Hear, Hear…lend me an ear

We always look forward to elephant ear evaluation day at JLBG, which was recently completed. Each year, Colocasia breeder, Dr. John Cho flies in from Hawaii to study and select from our field trials of his new hybrids. This year we were joined by Robert Bett, owner of the California-based plant marketing firm, PlantHaven, who

Bifid Rhodophiala

The genus rhodophiala is in a state of flux. Some taxonomists believe the genus actually doesn’t exist and should be merged with rain lilies, while others consider it a perfectly valid genus with 27 species. Oh, the joys of taxonomy. To most gardeners, the genus rhodophiala are simply dwarf hippeastrum (horticultural amaryllis), the most commonly

Crinum Time Again

Re-appropriating a line from the late Buck Owens, it’s crinum time again. Crinum lilies begin their flowering season in our climate around April 1 (frost permitting). Some bloom for a short number of weeks, while other rebloom for months. Depending on the genetics, some crinum hybrids start flowering in spring, some in summer, and others

Monroe’s Monkey Grass

Monroe had any idea what would become of his white-flowered monkey grass, that he selected as a seedling and subsequently introduced to the gardening world in 1957? In the 65 years that’s passed since it’s introduction, Liriope muscari ‘Monroe White’ is still the gold standard by which

Bald Head, but Sexually Active

If you’ve lived in the deep south…the land of palmetto palm trees, you know that they typically don’t flower until they have at least 5 feet of trunk. Of course, flowering can be sped up by a combination of precocious genes and good growing conditions. Those who have studied Sabal palmetto in the wild have

Pteris on the Terrace

We’ve long loved the fern genus, Pteris (pronounced terrace), but struggled for years to find any that were winter hardy here in Zone 7b. That changed with our 1996 Chinese expedition to Yunnan Province, and later a subsequent expedition by gardening friends to Sichuan Province. On both trips, high elevation collections of Pteris vittata were
