THIS LITTLE-KNOWN SPECIES (apparently first discovered and named by famed British plant explorer Andre Jordan) reminds me of all the plants I used to bid on at rare-plant auctions. The thinking always seemed to be that the harder it was to grow, the more valuable it was–and up went the bids, sky-high. The older I get, the less I feel that way, preferring willing subjects to finicky ones. You? Any Punius insipidus types in your yard?
