Zebrune

Family: Amaryllidaceae Vegetable

Silky, pale-gold shallot bulbs are laced with bold, zebra-like maroon striping—an eye-catching harvest that brings a gentle, sweet allium flavor with a mellow bite.

Zebrune forms tight, well-filled clusters with a firm, dry-skinned texture that stores beautifully and roasts up with a caramel-soft tenderness. Grow it for fresh, savory use in sauces and slow-simmered favorites, or for pickling where its striking stripes stay vivid and elegant.

Culinary Notes

Chef's Note

Zebrune’s stripe-laced, high-density bulbs give you a sweet, mellow shallot that melts into sauces instead of turning sharp or watery. It roasts into caramel-soft tenderness while keeping enough structure for wedges, and its flavor stays beautifully aromatic in both tangy pickles and butter-thick reductions.

Best Uses

low-and-slow shallot jam or caramelized base for sauces
roasted wedges for caramelized edges and spoonable centers
quick pickling to keep the striped look crisp and tangy
thin slicing raw in vinaigrettes or warm butter sauces for a mellow bite

Frequently Asked Questions

What pest or disease most commonly troubles Allium cepa var. aggregatum (zebrune/shallot-like onions), and how do I treat it?

Watch for onion thrips and downy mildew—thrips cause silvery streaks and distorted leaves, while downy mildew shows gray-purple fuzz on leaf tips in cool, humid weather. Remove and discard the worst leaves immediately, then spray an approved insecticidal soap (for thrips) and a copper-based fungicide during the next humid window (for mildew). Space plants for airflow and avoid wetting foliage when watering, since damp leaves trigger mildew quickly on Allium crops.

How often should I water Allium cepa var. aggregatum during the 90-day growing season?

During active leaf growth, keep the top 1–2 in (2–5 cm) of soil consistently moist but not soggy, typically watering about 1–2 times per week depending on rainfall and your soil’s drainage. When bulbs begin to swell (mid-season), reduce frequency so the soil dries slightly between waterings, because overly wet soil late in the cycle increases rot. Stop regular watering during the last 2–3 weeks before harvest so the necks can dry down.

How can I tell when my Allium cepa var. aggregatum is ready to harvest?

Harvest when about half the leaves have yellowed and fallen over, while the remaining tops are still partly green, typically around 90 days. Gently lift a plant to check: the clusters should feel firm with papery outer skins. Cure the harvested onions in a warm, airy spot for 1–2 weeks until the necks are fully dry, then trim tops.
