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.
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.
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.
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’.
It was a real thrill last week to visit a population of Cypripedium kentuckiense (Kentucky Ladyslipper Orchid) in Texas with native plant guru, Adam Black. Adam has made numerous trips to this and other nearby sites, carefully pollinating the orchids to ensure seed set and enhance reproduction. While we’ve offered this species as seed-grown plants (8 years from seed to flower) for years, this was my first chance to actually study them in the wild. Cypripedium kentuckiense is one of the easiest ladyslipper orchids to cultivate, thriving in a wide variety of woodland conditions. Here, they were growing just above a seasonally flooded stream in very sandy soils.
Although some may have unpleasant memories of Wuhan after a year of pandemic conditions, let’s not forget that many incredible joys come from the same town. We are delighted to share the floral show of Iris japonica ‘Wuhan Angel’ this week…a plant originally shared by gardening friend Hayes Jackson, from his trip to Wuhan, China years earlier. This makes a superb, vigorous woodland groundcover in Zone 7b and warmer.
One of our garden finds from 2013 is this lovely pewter colored toothwort, that we believe to be a hybrid of two southeast US native species, Dentaria diphylla x heterophylla. If stock building up continues well this spring, we’ll be able to finally share next January. It’s hard to capture the color well in a photo, but we think this is a woodland garden treasure.
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.
