Lavandins are English lavender hybrids. These hybrids are workhorses in the lavender patch. They have large, gray leaves. They grow faster and larger than regular English lavenders, yet they still have the fragrance and plant qualities you'd expect from this group.
Lavandins bloom conveniently right after the traditional English lavenders are finished, extending the flowering season. Like English lavender they are hardy in USDA zones 5 to 10.
'Phenomenal' is a standout variety for both hot and cold climates. Its ability to tolerate humidity have made it the go-to lavender for the Southeastern US, while its ability to survive winter without much dieback have increased its popularity in northern locations..
Some nice choices within the Lavandin group include 'Grosso' with its long purple flower wands. There's a white flowering version of 'Grosso' as well. 'Edelweiss' is a white flowering, very fragrant Lavandin. 'Provence' is a classic Lavandin with fragrant, purple flowers, high in essential oils that are used in the French perfume industry.
French lavender varieties are hardy to zones 8 to 10, not commonly used in culinary dishes and not as fragrant or showy as the English lavender. They have gray, serrated leaves. Keep these cut back to 3 feet tall to maintain the quality of the plant.
’Goodwin Creek Grey' is a nice French lavender variety. Yellow lavenders such as 'Chiffon Yellow' blooms around the time of French lavender and grows in a similar setting. It has attractive yellow-colored foliage and flowers that are mostly used for ornamental purpose.
Spanish lavender such as 'Anouk' is also mostly used for the plant's beauty and eucalyptus fragrance, and not as much in the kitchen. It's hardy to zones 8 to 11 and is better adapted to humid conditions than other lavenders. These lavenders are known for their unusual two-toned, pineapple-shaped blooms.
Working with Lavender in the Garden
Whatever variety of lavender you decide to grow, be creative about where in the landscape you'll plant it.
Lavender thrives in full sun, well-drained soil, and without competition from other plants. Planting lavender where it will not thrive eventually spells death to that plant.
