The late plantsman Alan Galloway was a prolific plant collector in Southeastern Asia, and one of the plants that has surprised us with its winter hardiness is the giant evergreen Solomon’s Seal, Disporopsis longifolia. In the wild, Alan and I encountered this throughout Thailand and Vietnam, but our tallest clone is one which Alan collected in Laos, and we christened Disporopsis longifolia ‘Alan’s Laosy Giant’. Our clump, which has been in the garden since 2007 has topped 5′ in height and is in full flower this week. Sadly, it has yet to produce a single offset.
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.
One of the gems from our 2012 botanizing trip to the Balkans, was a growable selection of Paris quadrifolia. For those who haven’t mastered Latin, quadrifolia means 4-leaves. All cultivated forms of this widespread European trillium relative had failed to thrive in our hot humid summers. Our collection from the Croatian town of Rude (I’m not making this up), has thrived, forming a lovely patch and even flowering. Hopefully, one day in the future, we’ll have enough to share.
In the plant world, plants that have no chance of selling, except to a tiny few crazed plant collectors, are called BIO plants, which stands for “of botanical interest only”. Coptis japonica var. dissecta fits the bill on all accounts. This fascinating Asian woodland perennial maintains a small evergreen rosette, topped in spring with tiny spikes of tiny fuzzy white flowers that age to these fascinating seed heads in the garden now.
Flowering this week is the fascinating Asarum speciosum, native to only three counties in central Alabama. In bloom, it resembles a mass of bloodshot eyes peeking out from beneath the skirt of anise-scented foliage.
The rare Dryopteris x australis is looking superb in the garden this week. This Southeast native, naturally-occurring hybrid will grow in sun or shade and in wet or average soils. Despite its deep southern roots, it’s fine outdoors in Zone 5a. 4′ tall..pretty amazing!
Few flowering plants are older than members of the genus chloranthus, which first originated between 22 and 150 million years ago, during a time that flowering plants were just evolving, and long before nurseries or garden centers came into existance. Chloranthus aren’t just interesting botanically, they also are unique textural plants for the spring woodland garden, where they are amazingly easy to grow. Here are two of our favorites in bloom this week…Chloranthus japonicus and Chloranthus sessiliflorus ‘Get Shorty’.
Variegated plants have part of the normal green portion of the plant leaf being replaced by white, cream, yellow, or occasionally other colors. How cool is that!
As a design element, variegated plants are often used as the center of attention or as a focal point in the landscape to lighten up a normally dark space.
Plants with bold variegation seem to scream for attention in the garden, hence their use as accent plants. As with all brightly variegated plants, they show off best when contrasted against a dark background. Whether planted against a mostly green hedge, or a larger backdrop of deciduous trees, some background is needed to properly display variegated trees, shrubs and perennials.
Epimediums have long been a staple of the woodland perennial garden, but it wasn’t until plantsmen like Darrell Probst (US) and Mikinori Ogisu (Japan) began discovering and sharing the amazing wealth of unknown Chinese fairy wing species that their popularity began to take off.
It wasn’t until 1998 that epimediums begin appearing in the Plant Delights catalog, because before that time, the available horticultural offerings just weren’t that impressive. Plants like Epimedium x youngianum ‘Niveum’ are just hard to get excited about…if you’ve got much of a horticultural pulse. Sadly, that’s still the most dominant choice at most garden retailers.
Another reason epimediums have been slow to become mainstream is the difficulty in getting good images. Because epimediums are so three-dimensional and prone to flutter in the wind, it takes quite an effort to take good images. Single flower closeups, which are much easier to take, always make me skeptical about how nice the entire plant will look in the garden.
When we were preparing to offer epimediums for the first time, we were faced with the decision of which of the three common names to use; fairy wings, barrenwort, and horny goat weed. Well, it doesn’t take much marketing savvy to choose from that list. That said, if we’d known that porn megastar Ron Jeremy would soon have his own line of epimedium tablets for male enhancement purposes, we might have reconsidered.
Once we became enamoured with fairy wings, we did as OCD people are prone to do, and built an entire research structure for the study, development, and trial of epimediums. We currently grow over 330 different epimedium taxa…some for study, some for conservation, and some which have enough garden value to share. It usually takes us about five years to fully evaluate a new epimedium seedling, comparing it to all other varieties on the market.
Since 2000, we’ve introduced over 27 of our own epimedium selections with more in the queue. Here are a few that we’ve already introduced that have proven to be excellent performers. We hope you’ve tried them all.
So, what’s next? Here’s a sneak peak of some of selections that have passed the final stages of in-ground trialing and are ready to head to container production trials. Our standards include good garden vigor, good floral showiness, and uniqueness from all other epimediums on the market. We like to think our standards are pretty high. We’d love to hear which of these future introductions below are your favorites.
