Check out our Tioga Party

On of our obsessive plant friends, Glen Melcher, of Tioga, Lousiaiana, sent us several seedlings a few years ago, from his cross of Hibiscus paramutabilis x mutabilis. We made our final selection this fall, which we’ve christened Hibiscus ‘Tioga Party’. This 12′ tall x 12′ wide beast puts on quite a show, starting several weeks

To Breed or Not to Breed

We make crosses on our flowering agaves during the early summer, then in some cases, must wait until fall to see if we were successful. If we don’t get pods formed within a few weeks, we know that the particular cross was a failure, but in some cases, the cross forms pods, but there is

Iron Clad Hybrids

Up until a couple of years ago, we could find no literature detailing any hybrids in the cast iron plant genus, Aspidistra. With our extensive in-ground collection, we had begun noticing seedlings that were obvious hybrids, so we began first by confirming that both the flowers and foliage showed signs of being intermediate between both

Grasping Wags – a New Reveal

Trachycarpus x forceps is our assigned name for crosses between Trachycarpus fortunei and Trachycarpus princeps. While most Trachycarpus fortunei is winter hardy here in Zone 7b, the lovely Chinese/Tibetan border endemic, Trachycarpus princeps,

Amarine – a Manmade Gem

Looking great in the garden in November are our collection of x Amarines. These are a fascinating man-made group of hybrids between two South African genera of bulbs, Amaryllis belladonna and Nerine, first described in 1961. These grow their foliage in winter, which is a problem in climates as cold as ours. If the foliage

Stirring the Gene Pot

The first photo below is our hybrid century plant, Agave x ocareginae ‘Oh Victory’, from a cross we made in 2014, between Agave ocahui and Agave victoriae-reginae. The plants went in the ground in 2017. Of the eleven seedlings we selected and planted in the ground, only five have survived. Below you can see both
