The hardy Primula acaulis is an incredibly versatile plant, it can be used in containers, hanging baskets, as a house or garden plant. Hardy to -25°C (13°F), they produce a wide range of intensely coloured, large blooms from early spring to early summer.
Acaulis “Choice Mix” contains a vibrant and vivid colour mixture, White, yellow, red, purple, pink, orange.
Primula acaulis heralds spring, indoors or outdoors, these charming plants provided a welcome injection of colour at a time when we most need it. Like many cool-season perennials, they do not tolerate extreme summer heat, dying back in early summer; this hardy variety will re-appear again in spring for several years.
In the garden, they perform best in moist, shady locations and grow well in a wide variety of loam or soils pertaining to most average garden situations including heavy clay soils.
Sowing: Sow in summer to autumn or late winter to late spring.
Sow on to a moist seed sowing compost in a tray or cells. Cover lightly with vermiculite and propagate at 15 to 18°C (59-64°F). Germination is inhibited by temperatures above 20°C (68°F). It should begin to take place in around 10 days. Once germination occurs, lower the temperature maintaining it at around 10 to 15°C (50-59°F).
When seedlings have their first pair of true leaves and are large enough to handle, transplant into 7.5cm (3in) pots containing peaty compost. Grow them on at quite cool temperatures until they are established, at around 10 to 15°C (50-59°F) to help avoid any stretching of the plants.
Acclimatise to outdoor conditions for 10-15 days before planting out. Plant them in a humus-rich, moisture retentive soil and in partial shade.
The important factor with this and most other primulas is that the roots should not dry out, so incorporate plenty of organic matter when you plant, mulch well in autumn and spring and water regularly if they are in the open. They are light feeders; providing moderate fertility levels causes them to appear lush and leafy. Cut back after flowering. Once established, they benefit from being lifted and divided every two years in autumn.
In the Home:
Primula needs plenty of light but not direct sunlight. Ensure good ventilation to avoid high levels of humidity. After flowering is over Primula can be planted out in the garden. The plants can then flower again the following season. Remove dead flowers as they will rot and can cause botrytis.
Water with care. Pour water into the saucer or outer pot and remove any excess water left after half an hour. Only water when the soil in the pot feels dry. If the plant starts to wilt, check whether the rootball is still moist. If this is the case, move the plant to a cool spot. Primula has a great capacity for recovery. If the rootball is dry, water the plant.

This species of Primula is native to western and southern Europe (from the Faroe Islands and Norway south to Portugal, and east to Germany, Ukraine, the Crimea, and the Balkans), northwest Africa (Algeria), and southwest Asia (Turkey east to Iran).
Primula is a diminutive of Primus, which means ‘first’. "Primrose" is ultimately from Old French “primerose” or medieval Latin prima rosa, meaning “first rose”. It flowers in early spring, one of the earliest spring flowers in much of Europe. The first sentence of Richard Adams' novel Watership Down is "The primroses were over."
Acaulis means ‘without stem’. The flowers do not have tall stems as in some primula species, they are located immediately on top of the leaves.
Primula, one of the first flowers of spring symbolises hope.
