Today I thought I'd share with you about an early abundant spring plant that
can be used for food.
Sulphur cinquefoil (Potentilla recta)
In our fields it is everywhere! Below is a quick guide to recognising it, as well
as some uses.
Flower- note the heart-shaped petals in two tones of yellow
Sulphur Cinquefoil
Potentilla recta
Rosaceae
Synonyms:
Erect cinquefoil, Rough-Fruited
Cinquefoil, Five Fingers
Description: Perennial herb that can grow up to
80cm tall. Likes to grow in open fields.
Leaves are
palmately divided into 5-7 deeply toothed and veined leaflets. The
name cinquefoil, which means five leaf or five petal refers either to
the five petaled flower or to the five leaflets that are arranged
like fingers on a hand. Some people think that the leaves resemble marijuana leaves. Most sulphur cinquefoil have seven leaflets
at maturity, but some have five. They are dark
matte-green on top and pale below. The leaves form a basal rosette as
well as forming an alternate pattern up the stalk. At each petiole
there are two jagged stipules attached to the stalk.
Stalk
is woody and green/yellow. Both the leaves and stalk are covered in
soft hairs.
Flower is yellow in two tones, light yellow on
petals and dark yellow towards the centre. It has five petals, each
shaped like a heart. Flowers grow in flat topped clusters (cyme).
Early in the morning the flowers are not yet opened; they open as the
day progresses.
Fruit is small and strawberry-looking and
enclosed within a papery husk. This husk turns brown and dries
in late summer. Inside are many small seeds that fall out once
the husks dry up and open. The seeds are dark brown and
wedged-shaped.
Tap root is fibrous and woody.
Husk and seeds in August
Uses:
This species is
an introduced variety that can become quite widespread. The leaves,
in early spring, or when they are immature, can be picked and added
to any meal you cook. They are not suitable raw in a salad due to
their texture and the fine hairs on the leaves. However, the dried
leaves can be added to bread and muffins. They dry fast and are easy
to crumble up. Their flavour is similar to strawberry leaves
(
Fragaria spp) or rose leaves (
Rosa spp): Fresh, sour
and drying. They are all part of the same family, Rosaceae.
We also use the flower petals as
garnish. They need to be added at the very last minute before serving
because the petals are fragile and do not hold up to a lot of
handling. They look like beautiful little yellow hearts. The fruit is
small and covered in a papery husk. It tastes like an unripe
strawberry. Once the husk dries up, the seeds from the fruit scatter
freely and abundantly. If you pick the plant just before it has
released all its seeds you can put it upside-down in a paper bag and
gather the seeds for muffins or as sprinkling on your yoghurt. They
taste a lot like strawberry seeds. The seeds are tiny, but there is
usually a great abundance of them since the plant tends to grow in
large patches. I find them worthwhile to gather.
The leaves can also be used medicinally
whenever an astringent is called for. The astringency in the plant
helps to tighten the skin and heal wounds. I have used it with great
success when I have bit the inside of my cheek and the puncture wound
has become infected. I make an infusion or decoction of the fresh plant, stalk,
leaves and flowers. I gargle with this liquid three times per day
until I see an effect. After using it for only a day I can already
see a marked improvement and the pain is almost all gone. A tea made from the leaves can also be
drunk if you are suffering from diarrhea.
Many people complain about sulphur
cinquefoil due to its invasive tendencies and how it can make hay of
inferior quality when it gets into the hay fields. We have found that
the sulphur cinquefoil thrives in pastures with poor fertilizing and
low irrigation. Here on the farm we run chickens in large movable
tractors over parts of the fields and it seems as if the cinquefoil
is kept in check where the chickens have been able to scratch and
poop. Where they have not been, the land is much drier and has less
grass and more cinquefoil. The hay from the pasture with the
cinquefoil is popular with goat owners.
Look-alikes:
There are many different kinds of cinquefoil and they can be hard to tell apart. Below are just a few examples.
Graceful Cinquefoil (Potentilla gracilis) is a native species. The flowers tend be one-toned rather than two-toned in colour. Leaves are more finely divided and are more likely to be in a basal rosette rather than on stem. This plant can be used in the same manner as sulphur cinquefoil.
Sticky cinquefoil (Potentilla glandulosa). As the name implies, it has sticky glands. Flower petals are rounded rather than heart shaped. Sepals are very prominent. Also edible. See picture below.
Tomentil/Erect Cinquefoil (Potentilla recta) See caution below!
Caution
Note that there are two species with
the same common name and almost identical Latin names. Sulphur
cinquefoil/ Erect cinquefoil (Potentilla
recta) that we speak of here, (an introduced species from
Eurasia) and Tomentil/ Erect cinquefoil (Potentilla
erecta) that
grows in Europe. Tomentil can not be eaten as food but has
been used for medicine. Any amount over 1g can cause gastrointestinal
problems and issues with absorption of minerals and iron in diet. I
have not seen Tomentil here, but it may be around. An easy way to
tell them apart is by the flower petals. Sulphur cinquefoil has five
petals, Tomentil has four.
