The Krimson Princess, one of the Hoya carnosa species’ easiest-care and lowest-maintenance forms, can be a lovely addition to your indoor gardening endeavours. You’ll also appreciate the bouquets of flowers that have a chocolatey fragrance, I’m sure. Before they bloom, the densely packed pink or, less frequently, white clusters of flowers on Hoya carnosa seem like miniature candies. The blooms themselves have a fine covering of hair. The nocturnal flowers release a pleasant aroma that many indoor gardeners liken to vanilla custard, honey, or chocolate, as well as a sticky nectar.
