White Lisbon (bunching)
What's special about White Lisbon (bunching)
Classic scallion — non-bulbing white-stemmed bunching onion. Cold-hardy; sow spring through fall.
Growing this variety
White Lisbon (bunching) follows the same growing basics as Onion. Variety-specific maturity above; everything else below applies to the whole Onion family.
Germination
Spacing & depth
How to plant
Match the variety to your latitude — this is critical. Long-day for the North (14+ hrs), short-day for the South (10–12 hrs), day-neutral in between. Start seed indoors, trim tops to 3" for stronger transplants.
Grower's tip
When tops flop over, bend the rest, then lift and cure in a shady dry spot for 2 weeks.
Soil preferences
Loose, well-drained soil — bulbs rot in wet feet.
6.0–7.0
Compost + bone meal or rock phosphate worked into the planting hole.
Watering
Water in at planting, then only during active growth. Let bulbs go dry during dormancy.
Deep watering at the base. Avoid overhead watering after leaves die back.
Overwatered: soft, mushy bulbs at harvest; basal plate rot. Underwatered: small bulbs, thin necks.
Prefers top-watering — Top-water at the soil surface — keep the necks and crowns as dry as possible to prevent basal rot.
Temperature tolerance
60–75°F (15–24°C) during growth
40–60°F (4–15°C)
Hardneck garlic, shallots, and daffodils need a cold winter to bulb properly. Tender bulbs (dahlia, gladiolus) must be lifted in cold zones.
Container growing
Yes — great in containers
8+ in deep, wide enough to space bulbs 2–3× their diameter
Deep pot for tulips and daffodils; shallow bowls for crocus.
Detailed harvesting
For garlic and onion: dig when the bottom 3 leaves brown and top leaves still stand. Loosen with a fork, don't yank. Cure whole plants 2–3 weeks in a warm, airy, shaded spot.
Post-harvest storage & preservation
After curing, trim tops and roots. Store hardneck garlic 4–6 months, softneck 8+ months in a cool (50–60°F), dry, dark spot with airflow. Never in the fridge.
Culinary, medicinal & other uses
Culinary staple (allium bulbs), cut flowers (tulip, daffodil, lily), forced blooms indoors, or perennial garden color.
Medicinal or traditional uses are shared for interest only — this is not medical advice. Consult a qualified professional before using any plant medicinally.
Seed saving
Propagate by offset bulblets, not seed — bulbs mature much faster from a clove/bulb than from seed.
Not applicable when replanting clones. Cross-pollinated seed rarely comes true.
Save the biggest, firmest bulbs each year and replant. Over generations you build a locally-adapted strain.

From your kitchen — grow onion from what you already have
Two ways to grow from a store onion: replant a sprouting onion for green tops and eventual seed, or (much faster) buy 'onion sets' — tiny dormant bulbs.
- 1For green onions immediately: cut off the root end (1/2 in with roots attached) and plant it root-down in soil. Green tops in 2 weeks.
- 2For a full bulb crop: onions are biennials — a first-year bulb replanted in year 2 sends up a seed stalk. Let umbels dry, rub seed off, store cool.
- 3For real production: skip seed and plant sets or transplants in early spring, 4 in apart, 1 in deep.
Storage: Onion seed only stays viable 1–2 years — buy fresh or save annually.
