'Mona Lavender' Plectranthus: Months of Lavender Spikes in Low Light

Botanical Name: Plectranthus hybrid

Few plants bloom so reliably indoors for so many months — and fewer are this easy. 'Mona Lavender' is a fast-growing perennial shrub with upright stems, dark-green toothed leaves (purple undersides), and tall spikes of tubular lavender flowers spotted with purple. The shorter days of autumn trigger blooming, so keep it away from artificial light at night. Flowers continue through winter into spring.

Simple Care for Non-Stop Blooms

Pinch and Prune

Pinch stem tips to promote branching and compactness (root the cuttings!). Remove faded flower spikes to encourage more blooms.

Repot After Flowering

Spring, after bloom. Move up just one pot size. Drainage holes essential.

Avoid Two Killers

Hot direct sun and dry soil will kill it fast. If summering outdoors, keep in full shade and well-watered.
