Thanks Elaine .. I've more than my share of clestogamic plants .. , violets and Pes tigridis morning glory .. I really wasn't looking forward to another one - tho the Jewel Orchid can stand alone with it's foliage so even if it was it would probably be ok.
Hoping mine is as pretty as yours when it blooms!
Forgot to add that some flowers have a very short window of scent. MG's for example are fragrant for about 2 hours starting around 10am in the morning.
