Allium ampeloprasum
Safety & Hazards
Although no individual reports regarding this species have been seen, there have been cases of poisoning caused by the consumption, in large quantities and by some mammals, of certain members of this genus. Dogs seem to be particularly susceptible[1].
Cultivation Details
Prefers a sunny position in a light well-drained soil[2]. Prefers a dry position[3]. Succeeds in clay soils[4]. Tolerates a pH in the range 5.2 to 8.3. The bulbs should be planted fairly deeply[2]. The wild leek comes into growth in the autumn, dying down the following summer, and makes a very pleasant winter leaf, either raw or cooked. It is a rather variable plant, especially in the amount of flowers and bulbils produced. The species produces mainly flowers with almost no bulbils, whilst the sub-species Allium ampeloprasum babingtonii (Babington's Leek) produces lots of bulbils and almost no flowers[5]. In addition there are a number of cultivated groups that are considered part of these species. These roups are as follows:- Leek Group (also known as Porrum Group), The cultivated leek is a well-known vegetable, grown for its edible stem which is used mainly as a winter crop. See the separate entry for more information. Kurrat Group Originating from Egypt and the Middle East, it is similar to the cultivated leek, but does not produce a fat stem. It is grown for its leaves, which are often eaten raw. Pearl Onion Group. Cultivated, mainly on a garden scale, especially in Germany, the Nederlands and Italy. This form produces sweet-flavoured bulbils clustered around the base of the main bulb. It can also sometimes form small bulbils in the flower umbel[6]. Elephant Garlic Group. Becoming more popular as a vegetable, the main bulb is formed a number of large, garlic-like cloves that can be used like garlic but have a milder flavour[7]. The cultivar 'Perizweibel' is often used, the bulbils are solid rather than made up of layers and are popularly used for making pickles[7]. This cultivar does not set seed[7].
Propagation
Seed - best sown as soon as it is ripe in a cold frame, though it can also be sown in a cold frame in the spring[8]. Prick out the seedlings into individual pots when they are large enough to handle. Well-grown plants can be planted out into their final positions in late summer or the autumn, otherwise grow them on for a further year in pots and plant them out the following summer. Division in late summer or early autumn. Dig up the bulbs when the plants are dormant and divide them into their individual cloves. They are best replanted immediately, either in the open ground or in pots in a cold frame, though they will also store for some months (preferably only divide the bulbs when you are ready to replant the cloves). There are usually a number of small bulblets produced at the base of the larger bulb. These can be replanted immediately, or stored and replanted in the spring, They take two years of growth before producing a large bulb. Bulbils are sometimes produced in the flowering umbel. These can be harvested as soon as they are ripe in late summer and are best planted immediately, though they can store for some months. The bulbils can be planted direct into their permanent positions, though you get better results if you pot them up and plant them out the following spring.
