Lavender Dentata is also known as Fringed Lavender, this species is most often grown in pots or tubs, to be wintered indoors in all but very mild winter regions. Plants form a bushy shrub of grey-green, finely-toothed fragrant leaves, bearing short spikes of lavender-mauve flowers in midsummer. One of the best types for forming into topiary shapes, this is easily pruned to keep a compact size. Choose a location with excellent drainage. In regions with clay soils, a raised bed or rock garden will improve success greatly. Attractive to butterflies.
