Ruellia malacosperma is providing a lovely pop of purple in front of the variegated gardenia. The fine-textured foliage in the foreground is provided by the rare Texas native, Hibiscus dasycalyx. When you’re planting in the garden, think of each planting as a photographic vignette, and you’ll be amazed what it will do for the visual appeal of the garden.
We’ve played around with growing cast iron plants from seed, curious if the white-tipped pattern of Aspidistra elatior ‘Asahi’ was heritable. Turns out that it is. Aspidistra ‘Blizzard’ is our seedling with well over half of the leaf being white. That makes it both beautiful, but insanely slow growing. The plant below has been in the ground for 5 years, planted as a two year old seedling.
Looking great in the summer garden is the stunning cast iron plant, Aspidistra elatior ‘Asahi’. This amazing woodland evergreen is a plant we can’t imagine gardening without. The leaf patterning is brightest as the new leaves emerge in June/July. Grown as a house plant, it needs to get some size before you will see the leaf patterns in containers. The Japanese name, ‘Asahi’ translates to “morning light”. Hardiness is Zone 7a-10b.
Below is a variegated sport of M. ‘Mission to Mars’. These have reached 5′ in width.
Mangave ‘Foxy Lady’ is a variegated sport of M. ‘Silver Fox’
The North American native Thuja plicata ‘4Ever’ is looking particularly stunning in the garden this summer. Of all the forms of Thuja plicata we’ve trialed, this is undoubtedly the brightest. Reportedly maturing at 12′ tall x 3.5′ tall, I’m left to wonder what they used the measure the size. Our 4 year old specimen is 5′ tall x 5′ wide. Based on the current growth rate, we’d expect 12′ tall x 12′ wide in 10 years, so if you’re looking at “forever”, I’d probably put these on 15-20′ centers.
Here’s a golden moment from JLBG this spring. The gold tree in the back is Salix ‘Golden Sunshine’. In the foreground is Juniperus conferta ‘All Gold’. The small tree in the center is Acer palmatum ‘Koto-no-ito’, and the purple foliage shrub is Physocarpus opulifolius ‘Seward’. Garden scenes can be tied together by repeating colors, even with different plants.
Looking lovely in the gardens today is the incredible Epimedium ‘Pink Champagne’. This 2007 Darrell Probst introduction still remains one of the finest fairy wing cultivars ever introduced. Our plant below is growing where it receives a couple of hours of mid-day sun. A mature clump will reach 2′ tall x 3′ wide. Winter hardiness is Zone 5a-8b.
When it comes to plants, we’re what you’d call a high risk, high reward garden. In other words, nothing ventured horticulturally, nothing gained. That was our thoughts last year when we planted our only plant of the rare variegated orchid, Cymbidium goeringii ‘Xueshanbiancao’ in the crevice garden, just months before our coldest winter in five years.
Not only did our baby sail through the winter, but it’s now sporting a flower, which is also variegated with a narrow creamy border. The soil mix in this section is 50% Permatill, 25% native sandy loam, and 25% compost. How cool is that!
Flowering in the garden now is the wonderful US native Pachysandra procumbens (Allegheny spurge). Native from Indiana south to the gulf coast, our selection, Pachysandra ‘Angola’ comes from the woods near that well-know Louisiana prison. This stunning evergreen, variegated, slow-spreading, woodland groundcover, is quite different from its better known and much faster spreading Asian cousin, Pachysandra terminalis. The flowers are also sweetly fragrant, what more could you want? Hardiness is Zone 5a-9b.
We’re several years into an experiment to see how well the epiphytic (grow mostly on trees) tongue ferns of the genus Pyrrosia fare in hanging, moss-lined baskets when left outdoors all year. This is our coldest winter to date since the test began, with a low of 11 degrees F. Here is a photo of one of those baskets taken today. They were not protected in any way during the cold. We have 17 clones on trial in this manner, and some do show a bit of foliar damage, while others are untouched. We think it’s quite amazing to have evergreen hanging baskets of live plants that can remain outdoors here in Zone 7b.
Platycladus orientalis ‘Van Hoey Smith’ is looking absolutely fabulous in our garden this winter. This fascinating selection of Oriental arborvitae, Platycladus orientalis was named after the late Dutch conifer guru, Dick van Hoey Smith (1921-2010), by an American nurseryman, who reportedly received these cuttings, unlabeled, from Dick. Some conifer folks think this is actually an old cultivar, Platycladus orientalis ‘Aureovariegata’. I understand this is not a good performer in climates with low humidity, but it sure likes it here in NC. Winter hardiness is Zone 5b-9b.
So, who is Van Hoey Smith? Born, James Richard Pennington van Hoey Smith, Dick’s family started the famed Trompenberg Arboretum in Holland, which Dick later ran from 1950 until he handed over the reins to his successor Gert Fortgens, in 1996. If you haven’t visited, I highly recommend a visit for any keen plant lover.
Dick was a founder of the International Dendrology Society, a membership society of the worlds keenest woody plant aficionados. He also wrote/photographed several reference books including Maples of the World, Conifers, and Rhododendron Portraits. He was awarded the worlds’ top horticultural prizes, including the Doorenbos Medal from the Dutch Dendrological Association and the Veitch Memorial Medal from the Royal Horticultural Society.
