Growth—

Lavandula x intermedia is a fairly cold-hardy plant, tolerating temperatures down to between -10 and -15°c so long as it has enjoyed a sunny summer[1]. Succeeds in almost any soil so long as it is well-drained and not too acid[2, 3]. Prefers a sunny position in a neutral to alkaline soil[2, 4, 5]. Prefers a light warm dry soil[6]. When grown in rich soils the plants tend to produce more leaves but less essential oils[4]. Established plants are drought tolerant[7]. Very tolerant of salt wind exposure[PFAF]. When growing for maximum essential oil content, the plant must be given a very warm sunny position and will do best in a light sandy soil, the fragrance being especially pronounced in a chalky soil[8]. Lavendin is a very ornamental plant that is often grown in the herb garden and is also grown commercially for its essential oil[2, 4]. This species is a very variable hybrid between the two main species of lavender, Lavandula angustifolia and Lavandula latifolia[3], There are several named varieties[3, 9]. Not a very long-lived plant, it can be trimmed to keep it tidy but is probably best replaced every 10 years[3]. Any trimming is best done in spring and should not be done in the autumn since this can encourage new growth that will not be very cold-hardy[3]. A good bee plant, also attracting butterflies and moths[10, 11, 12]. Lavendin makes a good companion for most plants[13], growing especially well with cabbages[5].

Propagation

Seed. This species is usually a sterile hybrid and does not produce seed. Very rarely, fertile forms arise and breeding efforts are underway to build on this[14]. If seed is obtained, sow it in spring in a greenhouse and only just cover[4]. It usually germinates in 1 - 3 months at 15°c. When large enough to handle, prick the seedlings out into individual pots and grow them on in the greenhouse or cold frame for their first winter, planting them out in late spring after the last expected frosts. Cuttings of half-ripe wood 7 - 10cm with a heel, mid summer in a frame. Usually very easy, a high percentage will root within a few weeks[15]. Grow them on in the greenhouse for their first winter and plant them out in late spring after the last expected frosts. Cuttings 7cm with a heel succeed at almost any time of the year[2]. Layering.
