Tree Onion is a perennial allium that produces small edible bulblets in clusters at the top of tall stems, offering a unique vertical garden element. Hardy and productive, it yields both aerial bulbs and underground bulbs for culinary use.
Why grow it
Tree onion differs from standard bulbing onions by producing most of its yield as aerial bulblets rather than a single underground bulb, making it useful for gardeners seeking continuous harvests from a single planting. The aerial bulbs mature reliably without day-length constraints that affect many onion varieties, and the plant's perennial habit allows multi-year harvests without replanting. It supplies both storage-stable aerial bulbs and smaller underground sets, offering flexibility in culinary use and seed propagation.
Watch out for
The aerial bulblets can become top-heavy as the stems elongate, sometimes requiring staking or support in windy locations. The plant spreads vegetatively through bulblet production and may self-seed, so containment may be needed if preventing volunteer plants in adjacent beds matters to your garden plan. Bulblet viability and storage duration vary with growing conditions and harvest timing.
