Lavandula dentata

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.
