Another spiny solanum species. This one's yellow spines emerge from all the major leaf veins. Among the most striking in the species, at least that I've grown. As you can see in the photo above, they are a favorite with flea beetles - just like their edible eggplant cousins.

In 2007 the traded batch germinated better. Perhaps my seed did not have time to properly ripen. Likewise, the 2009 seed had poor germination, in this case perhaps because it was harvested after several hard freezes.
