Artist’s Palette in Winter

Asarum hypogynum ‘Artist’s Palette’ is in full flower here at JLBG in late January. Despite being first published in 1915, this little-known species is very poorly represented in ex-situ plant collections worldwide. Our clone is a division from a wild plant we brought back from our 2008 botanical expedition to Taiwan. The foliage on this

Laosy Mytilaria

Okay…everyone raise your hand if you’ve grown Mytilaria laosensis. This odd monotypic genus, native from Southern China to Laos, is first cousin to the also virtually unknown genus Exbucklandia, both in the Witch Hazel family, Hamamelidaceae . Since we’ve had our Exbucklandia in the ground since 1997, we though it was worth trying its cousin. Our Mytilaria

Meet Urophysa

Unless you’re a serious plant nerd, you’ve probably never heard of the plant genus, Urophysa. This small genus of only two species in the clematis family (Ranunculaceae) is only found growing in Karst cliff crevices in a few limited provinces of South Central China. In other words, they are quite rare. Urophysa henryi was originally

A New Ironwood earns its mettle

It’s far more common for new perennials to be discovered than new trees…it’s a size thing. Botanists were excited in 1960, when Chinese professor H.T. Chang published a new small tree that he thought to be a witch hazel, named Hamamelis subaequalis. The original Jiangsu Province collection actually dated to 1935, but it took 25

Tarahumara Oak

One of our prize plants in the garden is the Tarahumara Oak, Quercus tarahumara. This truly odd oak is native to Northern Mexico, where it resides in the Sierra Madre Occidental Mountain range in the Mexican states of Chihuahua, Sonora, Durango, and Sinaloa. In cultivation, Quercus tarahumara is extremely rare and of high conservation value. It seems that

My Summer Vacation trip to Lambou Field, Florida

Back in the early 2000s, I printed out every exchange from the International Bulb Society email list that discussed the bulb genus, hymenocallis (spider lilies). Most conversations originated with Victor Lambou, who was obviously an authority on the genus. It’s now been years since the Bulb Society went defunct and I had lost track of

Celebrating Ferners

One of the fabulous ferns in our garden during the summer months is the sun-tolerant Dennstaedtia hirsuta ‘Sohuksan’. This fabulous specimen came to the US from a 1985 collection from Sohuksan Island, South Korea, where it was discovered by a team of intrepid plant explorers that included horticultural legends as Barry Yinger, the late Ted

Alan’s Laosy Giant

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
