Use the plant water needs as a guideline. Actual plant water needs will vary for several reasons, including weather conditions, soil type, sun exposure, root depth, wind and elevation. Adjust your watering schedule as needed to meet the plants' needs at your site. Water recent transplants more often than established plants.

Lavender forms a compact and upright, bushy subshrub. Terminal spikes bear fragrant purple flowers in July. It will rebloom a little if the spent flowers are removed. The grey-green leaves are short and linear. This plant grows best in a sunny location with very well-drained soil. This is a tough, adaptable plant for the Pikes Peak area, but well-drained soil is essential for its success. These plants grow in the low water zone at the Xeriscape Demonstration Garden. One location is against a stone wall with a south/southwestern exposure that helps to keep the location dry. They look very good at full bloom. Occasionally, volunteer seedlings appear; as yet it has not become a nuisance. The only other problem is the occasional winterkill of some branches.
Specific cultivars growing at the garden:
'Hidcot - gray-green leaves and deep violet flowers
'Munstead' - long blooming cultivar with medium greenleaves, blue-purple flowers
English lavender has performed well in sunny locations at the Xeriscape Demonstration Garden. They look very good at full bloom and have been reliably deer resistant. Occasionally, volunteer seedlings appear; so far it has not become a nuisance. Over the winter, some branch dieback occurs.
Remove faded flowers to promote continued bloom. In spring, cut back dead growth and shape for symmetry.
