viola flower seeds Viola Cornuta Large Flower Mix Seeds

Viola cornuta 'Large Flower Mix' Horned Violet / Tufted Pansy 'Large Flower Mix'

Masses of large cheerful pansy-like flowers in vibrant cottage colours on neat compact mounds of glossy mid-green foliage — Viola cornuta 'Large Flower Mix' is the cool-season cottage workhorse that flowers through autumn, winter and spring when most other plants have stopped, providing essential cool-season colour for containers, window boxes and front-of-border positions.

If you want cheerful colour in the months when most cottage plants are dormant, Viola cornuta is your answer. The "Large Flower Mix" delivers the substantial pansy-like flower size combined with the superior hardiness and longer flowering season of the cornuta species (unlike standard pansies, Viola cornuta is hardy enough to overwinter outdoors in most UK gardens). The flower mix typically includes vibrant blues, purples, yellows, whites, oranges and bicolours, all with the characteristic "smiling face" pansy markings. Compact 15–20cm habit suits front-of-border, container, and window-box display. Long flowering season: from October through April–May, with some plants continuing to flower throughout mild UK winters. Hardy biennial typically grown as a hardy annual; in mild gardens often behaves as a short-lived perennial returning for a second season. RHS Plants for Pollinators recognised.

A note on growing

Viola seeds, like Pansy seeds, need darkness to germinate — the opposite of most cottage seeds. Cover the seed tray with cardboard or black plastic until germination occurs (10–20 days). Maintain 15–18°C (cool conditions suit Viola genetics; high heat actually inhibits germination).

Two sowing strategies for two flowering seasons:

• For autumn-winter flowering: sow indoors February–March for planting out in May; plants flower from October through winter.
• For spring flowering: sow indoors August for transplanting in autumn; plants overwinter as established rosettes and flower from late spring.

Plant out in sun or light shade in moist but well-drained fertile soil. Deadhead religiously to maintain the long flowering season — without it, plants set seed and decline rapidly.

Where it shines

In autumn-into-spring containers, window boxes and patio pots — Viola cornuta is the workhorse that keeps colour going through the cooler months when summer bedding has finished. As underplanting beneath spring bulbs — Violas continue flowering through the bulb display, providing colour at ground level while the bulbs rise above. At the front of cottage borders for low-growing cool-season colour. In children's gardens for the cheerful "smiling face" flowers. Edible flowers with mild sweet flavour — beautiful as cake decorations or salad garnish.

Plant alongside

For a classic spring container, combine Viola cornuta with tulips (matching cool-season timing with contrasting height) and Forget-me-not 'Victoria Mixed' (matching pastel palette at compatible heights). For autumn winter colour, pair with Pansy 'Swiss Giant Ullswater' (matching habit with larger flowers) and Calendula 'Wintersun' for warm-and-cool seasonal contrast.
