Gazania linearis does throw some interesting variants, these two were grown from a seed from a different source than the ones mentioned in the last post. I particularly like the second variant with the orange center bounded by a dark brown partition before the yellow part of the petal.
I'm a high school biology teacher with a passionate interest in plants for as long as I can remember. I have two horticulture degrees, BS and Ph.D. from Cornell and I've worked at the New York Botanical Garden in the past. My plant interests are quite simple: everything! Still, I have a special affection for South African plants, including, of course, pelargoniums (aka "geraniums").
