non blooming mona lavender
Is your Mona Lavender plectranthus growing in a container or in a ground bed? Confinement of the roots in a container is one way to force earlier bloom on it. It sounds as though yours is growing well, which indicates that it may just be in a vegetative state, and will bloom once environmental conditions are right or it is stressed enough to induce bloom. The plant will bloom best in full sun.
