Mona Lavender' is a fast-growing perennial shrub that's fast becoming a favorite house plant.This shade-lover is an exciting new cultivar that's perfectly suited to growing indoors. Few other plants bloom so dependably indoors, for so many months, and fewer still are as easy to grow as "Mona."Upright stems are densely covered with dark-green ovate leaves with toothed edges. The glossy leaves are evergreen with purple undersides, making this a beautiful house plant year-round.Just when most plants are slowing down in autumn, this flowering beauty sends up tall spikes of tubular lavender flowers spotted with purple. It's the shorter daylight hours that trigger blooming, so don't put it under artificial lights. You'll likely enjoy flowers right through the winter and into spring.
