About Chaytor's Lavender
Lavandula x chaytorae · also called Chaytor's lavender, Silver lavender · herb
Chaytor's lavender is a garden hybrid between Lavandula angustifolia (English lavender) and L. lanata (woolly lavender), first raised in England in the 1980s and named in honour of Kew botanist Dorothy Chaytor, who authored a landmark 1937 lavender monograph. It inherits the cold hardiness of L. angustifolia and the striking silvery-white, densely woolly foliage of L. lanata, producing long-stemmed, fragrant violet-blue flower spikes in summer; it is one of the hardier of the non-angustifolia hybrids and performs well across most of the UK in free-draining soil. The most important care requirement is excellent drainage, particularly in winter, as the woolly L. lanata parentage makes stems susceptible to rotting in prolonged wet conditions. According to the ASPCA, lavender (Lavandula) is toxic to cats, dogs, and horses.
Preferred mix: Well-drained to sharply drained; chalk, loam, or sandy soils
Watch for — Winter stem rot: The woolly stems inherited from the L. lanata parent are prone to rotting at the base when wet and cold simultaneously; avoid autumn pruning in exposed locations, dress around the crown with horticultural grit, and ensure no waterlogging occurs near the root zone from October to March.
Why chaytor's lavender needs this mix
Chaytor's Lavender is a Mediterranean dry-hillside plant — it wants a lean, sharply drained, slightly alkaline mix, and rots fast in rich, water-holding soil.
- Chaytor's Lavender evolved on stony, sun-baked slopes — its roots expect to dry out hard and quickly between rains, so the mix must drain almost as fast as you pour.
- A lean, low-nutrient mix keeps growth firm and aromatic; a rich one gives soft, sappy, flavourless growth that flops and rots.
- It tolerates and often prefers a slightly alkaline soil, the opposite of most houseplants.

What goes wrong with the wrong mix
The wrong soil is one of the most common reasons chaytor's lavender struggles, and the damage often shows up weeks later as a watering problem. For this species specifically:
- Rich, moisture-holding compost is the classic killer of chaytor's lavender — especially over a cold, wet winter, when the base of the plant simply rots.
- A peaty, acidic potting mix is doubly wrong: too wet and the wrong pH direction.
- No grit means the rootball stays damp for days, which a dry-climate root system never copes with.
Growing chaytor's lavender in ordinary rich, moisture-retentive compost. Lean it out with at least a third grit, and never let it sit wet over winter.
pH — does it matter for chaytor's lavender?
Chaytor's Lavender likes neutral to slightly alkaline soil, roughly pH 6.5-7.5. If your soil or compost is acidic, a little garden lime or extra grit nudges it the right way — the one common plant where you may add lime.
If you want to check or adjust it, the soil pH guide walks through testing and the safe ways to nudge a mix more acidic or more alkaline.
DIY mix vs a bagged one
Bagged "herb" or "Mediterranean" mixes are usually fine for chaytor's lavender, but most standard composts need cutting hard with grit. The DIY ratio above is cheap and exactly right.
Drainage and the pot
Sharp drainage is everything: a terracotta pot with a big hole, gritty mix and never a saucer left full. Raised beds suit these herbs outdoors for the same reason.
A gritty mix barely breaks down, so chaytor's lavender needs little repotting — refresh the top layer and the grit every couple of years rather than potting on aggressively. When the time comes, our repotting guide for chaytor's lavender covers the timing and technique step by step.
