Lavandula x intermedia, also called Lavandin, is a hybrid cross between Lavandula angustifolia (English Lavender) and Lavandula latifolia (Portuguese Lavender).
- The Lavandin cultivars are slightly less hardy than Lavandula angustifolia, but tend to grow larger and produce more flower spikes than other Lavenders.
- Lavandin plants bloom later the other Lavandula species with their flowering typically occurring in July or August and lasting until late summer.
- Lavandin always make a wonderful floral show in the garden and are a perfect choice as specimen plant or for hedging since they can grow up to 48 in. high (120 cm) and produce long flower spikes up to 30 in. (90 cm). Although Lavandin may be used for culinary purposes, they are more often used as additions to sachets and potpourris.
- Lavandin leaves are gray-green and evergreen in warm winter climates.
- Most Lavandin cultivars are hardy to zone 5 and resist well to fungal diseases in hot and humid climates.
- Both foliage and flowers are highly aromatic. Lavandin are commercially grown for their high yield of oil, which, however, is inferior in quality to Lavandula angustifolia's oil.
