Several years ago, my husband and I cleaned out the 3' x 40' strip of soil between our house and our neighbors. There were several roses that were salvaged, but everything else was removed. This buffer zone between houses needed soil amendments, irrigation changes and plants that could handle hot afternoon sun. My husband wanted color and I wanted scent, so we compromised. He purchased two crape myrtles in red and plum and I went shopping for lavenders. Knowing that lavender is a Mediterranean plant, has few problems (root rot, mildew and rust), required little water and LOVED the hot afternoon sun, made it an ideal choice. The flowers would be harvested to use for decorating and smell, a real bonus.  Many of the plants located at the nursery would grow too large for this narrow strip. Searching through the plant inventory at a local herb farm, Gros Bleu Lavender (Lavandula x intermedia) was found and it only grew to 13 inches. The plant marker also noted that it had extremely long flower heads and navy blue flowers. Eureka!  My search was over and I  have not been disappointed with my choice. They finished blooming last month and have been trimmed back to compact round orbs to keep them tidy and healthy, ready to fill out and scent our garden again next year!
