The disadvantage of Tulbaghia violacea is the ever present smell of onions lingering around the planting. This gets worse in wet weather, the force of raindrops bruising the foliage releases the pungent aroma. The advantage are the long straight stems bearing umbels of long lasting violet flowers, which have an agreeable scent. A strong growing and rapidly bulking up rhizomatous perennial native to the Cape of South Africa. Cultural notes often recommend frost protection, in our experience it is a hardy enough species to withstand the winters we experience. Choose a sunny, open aspect and grow in well drained soil.
