Lavandula stoechas
Light: Full sun to light shade; in Phoenix, morning sun with afternoon shade helps reduce summer heat stress.

Mature size: Usually 1–3 feet tall and wide, depending on cultivar.
Bloom: Primarily late winter through spring in Phoenix; occasional fall rebloom with cooler weather and deadheading.
Evergreen / deciduous: Evergreen.
Growth rate: Moderate.
