I like to grow South African plants and tried this one. (zone 9) However the "foxglove" digitalis purpurea ( too) hybrid planted with them are all I have left from seed years later. You reminded me, so I'll look for the 'wild' types in the garden. Like many species, they are more subtlely colored, but the three lobed leaf feature helps.
Very complete, well written article. Thanks!
I grew two plants the years before, collected some of the seeds, left some fall, and had one self sow pop up last year. None this year. IT doesn't seem like a huge self sowing thing.
Thanks for reading and chatting!
