Propagating Scarlet Hibiscus: Seeds and Cuttings

A gardener asked how to propagate Hibiscus coccineus (scarlet hibiscus). The expert detailed two methods: seeds and softwood cuttings. Seeds require scarification (sanding) and 90-day cold stratification at 40°F, then 70°F for germination—rates were disappointing. Softwood cuttings in early summer are easier and more reliable.

Seed Method:

• Collect ripe pods in early fall.
• Scarify seeds with sandpaper.
• Stratify 90 days in moist medium at 40°F.
• Sow at 70°F; germination is erratic.

Cutting Method (Preferred):

• Take 4–6 inch softwood cuttings in June.
• Remove lower leaves; dip in rooting hormone.
• Root in perlite/peat mix under mist or humidity dome.
• Transplant when rooted.

Cuttings preserve the parent's traits and flower sooner.
