How to create your own herb-growing space
Show ordinary and garlic chives literally: hollow leaves beside flat ones with labels. Cut small bunches onto separate plates. This teaches more than two near-identical garlic-chive names lacking reliable trait descriptions.
Choose a suitable growing position
The leaves are useful in an omelette or savoury batter. Start with a small amount to discover how much garlic character you enjoy. Flowers can make a separate accent on the plate, but harvest only from your labelled culinary plant. Ornamental alliums in the same garden do not automatically share that use.
From plant to kitchen
A separate pot keeps plants near the kitchen. After flowering, decide whether to save seed or limit spread. Perennial clumps can have time to flower and regrow. When sharing divisions, pass on names to preserve culinary identity.
Scent, flavour and use
Mild garlic flavour, gentler than a raw garlic clove. Independent trial organisation AAS describes Geisha as mild with a balanced garlic flavour; there is no evidence of a stronger aroma than all other garlic chives.
Care, cutting and harvesting
Sun to light shade and moist, well-drained soil. Let a young clump grow strong first.
Remove old stems. Only let the flower heads you want self-seed; no regular woody pruning task.
Cut flat leaves close to the base. Flowers of correctly identified Allium tuberosum are also edible.
