Viola
Common name: Heartease
Overview:
Viola is a hardy perennial often grown as an annual, and is not to be confused with its big brother the hybrid garden pansy V x wittrockiana.
This smaller variety is generally classified as either V x cornuta or V x tricolour (Heartsease)
The flower size across the genus can vary from about 20mm (¾”) which is generally accepted as a Viola to the many hybrids Pansies which can measure 100mm (4”) across.
The Viola grows to around 150mm (6") high with a spread of approximately 300mm (12"), and flowers from May to September.
Deadhead the flowers as they fade to maintain a succession of blooms.

Cultivation:
Week 11:
Sow seed in trays of seed compost and germinate at a temperature of 16°C (60°F).
Germination should take about seven to ten days.
Week 13:
Prick out seedlings into 75mm (3") pots/cell trays of potting compost.
Gradually harden off till planting out time.
Week 20:
Plant out 200mm (8") apart in any fertile, moist, well drained soil, in sun or partial shade.
Week 30:
Alternative sowings can be made now.
Sow seed in trays of seed compost and germinate in a cold frame.
Prick out the seedlings into 75mm (3") pots of potting compost over-winter the young plants in the cold frame.
Plant out in the flowering sites in March or April.
Week 32:
Take 50mm (2") cuttings of non flowering basal shoots and insert into trays/pots of equal parts (by volume) peat and sharp sand, and place in a cold frame to root.
Once rooted, pot up individual plants into 75mm (3") pots of potting compost, and grow on until planting out time.
