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.
Every year around July 4, we celebrate with our own horticultural fireworks show as the South African Scadoxus multiflorus ssp. katherine bursts into flower. Here are our plants at JLBG this week. This amazing bulb requires light shade to grow and thrive. Anyone whose woodland gardens suffers from the summer doldrums, would do well to include Katherine. Hardiness Zone 7b-10.
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.
We just love the East Coast native Chamaelirium luteum…aka: fairy wands. The male forms have the largest, most showy flowers, as seen here at JLBG this week. A lover of average/moist shade, it is long been used medicinally for female reproductive issues.
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’s hard to imagine a more spotted hardy plant than Arum x diotalicum ‘Chui’. Shared with us by UK plantsman John Grimshaw, this hybrid of Arum italicum and Arum dioscoridis shares the best traits of both species…the leaf markings of Arum italicum and the floral (spathe) staining of Arum dioscoridis. We hope to have enough to share in a couple of years.
