A showy biennial or short-lived perennial foxglove producing tall spikes of large, lavender-purple tubular flowers with contrasting spotted throats in early to midsummer. Part of the Camelot series with outward-facing blooms on tall, sturdy stems. Highly toxic to humans, pets, and livestock — all parts contain cardiac glycosides.
Preferred mix: Fertile, humus-rich, moist but well-drained loam or woodland soil
Watch for — Crown rot: Overwintering rosettes can rot in waterlogged soil. Improve drainage or grow in raised beds.
Why foxglove 'camelot lavender' needs this mix
Foxglove 'Camelot Lavender' is a Mediterranean dry-hillside plant — it wants a lean, sharply drained, slightly alkaline mix, and rots fast in rich, water-holding soil.
- Foxglove 'Camelot 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 foxglove 'camelot 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 foxglove 'camelot 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 foxglove 'camelot 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 foxglove 'camelot lavender'?
Foxglove 'Camelot 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 foxglove 'camelot 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 foxglove 'camelot 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 foxglove 'camelot lavender' covers the timing and technique step by step.
