Heliotrope (Heliotropium arborescens) is a hardy perennial featuring dark purple blooms and a rich vanilla fragrance. The flower grows wild throughout the Southwestern United States and is a state flower of Oklahoma. It is typically grown as a bedding plant. However, heliotrope can be grown year-round indoors as a houseplant that offers dark green foliage, purple blooms and a sweet fragrance.
Fill flower pot half-full with potting soil. If the pot does not have drainage holes at the bottom, create drainage by filling the bottom of the pot with rocks or pebbles.
Gently take the heliotrope plant from its starter pot and place down into the potting soil.
Cover the base of the plant with potting soil. Use enough potting soil so that the roots of the plant are covered and the plant stands up straight.
Water the plant thoroughly. Heliotrope prefers moist soil and should not be left to dry out between waterings.
Place heliotrope in a sunny window. The flower needs full sun to bloom. In addition, make sure the plant is away from drafty windows, where temperatures may dip below 70 degrees.
Feed the heliotrope a traditional amount of plant food after it has become established in the pot (according to the directions on the food's packaging). Generally this occurs within two to three weeks. During the growing season, continue to fertilize your heliotrope regularly according to directions listed on your fertilizer.
