Delft Perpetual is a rare perennial winter leek that sprouts new plants from its base. If the leeks are harvested carefully by cutting just above the ground and leaving the roots and base intact, the offshoots can grow into new leek plants. Alternately you can wait until the leeks flower in their second year, and the offshoots will starts to grow shortly after seed set.

An excellent perennial vegetable for the permaculture garden. Leeks can be used almost interchangeably in place of onions in cooking, but with added greens. The beautiful blue-green leek greens (tops) are also tasty- don't throw them out!

Delft Perpetual was selected out of the "Delft" variety by Frank Morton of Wild Garden Seed, which he describes as "Winter leeks with long well-wrapped shafts, strong upright leaves, and a melting tender quality with light sauté. Slices turn a bright green with cooking, very appealing."

If you do allow these leeks to flower in their second year, the flowers are a range of whimsical white, pink, and purple globes that are adored by pollinators. The seeds do take a long time to mature however, so you may need to cover them with a temporary tunnel to keep the seed dry as they mature.

These seeds are rare and hard to find so don't miss out!

Growing Instructions

Growing instructions: Sow seeds shallowly indoors in January or February. I like to sow my onions and leeks in deep trays so they have enough soil to grow for a few months. Plant outside once they are a few inches tall and harsh frosts have passed. Plant about 6-12 inches apart. Harvest leeks by carefully cutting at the base (this may take a few months to a year to get large enough to your liking). Wait for the offsets to sprout after cutting.
