Description
Plectranthus amboinicus is a succulent shrub with thick fleshy stems and fleshy green pleasantly aromatic leaves thickly studded with hairs. It grows up to 3.3 feet (1 m) tall.

Flowers are pale purplish and appear on a short stem in dense whorls at distant intervals in a long slender spike-like raceme.

Hardiness

How to Grow and Care
Water Cuban Oregano when the top 1 to 2 inches (2.5 to 5 cm) of its soil becomes dry. Apply 1 inch (2.5 cm) of water from a garden hose directly to the surrounding ground. Water the plant during mid-morning hours to allow moistened foliage time to dry before nightfall. Never water so frequently that the soil becomes soggy or develops standing water.
Apply 1 tablespoon of 10-10-10, slow-release, granular fertilizer per 1 square foot (930 Square Centimeter) of the Cuban Oregano's soil in spring, just as new growth begins on the plant. Spread the fertilizer in a band around the Cuban Oregano, keeping it 6 inches (15 cm) from the plant's stems to prevent fertilizer burn. Mix the fertilizer granules into the top 3 inches (7.5 cm) of soil with a rake or garden fork. Water the area immediately to activate the fertilizer. Reapply the fertilizer every three months throughout the plant's active growing season.
