taken up elderberry breeding, and now held the National Sambucus collection. We were able to bring back a couple of his complex hybrid introductions to trial, and to our shock, both are thriving in our summers. Here is a photo of our 2 year-old clump of Sambucus ‘Chocolate Marzipan’ in the garden. Finally, sambucus envy will be over for southern gardeners.
Stachyurus chinensis ‘Golden Joy’ is looking fabulous in our garden. This new gold-leaf sport of Stachyurus ‘Joy Forever’, discovered by plantsman Ron Rabidou, has been a wonderfully bright spot in the woodland garden at JLBG
Looking and tasting great in the garden now is Origanum ‘Drops of Jupiter’. This amazing creation combines the taste of culinary oregano with oreganos which are grown solely for flowers…the ultimate edimental and a superb plant for pollinators to indulge.
Arundo donax ‘Golden Chains’ is looking quite nice in the garden this month. We love this selection of the giant ornamental grass that’s used for making reeds for wind instruments. Arundo ‘Gold Chains’ is much less vigorous than the the typical species, and much easier to fit into smaller gardens. Here’ we’re growing it as a marginal aquatic, where it thrives as well as it does in typical to dry garden soils.
One of our treasured finds from a recent botanizing trip in East Texas with plantsmen Adam Black and Wade Roitsch (Yucca Do), was a gold-foliaged Vaccinium arboreum (farkleberry). The parent plant was 30-40′ tall, but there were plenty of root suckers from a recent road grading. This could turn out to be a wonderfully exciting new native edimental.
The foliage of Amorphophallus konjac ‘Gordon’s Gold’ is truly superb in the gardens, looking like a forest of small golden palm trees. This is a great discovery from California plantsman, Dave Gordon.
This year, one of our plants had a leaf chimera mutation so that half of the leaf mutated to green, while the other half remained yellow. Most likely, this is a one year occurence.
We’re trialing quite a few of the new colored-foliage, non-invasive ajugas, and are quite excited so far. Here is one of several that we really like, Ajuga ‘Parrot Paradise’ in the garden. These ajugas open up a wealth of color combination possibilities for garden designers. Hopefully, you’ll see this gracing a Plant Delights catalog in a few months.
