The plant has aromatic silver grey foliage year round and in summer produces scented flowers in blues, purples, pinks or white. It is good food for bees and once established is a tough, drought tolerant plant.
It is an easy herb to grow on its own or as a companion plant with roses or other summer-flowering bulbs and herbaceous perennials such as Echinacea, helianthus, phlox, monarda and rudbeckia.
HTA consultant David Gilchrist said: "Lavender can add real value to a garden in many ways with its shades of blue flowers and silver leaved backdrop, its scent and the fact that it attracts all sorts of insects and butterflies.
"‘Hidcote’ and ‘Munstead’ are two of the hardiest and most commonly planted cultivars of lavender. To successfully grow lavender, it needs to be planted in a warm, well drained soil with full sun. Chalky soils will enhance the lavenders fragrance. There is also the French lavender to choose from, Lavendula stoechas.
"This is attractive and unusual lavender which is best grown in a warm position, sheltered from the cold winds and frost. It can be container grown very successfully and it holds the RHS Award of Garden Merit as a worthy garden plant.
The plants included within Plant of the Month have been nominated and agreed by the HTA Ornamentals Committee and the HTA Retail Management Group. Point of sale materials can be purchased through HTA partners Hortipak and Floramedia.
