Propagate Heliotrope From a Cutting guide illustration

Take a stem cutting in late summer to clone scent and color. Seed is slower and less true on a named plant.

Toward the end of the season, cut a 5-inch stem just below a leaf node. Strip flowers and lower leaves, dip in rooting hormone, and set it in a sterile seed mix or sand and perlite. Keep it evenly moist and warm until it roots. [1] Roots often show in about two weeks. [2]

Can I grow heliotrope from a cutting?

Yes. A late-summer stem cutting with hormone clones the parent. That is the reliable path for a named scent kind.

How to root a heliotrope cutting

  1. Cut a 4 to 6 inch green shoot just below a node. Remove flowers and the lower leaves.
  2. Dip the cut in rooting hormone. Insert it into moist sand and perlite, or a seed-starting mix.
  3. Keep bright, indirect light and even moisture. A loose plastic bag holds humidity. Avoid hot direct sun on the cutting.
  4. When new leaves appear, pot it on. Grow it frost-free until you plant out after the last frost.

Cuttings vs seed — when to clone a named plant

Seed-sown plants are slow, and they may not match a named kind. Cuttings give you a uniform plant with the same scent. [3] A leaf in a jar of water is a weaker bet than a prepared stem cutting. [4] For the sow ol, see Growing Heliotrope from Seed. Do not take Florida dune plants from the wild.

If you need Fragrant Delight next year, root a cutting now — do not wait on seed.

FAQ

Can I root a leaf in water?

A stem cutting with hormone in a draining mix is the reliable method. A leaf in a jar is slower and less sure.

When will a cutting bloom?

After it roots and you grow it on through winter, then plant it out in warm weather. Do not expect a full show the week it roots.
