Star of India Achimenes

This perennial tropical plant is typically grown as an indoor, container plant.  It can also be grown as an annual in non-tropical environments.  Its habit makes it suitable for hanging baskets.  Artificial lighting can be used when natural light is not available.  When planting, use a humus-rich soil such as African violet mix and choose a site that is in an area of bright but indirect lighting.   Avoid direct sunlight.  During periods of active growth, fertilize weekly.  This tropical bulb will not succeed in temperatures below 50 degrees.  Ideally, temperatures between 50 and 70 degrees are best. The optimum daytime temperature is in the mid-'70s.

Flowers bloom from summer into fall.  When the blooms cease to bloom in the latter part of the year, watering can be reduced.  Reduced watering will send the plants into a dormant state and tubers with some resemblance to small pinecones will begin to form.  These tubers, which form under the soil as well as along the stems, can be collected after the plant has lost its leaves, and saved for replanting.  Store in a dry atmosphere, such as in potting soil or vermiculite with temperatures between 50-70 degrees.  Plant at a depth of 1/2-1".
