Each species of lavender has its own unique characteristics and is suited to different climates and uses. In addition to these, there are many cultivars and hybrids developed for specific qualities such as color, fragrance, or oil production.

Physical Characteristics:

Lavender leaves are typically narrow, grey-green, and covered with fine hairs, with some species having serrated edges. The flowers grow on spikes that rise above the foliage and are usually purple, blue, or lilac, though some varieties can be pink or white. Depending on the species and growing conditions, lavender plants generally range from 1 to 3 feet in height.

Growing Conditions:

Lavender thrives in temperate climates with dry, sunny conditions, being drought-tolerant and preferring well-drained soil. It grows best in sandy or gravelly soils with good drainage and a neutral to alkaline pH. Overwatering can lead to root rot, so it is essential to allow the soil to dry out between waterings.
