Care Provide full sun to light shade and moist but well-drained soil. Two, using containers greatly reduces the chance that they will become infected with powdery mildew. In St. Louis, it is usually grown as a summer annual bedding plant or container plant where it will typically grow 12-18” tall in a growing season.

The garden heliotrope, Heliotropium arborescens, is a tender shrubby perennial, or sub-shrub, of the borage family, with clusters of sweetly-scented blossoms in shades of purple, blue, or white. You may remember heliotrope by its appearance, if not by name, from an elderly relative’s garden that you visited in your childhood. When a cluster of flowers has finished blooming, remove the entire stem to retain shape, energize the plant, and encourage reblooming.
According to the Cornell University Heliotrope Growing Guide, you can start this plant from seeds or from stem cuttings.
They should develop roots within two weeks. Put them in a spot where they will receive ample sun and water and fertilize regularly with an organic plant food. Nan Schiller is a writer with deep roots in the soil of southeastern Pennsylvania.

For most other cut stems, cold water is the way to go.
If you are in an area that is prone to frost, bringing heliotropes indoors is your best option. Check the soil for excess moisture before assuming plants are too dry, or you may make the problem worse.
It can also be grown as a half-hardy annual (grown from seed under glass and planted out after all danger of frost has passed) in those areas. The soil pH should be between 6.6 and 7.3.
This way, you have your heliotropes fully grown and healthy for transplanting into your garden when the next season rolls around, and you can still enjoy the flavorful bouquet year round, by moving them indoors. If you want to grow heliotrope as a houseplant, use a standard garden pot with a top rim diameter of 18 inches. As an added bonus, planting in containers will save you the hassle (and save the plant the shock) of having to repot them to bring them indoors for the winter, which is recommended if you want to grow the plants again next year.

If you are growing plants as annuals, you may bring them indoors as houseplants at season’s end. Fertilization throughout the growing season is required, which poses an additional challenge. Heliotropes like a lot of water, and a lot of fertilizer when in garden beds, but when you plant them in containers, they need even more than they do in the ground. Perhaps the fragrance itself is the sole reason for the buzz, I mean who doesn’t want to smell sweet cherry pie throughout the day?
After cutting the stems, use your pruners to cut up into the stems about an inch, splitting them open a little. Overwintered container plants may grow taller. You can also try spraying them down with a mild fungicide. Florists often dip sappy stems in hot water to slow the run of the sap. GARDENER'S PATH® IS A REGISTERED TRADEMARK OF ASK THE EXPERTS LLC.
