About Digitalis 'Camelot Cream'

Digitalis purpurea 'Camelot Cream' · also called Camelot Cream foxglove · flowering

'Camelot Cream' is an F1 foxglove bred to flower in its first year from an early sowing, producing tall spires densely set with cream bells freckled maroon inside. Vigorous and uniform, it behaves as a short-lived perennial or biennial in part shade and rich, moist, well-drained soil. Like all foxgloves it is toxic, with cardiac glycosides throughout.

Cold limit: USDA 4-9 (short-lived perennial / grown as biennial) · RHS H5 (-23 to 27°C)

Watch for — Crown rot in wet soil: Heavy, waterlogged ground rots the rosette over winter. Provide rich but free-draining soil and avoid winter wet around the crown.

What digitalis 'camelot cream''s hardiness rating actually means

Yes — digitalis 'camelot cream' is genuinely cold hardy. Rated RHS H5 and USDA 4-9 (short-lived perennial / grown as biennial), it lives outdoors all year and needs winter cold rather than protection from it. Its RHS rating of H5 means: Hardy in most of the UK and in cold winters. On the US scale that maps to USDA 4-9 (short-lived perennial / grown as biennial) — the zones where it can be left outdoors year-round.

Minimum temperature — and what happens below it

Minimum survivable temperature is roughly about −15 to −10 °C. Digitalis 'Camelot Cream' is built for winter — once established it takes hard frost and snow in its stride.

Concretely, for digitalis 'camelot cream' as it gets too cold:

It tolerates winter lows to about −15 to −10 °C once established.
Below its rated zone, the visible damage is browned or blackened top growth and, in the worst case, a killed crown or root.
First-year, newly planted, or container-grown specimens are noticeably less hardy than established garden plants — the roots are exposed.

Can digitalis 'camelot cream' go outside or overwinter — and where?

Plant it out within USDA 4-9 (short-lived perennial / grown as biennial) and it overwinters with little or no help.
It does not want to come indoors — a warm winter room actually weakens a hardy plant by denying it dormancy.
The real risks in its range are waterlogging, wind-rock on young plants, and a late hard frost on new growth — not ordinary winter cold.

Work back from your local frost dates with the frost-date calculator: the last spring frost and first autumn frost are what really decide when digitalis 'camelot cream' can be outside. US growers can check USDA zones; UK growers should use the RHS hardiness ratings, which match the H5 figure above.
