10 Yellow Rose of Sharon Seeds – Hardy Heirloom Hibiscus Hamabo Flowering Shrub

Yellow Rose of Sharon (Hibiscus hamabo) is a hardy, heirloom flowering shrub prized for its soft yellow blooms and long summer display. This coastal-native hibiscus brings a tropical look to temperate gardens, growing as an upright, multi-stemmed shrub with lobed green foliage. It works beautifully as a flowering hedge, a mixed-border accent, or a container specimen on a sunny patio.

Each bloom opens in shades of pale to warm yellow with a darker crimson center, attracting bees, butterflies, and other pollinators. Because it is more cold-tolerant than many tropical hibiscus, it can be grown in a wider range of temperate gardens when given a sheltered, sunny position.

Planting & Care

Sow seeds indoors in a light, well-drained seed-starting mix. Press seeds gently into the surface and cover lightly, keeping the medium consistently moist but not soggy. Provide warmth and bright light during germination, and transplant seedlings into individual pots once they are large enough to handle.

After the last frost, acclimate seedlings gradually to outdoor conditions before planting in a sunny, sheltered spot with well-drained soil. Water regularly during the first season to help roots establish, then reduce to moderate watering. A light mulch helps conserve moisture and suppress weeds. Prune lightly in late winter or early spring to shape the shrub and encourage fresh growth.
