The nearest grocery store we have here have a nice floral and plant kiosk..I always circle around there before I continue shopping. Last October my hubby got me 3 orchids, so it is now my rescue orchids since they were so dehydrated, and done with its blooms. Just annoying that the tag does not even try to id what orchid group it belongs to. It just says the orchid sellers name..duh..well, will just see if it manages to bloom what it is.
I see lot of poinsettia, cyclamen and amaryllis in our local stores now as the holidays are coming.
Maybe it is just a seasonal/location thing, as to why some stores do not carry lots of plants. With the holidays, the focus will be food and other gifts, and when Spring comes they will start carrying more plants again.
