The deep purple luster of these bunching onions develops consistently no matter what the weather throws at them, delivering genuine bunching onion flavor without compromise. They mature fast enough for multiple harvests in a single season, and with proper hilling technique, you can coax out substantial edible bases rather than thin green shoots. Both spring and summer plantings work beautifully, giving you flexibility to fill your table from early summer through fall.
These bunching onions are harvested young for their tender white bases and green tops, both of which carry full onion flavor. Use them raw in salads and grain bowls, slice them into soups and stews where they soften into mild sweetness, or grill them whole as a simple side dish. The purple color holds its vibrancy through light cooking, making them as striking on the plate as they are flavorful.

Sow seeds directly in well-draining soil in early spring for summer harvest, or in July or August for fall harvest. Plant at the depth appropriate for fine onion seeds (typically shallow, just pressed into soil surface or barely covered).
Harvest bunching onions when they reach harvestable size, typically 60 days after planting. Pull or cut individual shoots at soil level, or harvest the entire plant once it develops a usable base. Both the white base and green tops are edible and flavorful.
