About Foxglove 'Camelot Lavender'

Digitalis purpurea · also called Camelot lavender foxglove, Common foxglove · flowering

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.

Mature size: 120–150 cm tall in flower; rosette 30–45 cm

Indoor size vs how big it gets in the wild

Foxglove 'Camelot Lavender' reaches its full size within one growing season — there is no "long-term" size, just how big it gets before you harvest or it dies back. Indoors and in a pot, expect 120–150 cm tall in flower. In the ground with no restriction it is a completely different plant — rosette 30–45 cm — which is why the pot, the light and the pruning matter so much for the size you actually end up with.

It sizes up fast and once, racing from seedling to full size in a single season; after cropping it is finished, so size is a within-season question.

Growth rate and years to mature

Foxglove 'Camelot Lavender' is a moderate grower. Realistically, expect a single growing season — it reaches full size in one year, then is done. Its feeding profile backs this up: apply a balanced slow-release fertiliser in spring during the second year (rosette stage). a high-potassium liquid feed monthly during the flowering season improves spike length and flower number.
