Hey Carol, excellent find at Lowes. I myself have purchased some out of bloom orchids at Home Depot...you can't beat the prices!
You didn't say what type of orchid you have such as a phal or denbrodiums, lady slippers ect... but since you talk of a flower stalk it sounds like you have a
Phalaenopsis Orchid. In that case they bloom about once or twice a year and the blooms can last for awhile. Your orchid is now in a period of rest and probably won't bloom again for another 3 months but this is just an estimate.
One important thing to remember if you are having trouble getting your orchid to flower again is temperature.
Temperature
Cool night time temperatures in the fall encourage flower spike initiation. However, once the flower spike is developed, wide changes in temperature can cause unopened bud to drop off. Temperatures higher than 90 can slow growth. The ideal temperatures for Phals range between 55 and 85 F. For ideal growing try to maintain 60 at night and between 75 and 80 during the day.
Good luck
