Syn: Digitalis ambigua. Perennial Foxglove

Availability: In stock

Packet Size:100mg
Average Seed Count:600 Seeds


Digitalis grandiflora is one of the few truly perennial foxgloves. Also known as Digitalis ambigua it is a continental species that is attractive and reliable yet remains an infrequently seen specimen in gardens. Extremely hardy, this is one of the toughest and best performers of all the foxgloves.
The plants form low rosettes of dark green leaves, bearing upright stalks of beautiful creamy-yellow bells through the summer. Each large flower is intricately marked with brown on the inside.

Digitalis grandiflora, grows to around 80 to 90cm (32 to 36in) tall. This compact plant does not need staking and is a good choice for the border or woodland garden.
In a mixed border the lovely soft shade allows this plant to blend with almost anything in the garden. The flowers are excellent for cutting and, as with all foxgloves they are highly attractive to bees.

  • Awarded the RHS Award of Garden Merit
    Digitalis grandiflora has been awarded the Royal Horticultural Society’s Award of Garden Merit (AGM).

Sowing: Sow indoors in late winter to spring or sow directly outdoors in late summer to autumn
Sow seeds on the surface of a peaty soil. Do not cover or bury seeds as the seed needs light to germinate, just press seeds lightly into the earth. Keep seed in constant moisture (not wet) they will usually germinate in 2 to 4 weeks at around 20°C (68°F).

Sowing Indoors:
Sow in late winter to spring Sow seed thinly in trays of compost and place in a cold frame or greenhouse. Once germination occurs keep in cooler conditions. Prick out each seedling as it becomes large enough to handle, transplant into 7.5cm (3in) pots or trays to grow on. Gradually acclimatise to outdoor conditions for 10 to 15 days before planting out once all risk of frost has gone. Transplant to the flowering position planting 30cm (12in) apart.

Sowing Direct:
Sow in late summer to autumn directly in a well prepared bed. Sow very thinly in drills 30cm (12in) apart. Firm down. Keep the plants moist and free of weeds. Thin out the seedlings to 15cm (6in) apart when large enough to handle.

The plants establish and grow leaves in the first year, it will send up large spikes, then flower and produce seeds in the second. As a rule, they are hardy plants and can cope with any soil unless it is very wet or very dry. They are fairly disease resistant, although the leaves may suffer slightly from powdery mildew if the summer is hot and humid.
If you cut the stalk down before it goes to seed, it will generally rebloom and, if you wish, you can reseed from the second showing. Self-sown seedlings producing different shifting, untutored patterns of flowers each year, they can be easily transplanted to the location you want them to bloom. They are best transplanted when the leaves are about 10cm long. Make sure the newly moved plants are watered very well to help them establish.

Saving seed:
Cover the flowerspikes with paper bags (such as those used by bakers to wrap baguettes) to collect the seeds. When the seedheads have dried, shake them to remove the seed and scatter them where you want them to grow.

Digitalis is a source of digitalin used in cardiac medicine, it slows the heart. The whole foxglove plant is toxic, no part is edible and if eaten it will cause severe discomfort, in a child or small animal it could cause death. Fortunately it tastes very bitter and causes irritation of the mucous membranes in the mouth, actually causing pain and swelling. It also causes diarrhoea, nausea and vomiting, so if it does get in, it soon comes out!
Because of these factors, it is not really a problem for wildlife, human or otherwise. However if you ever find a child who has been around this plant with symptoms of oral irritation, grab a stem or two and get to the emergency room! Wear gloves when handling plants or seeds, plant only where children or animals will not have access.

Plant Uses:
Shade/Woodland Garden. Cottage/Informal Garden, Cut Flower Arranging, Flowers Borders and Beds, Wildflower Gardens or Wildlife Gardens

Other Uses:
If foxgloves are grown near most plants they will stimulate growth and help to resist disease and if grown near apples, potatoes and tomatoes their storage qualities will he greatly improved. Foxgloves in a flower arrangement make all the other flowers last longer - if you do not want the actual flowers in the vase make some foxglove tea from the stems or blossoms and add to the water.

Digitalis grandiflora is a flowering plant in the family Plantaginaceae.
Native to Southern, Middle and Eastern Europe, Asia Minor and Western Siberia, Digitalis grandiflora is not normally found wild in the British Isles. It grows in deciduous woods and glades, on mountain meadows, from foothills to mountains. It is a protected species in some countries (e. g. Germany).
Digitalis grandiflora “The large yellow foxglove” is often confused with its cousin Digitalis lutea “The small yellow foxglove”. D. lutea has more tubular flowers (almost the same diameter for the entire length) that are crowded down one side of the spike. D. grandiflora has larger more bell-shaped flowers (wider at the opening). In each of the throats are fine, netted purple-brown markings.
The genus Digitalis was traditionally placed in the figwort family, Scrophulariaceae, but phylogenetic research led taxonomists to move it to the Veronicaceae in 2001. More recent phylogenetic work has placed it in the much enlarged family Plantaginaceae.

The name Digitalis is a latinisation of the German name 'fingernut' from the Latin digitus meaning 'a finger'. The flower resembles the finger of a glove. The English name comes not from foxes, but from the phrase 'folks' gloves' because it was thought that the flowers were used as gloves by fairy folk. Another common name is “Fairy Thimbles”

Folklore & Legend:
The flower meaning is insincerity – Folklore tells that bad fairies gave the flowers to the fox to put on his feet to soften his steps whilst hunting ! The foxglove was believed to keep evil at bay if grown in the garden, but it was considered unlucky to bring the blooms inside.
