Please donate to support our ‘Plants to Save the Planet’ Project. The Project is directed at enabling designers of ‘carbon farms’ and ‘food forests’: agroecosystems of perennial plants, to choose the most appropriate plants for their requirements and site conditions. We are working on a subset of plants in the PFAF database identified as having the most potential for inclusion in such designs. We are adding search terms and icons to those plants pages, and providing a range of search options aligned to categories of plants and crop yields, with Help facilities including videos. More >>>

Edible Uses

Edible Parts: Flowers  Leaves
Edible Uses:

Young leaves - raw[1, 2, 4, 5, 12, 27, 33, 37]. A very mild flavour, with a delicate quality that makes them seem to melt in the mouth, they can be added in quantity to salads[183]. The leaves can be available all year round from successional sowings and will only require protection in the colder winters[K]. Flowers and flowering stems - raw[183].

Our new book Edible Shrubs is now available.

Edible Shrubs provides detailed information, attractively presented, on over 70 shrub species. They have been selected to provide a mix of different plant sizes and growing conditions. Most provide delicious and nutritious fruit, but many also have edible leaves, seeds, flowers, stems or roots, or they yield edible or useful oil.

Cultivation details

A very easily grown plant, it prefers a fairly rich light soil[1, 37] though it tolerates most soils and wet or dry conditions[52]. Prefers a sunny position but tolerates some shade in summer[K]. This shade, plus an adequate supply of water, will slow down the plant's tendency to run to seed[200]. Late sowings will benefit from a sheltered sunny position and perhaps some protection in the winter. Often cultivated on a garden scale for its edible young leaves which, by successional sowing, can be available for most of the year although they will require protection in severe winters. There are several named varieties[183]. The plants do tend to run quickly to seed in the summer though. If allowed to flower, plants will often maintain themselves by self-sowing[K].

Seed - in order to obtain a continuous supply of salad leaves, it is best to sow the seed successionally from early spring to late summer in situ. A late summer sowing might also succeed, and this would supply edible leaves in the winter.

Can I plant valerianella locusta in an hydroponic sistem? can you inform me where can I buy seeds? I am in Portugal and I would like to try it.

Eu planto valerianella que em português se chama alface de cordeiro, mas na terra claro. Compro as sementes na Alemanha que eu saiba não há à venda cá, o que é estranho dado que é originária da bacia do Mediterrâneo. Dá-se muito bem mas apenas no Inverno porque assim que está calor começa a espigar. Neste clima, ou pelo menos aqui no sul dá-se melhor na meia-sombra.

My wife eats this as a salad green almost exclusively here in The Netherlands, but will sometimes mix with other greens. Shape of the leaves holds salad dressing, so less is needed and little is wasted. Here, the plant is called "Veldsla" and is packaged as whole young plants, multi-leaved and with bare roots attached. The two packages I have seen are 100 and 200 grams in weight. Wish this was available in the USA -- they need to get with it so we can find this when we get back. Here, it is priced more or less equally with what would be called mixed field greens in the US. So any fancy restaurant serving this in USA is capitalizing on the 'new' factor, and not the rarity of the plant. Whole greenhouses are dedicated to this stuff over here, so it certainly is nothing new to Europe. "
