Selected Garden Seed

Rainbow Swiss Chard
The selected seed for 2026 is Rainbow Swiss Chard.
Rainbow Swiss Chard is a Garden Hero! The leaves and stalks are edible, it offers fresh greens in summer when spinach and lettuce bolt, and it can tolerate light frosts in fall.
- Germination occurs in 1-2 weeks.
- Brightly coloured stems of yellow, crimson, gold, orange, violet, purple, white, green and pink with contrasting dark green, crinkled leaves.
- Leaves have a lighter taste than the standard chard.
- Grows 60-80 cm in height.
- As Rainbow produces such a colourful display, it is often used as an ornamental in flower gardens and containers.
- Sow seed about 1-2 cm deep and 2.5 cm apart in rows 45 cm apart starting in mid spring. Sowing seed every two weeks until early summer will ensure continuous supply.
- Gradually thin out seedlings to 10 cm apart using the thinnings as baby greens.
- On older plants, harvest outer leaves first by cutting at the base of the stem then working towards the centre as you go.
