A Little About Lavender...
Lavender is a woody, compact perennial herb that goes dormant in the Winter and returns in the Spring. Lavender likes full sun and well-drained, alkaline soil (pH 7-7.5). It is recommended to use decomposed granite or expanded shale if your have heavy clay soil, like our area does.
Lavender is drought tolerant, but does need to be watered regularly the first year until it gets established. It is fairly low maintenance, requiring to be pruned annually in the Spring by about a third, then harvested when the flower buds are formed, but not yet open.
There are many different species of Lavender, each with its own properties. Some are better used for their oils and others for the length of the stems and color. Lavendula X Intermedia ("Lavendin") is a hybrid species that grows very large and produces more spikes. We grow a lot of Phenomenal since it is more resistant to fungal disease (i.e. Root Rot) than some of the other varieties, although we did suffer significant crop loss in 2019 due to the disease. Your can expect Lavender plants to double in size every year with full maturity in three years.
Best of luck with your gardening endeavors!
