Yellow foxglove is a clump-forming perennial accepted as *Digitalis grandiflora*, with *Digitalis ambigua* listed as a synonym. Dark-green evergreen foliage supports upright spikes of tubular, creamy-yellow flowers. ## Flowering and placement The RHS lists a mature height of 0.5–1 m and a spread of 0.1–0.5 m. It grows in full sun, partial shade, or shade, in soil types ranging from chalk and clay to loam and sand. The [RHS species profile](https://www.rhs.org.uk/plants/5856/digitalis-grandiflora/details) gives these size and growing details. The [Kew Plants of the World Online account](https://powo.science.kew.org/taxon/60453625-2) accepts *Digitalis grandiflora* and lists *D. ambigua* among its synonyms. ## Garden character This foxglove’s pale yellow bells add a softer color to borders and woodland-style plantings. The RHS describes the species as a herbaceous perennial with evergreen foliage; its flowering stems rise above a clumping base. ## Maintenance Keep plants watered while they establish and avoid leaving the soil dry for long periods. Remove fading flower stems to tidy the clump or reduce seed production. All foxgloves are toxic if eaten, so wear gloves when handling plants or seed and keep them away from children and pets; see the [RHS foxglove growing guide](https://www.rhs.org.uk/plants/foxglove/growing-guide) for general care and safety.
