The flower fragrance is most noticeable at sunrise and sunset and may be enhanced by giving plants the bare minimum of water. The plant may be grown as a pot plant. Heliotrope responds to regular fertilizer applications and is not tolerant of the slightest frost. Heliotrope is propagated by seed or cuttings. Take cuttings from especially fragrant plants between late spring and early summer.
Softwood cuttings root in about two weeks at low temperatures.
Seed takes three to four weeks to germinate at 70 degrees and germination can be erratic. Do not allow the plants to get too big before transplanting. Visuals associated with this text.
