Digitalis ambigua seeds – (Grandiflora, Yellow Foxglove)

Description

This is the largest and most spectacular flowered of the yellow foxgloves. It is perennial and long lived. It thrives in partial shade and likes humous-rich well drained but moist soil. It has glossy green, veined leaves, whose flowering stem can reach a height of 70–120 cm (28–47 in). The pale yellow bell-shaped flowers are spaced out on the stem, 3–4 cm (1–2 in) long. The spikes of chocolate netted, large sulphur yellow flowers over rosettes of strongly veined leaves are considered to be amongst the best of the yellow flowered foxgloves. It is the holder of the prestigious Award of Garden Merit from the Royal Horticultural Society.

Sowing advice:
Sow spring, early summer, late summer and early autumn. Cover the seeds with fine grit or compost to approximately their own depth. They can be sown at any time, and germination can sometimes be quicker if kept at 15 to 20 degrees C. However, most seeds can be sown in an unheated greenhouse to wait for natural germination as many seeds have built-in dormancy mechanisms, and often wait for spring before emerging regardless of when they are sown. But spring sowing will obviously give them a full season of growth if successful germination occurs.
