Sulla Plant Care

Sulla (Sulla coronaria) belongs to the Fabaceae family within the Sulla genus. Sulla is native to Malta, Algeria, Morocco, Tunisia, southern Italy and Spain, cultivated for animal fodder and hay, and for honey production.

Sulla displays a spreading ground cover growth habit, reaching up to tall with a spread of approximately . Sulla produces small clusters of pink, purple, or white pea-like flowers.

Sulla thrives in full sun to partial shade.

Well-draining loamy soil with added organic matter. Good drainage is essential for Sulla to prevent waterlogging, which leads to root rot and fungal issues.

Choose a spot with full sun to partial shade and well-draining loamy soil with added organic matter. Avoid low spots where water collects after rain.

Plant container-grown or balled-and-burlapped trees in spring or early autumn, setting the root flare at soil level, and water well after planting.

Prune Sulla while it is dormant in late winter: first remove dead, damaged and crossing branches, then thin lightly for shape.

If it flowers in spring, prune right after flowering instead so you don't remove next year's buds. Never take off more than about a quarter of the tree in one year.

Water deeply in late autumn before the ground freezes, and spread a 5–8 cm (2–3 in) layer of mulch over the root zone, keeping it away from the trunk.

Young and container-grown trees need extra protection: roots in a pot freeze much more easily than roots in the ground.

Sulla can be propagated through seeds, division of root ball.

Sulla is susceptible to aphids, leafhoppers, whiteflies. Inspect the foliage regularly, especially along leaf undersides and stems. Treat infestations promptly with insecticidal soap or neem oil to prevent spread.
