The garden centers around here usually stock CPs in the summer, fall, and early winter. Ironically, I've never seen them in the spring here, I guess it's because they are trying to sell plants that look good -- and let's face it, many temperate CPs don't look very marketable in spring. Lowe's had Neps last year but not this year, Home depot did not have any CPs last year but many this year. It all depends on the manager -- some see CPs as a waste of space that could be used for Orchids, Bromeliads, and any other 'easier' ornamental plants. I agree with others that have said that you should request CPs or ask when the next order comes in, without demand there is no supply.
