Sue, I first ran across Geraniaceae and Hobbs three years ago, and was so relieved to see some specialty pelargoniums nurseries around!
Cooks nursery closed many years ago, Shady Hills appears to be selling
mainly collections now? They used to have a printed catalog with hundreds of varieties. Logees has also changed, they still do mail order,
but don't have the extensive catalog they used to have.
It is really hard to find the older varieties anymore. I've grown the Rosebud and tulip varieties since the seventies, but, like the fancy leaf, I can't find them every year.
I just wanted to share the info, so future aficionados would know where to look!
