Sweet

Scientific Name: Lavendula heterophylla (L.dentate x L.latifolia).

Flowers: These plants have long, narrow flower heads and pale blue or violet individual flowers. The flowers smell strongly--a bit different than other types of lavender--but they have the sweetest smell of all non-English lavender types. The stems tend to be tall and straight.

Plants and foliage: Fast grower up to 3 feet tall and 3 feet wide. Long, narrow leaves can be serrated and are a felted, gray-green. Vulnerable to sooty mold.

Hardiness: Hardy to 15 degrees F.

Culinary Use: Much like English varieties, can be used in recipes from desserts to meats.

Notes: This variety of lavender is the earliest variety of lavender to bloom in the spring. The plants are very oily, and Nigel says they are the ones that leave the strongest scent on the pickers when being harvested. Great as potted plant. Leaves are dimorphic
