Just to draw attention to the newly updated catalogue available to download online or order through the post for the measly fee of two first class stamps! (There is always a link to the catalogue in the panel top left of my web site.)
Impatiens oxyanthera Milo
As usual almost everything here is difficult or impossible to source elsewhere, and new things are added all the time.
I update the paper catalogue two or three times a year, and it has many more varieties than here on the blog so it's well worth checking regularly.
Hugueninia tanacetifolia suffruticosa
