visionspictures.com

A vigorous variety with mid-green to dark green leaves and gives a high yield with a long harvest season from late summer until early winter of stems up to 30cm long and 4cm across, with very little tendency to bolt. Leeks, Allium porrum, are herbaceous perennials usually grown as annual vegetables, with upright stems which can be blanched white, and green or blue-green leaves about 30-50cm long; plants may flower by bolting in their first year, or the following year if left overwinter, with stems up to 1.5m high topped by rounded flowerheads 5-9cm across of hundreds of star-like pale pink to white flowers which are visited by bees, in summer.
