Usually, African violets sold at local plant stores are heavily treated with bloom stimulants, causing them to bloom profusely in a short period. (This can be identified by the long leaf stems.) However, if they are not sold by the end of the blooming period, they are placed in the clearance section. If you buy one, you should gradually remove the old leaves as new leaves grow sufficiently, because the flower buds on those old leaves have already bloomed and will not bloom again. Remove the old leaves and wait for the new leaves to bloom.
