There are a number of very exciting new ajugas to hit the market in the last few years, but one of our favorites has a longer history. Ajuga reptans ‘Planet Zork’, which we first acquired in 2004, is a non-flowering, crinkled-leaf sport of Ajuga ‘Burgundy Glow’. It was brought to the US from Japan, and later named and introduced here by plantsman Barry Yinger. We first grew Ajuga ‘Planet Zork’ in light shade, but it really showed its true colors when we transplanted it into full sun and moist soils. It’s parent, Ajuga ‘Burgundy Glow’ is ungrowable in our climate, rotting at the sign of rain during our hot, humid summers. Unlike many ajugas, this is a tight clumper that doesn’t seed around…an ideal groundcover.
Just caught this perfectly posed Asarum splendens in flower on a recent photographing foray in the garden.
Ok, the spelling of “Susanna” is slightly different, but don’t let that deter you from growing one of the greatest groundcover clematis that we’ve ever grown. Yes, that’s right…no mailbox post or staking required. We’ve been growing this amazing, compact clematis as a groundcover for years and it is truly superb. Here it is in the garden this spring, but it will also continue to flower into summer. What’s not to love about Cezanne!
We’re always on the look out for great skirts in the garden. Skirt is the garden design term we use for groundcovers, which reduce the need for mulch, while still keeping with the textural integrity of the garden design. Here are a few images of plants that we consider great skirts.
We love this US native groundcover. The foliage is great and the flowers in very early spring are superb. At our home, we used it as a skirt for Acer palmatum ‘Orangeola’.
One of the top ajugas ever introduced because it doesn’t spread quickly or reseed. Very durable, but truly thrives in moist, compost rich soil. Here it is in flower this spring.
Another of the absolutely finest ajugas we grow. Ajuga ‘Planet Zork’ is a crinkled leaf sport of Ajuga ‘Burgundy Glow’, which is a miserable performer in our climate, but this sport is indestructible. It’s so mutated that we’ve never seen a flower, but who cares.
In our climate, Nepeta ‘Purple Haze’ is one of the best performing catmints, and one that is quite unique from others in the trade. We cut it back after flowering and it starts over and flowers again.
Our sales of this amazing PDN/JLBG selection of the US native fine-leaf mountain mint (Pycnanthenum tenuifolium) weren’t nearly what we’d hoped, so we planted the unsold plants out along the road in front of our home, here providing a nice textural contrast to another great US native plant, Juniperus horizontalis ‘Wiltonii’. We’ve made several selections of mountain mint over the years, but this is truly the star. We sure wish more people had tried this amazing plant.
Another native that simply didn’t sell the way it should is the iris relative, Sisyrinchium ‘Suwanee’. This is unquestionably the best blue-eyed grass ever!!! Found native in north Florida, it’s solid winter hardy in at least zone 6 and never reseeds like the native Sisyrinchium angustifolium. We believe this represents an un-named species, that’s in full flower here now if you drive by the nursery and see the mass of unsold plants we planted in our roadside ditch.

There are lots of different gingers to keep straight, starting with a memorable one that was a part of the band of misfits stranded on Gilligan’s Island. Horticulturally speaking, however, ginger refers both to a group of plants in the Zingiberaceae and Aristolochiaceae (birthwort) families. Hardy members of the Zingiber family are plants who mostly flower in the heat of summer, while the wild gingers (asarum) of the birthwort family tend to be mostly winter/spring flowering.
So, while it’s late winter/early spring, let’s focus of the woodland perennial genus asarum, of which we currently grow 86 of the known 177 asarum species/subspecies. In late winter/early spring, we like to remove any of the winter damaged evergreen leaves, which makes the floral show so much more visible. Few people take time to bend down and observe their amazing flowers, so below are some of floral photos we took this spring. View our full photo gallery here.
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!
The amazing Balkan native Genista saxitalis is in full flower today. This amazing groundcover has been brightening our rock garden for a couple of weeks. Genista is easy to grow with plenty of sun…hardiness is Zone 4a-8b.
Mazus reptans is looking particularly fabulous in the garden today…that’s a lot of flowers! Part sun and average moisture is best.
