A. tuberosum. This flat-leaf variety of Garlic Chives seeds has a strong garlic flavour and aroma. The white flowers and stalks are used (only a small amount is needed), to add the pungent taste of garlic to salads, vegetables, dumplings, and stir-fries. Popular in Asian cuisine, garlic chives are also known as ku chai in Chinese. While the leaves and flower stems are delicious and useful in the kitchen garlic chives are also very attractive flowering plants. Use this herb as companion plants to repel aphids from flowers or vegetables prone to attack.
Chives have been in use as a culinary herb in China since around 3,000 BC. It was Marco Polo who returned westward with the notion that they made good eating, but chives were not popular in European gardens until the 16th century.

Allium schoenoprasum & A. tuberosum
Season & Zone
Season: Cool season
Exposure: Full sun
Start indoors February to May, and transplant or direct sow once the soil has warmed in late spring. Optimal soil temperature for germination: 19°C (65°F).
Sow 5mm-1cm (¼-½”) deep and keep moist until germination. If starting indoors, use bottom heat and plant 10-15 seeds per cell in a 72 cell plug tray. Transplant either into containers or into the garden once the soil has warmed up. Space clumps 15cm (6″) apart.
Clumps of chives spread to about 30cm (12″) across. They should be divided at that point and replanted to stand 30cm (12″) apart or broken up for containter planting. Remove flower stems before they open to increase foliage production. Keep chives watered evenly throughout the season. For a winter crop, try digging up a small clump after the foliage dies back in the fall. Plant this in a container using loamy potting mix, and bring indoors to a warm, and very bright windowsill.
The whole plant can be cut down to 4cm (2″) from the ground. Use scissors and take as much as needed. Chives don’t dehydrate well, so use fresh portions regularly. The flowers can be used in salads or to flavour vinegars.
In optimal conditions at least 65% of seeds will germinate. Usual seed life: 3 years.
Chives improve the flavour of carrots and tomatoes, and make a good companion plant for Brassicas. They help to repel aphids, carrot rust fly, and Japanese beetles. Avoid planting near beans and peas.
