Pastinaca sativa (common name: parsnip)

Propagation: Seed - sow from late winter to late spring in situ. Seed can be slow to germinate, especially from the earlier sowings[1], it is best to mark the rows by sowing a few radishes with the parsnips. The seed has a short viability, very few will still be viable 15 months after harvesting[1].

Cultivation: Succeeds in most ordinary well-drained soils[2]. Requires an open situation[3]. Prefers a deep rich soil that is not too stiff[4].

The parsnip is often cultivated in the temperate zone for its edible root, there are a number of named varieties[5][6][1]. Normally cultivated as a winter root crop, some cultivars are faster to mature and can be available in late summer[1]. The roots are very frost hardy and can be left in the ground to be harvested as required, though they can also be lifted in the autumn and stored for a few months[1].

The flowers are very attractive to hover flies and predatory wasps[7].

Plants have very few insect pests, though they are sometimes attacked by carrot root fly[7]. Growing onions with the parsnips can reduce the damage[7].

Roots of the wild form can quite quickly be increased in size by selective breeding and good cultivation, it is possible to obtain good sized roots in only 6 years.

Range: Europe, including Britain, from Norway south and east to Spain, the Caucasus and Altai.

Habitat: Roadsides and grassy waste places, especially on chalk and limestone[8].

Edibility: Root - raw or cooked[9][10][11][12][13][6]. When well grown, the cooked root has a very tender texture, though it is rather chewy raw[K]. It is best harvested after there have been some autumn frosts because it will have developed a sweeter flavour[14]. The root is delicious baked, it can also be used in soups etc and can be added to cakes, pies and puddings[6].

Leaves and young shoots - cooked with other greens as a vegetable or added to soups etc[12][6]. Used in early spring[12].

The seed is used as a condiment[12]. Similar in taste to dill[6].

Medicinal: A tea made from the roots has been used in the treatment of women's complaints[15]. A poultice of the roots has been applied to inflammations and sores[15].

The root contains xanthotoxin, which is used in the treatment of psoriasis and vitiligo[15]. Xanthotoxin is the substance that causes photosensitivity (see note above on toxicity)[15].

Usage: The leaves and roots are used to make an insect spray[16]. Roughly chop the leaves and roots, put them in a basin with enough water to cover, leave them overnight then strain and use as an insecticide against aphids and red spider mite[7].

Pollinators: Insects

Habit: Biennial

Soil: Can grow in light, medium, and heavy soils.

Drainage: Prefers well drained soil.

Seed Ripens: Late Summer-Early Fall

Flower Type: Hermaphrodite

Known Hazards: Skin contact with the sap can cause photosensitivity and/or dermatitis in some people[17][18][19]. Parsnip is said to contain the alleged 'psychotroph' myristicine[19].

Also Known As: Peucedanum sativum.
