Other uses and the list of native
Young leaves - cooked as a potherb and added to soups etc[1, 2, 9, 12,

The following are only included for some plants.
- Leaves (Fresh weight)
- 'Red Welsh' 'Early Red' 'Ciboule Commune Rouge'
- An old form of the perennial bunching onion...
- The flowers have a spicy apricot-like fragrance
- Latin name.
- The botanical name of the plant. This is an indexed field and is the primary key.
- Common name.
- One common name (where available) for the plant. It does not list the wide range of
common names that many plants have.
- The family that the plant belongs to. An indexed field.
- The person(s) who named the plant.
- Botanical references
- A bibliography of the most relevant
books (usually a flora) that
contain a botanical description of the plant.
- Other botanical names the plant has been known by. Sometimes there
is disagreement amongst the botanists as to which is the correct name
to use. Search's for Latin names will also check the synonyms.
- Known hazards.
- Any records we have of toxicity or other harmful aspects of the plant.
- The regions of the world where the plant grows wild. One limit to
this field (22/01/93) is that if the plant is native to Britain I
haven't put down the other areas in which it grows. This will be
changed as time permits. There is also a table listing the continents
the plant grows. In the web version a table has been created listing
general areas where the plant grows, this has been done by just searching for
particular strings in this field, you can see the possible areas
- A description of the habitat where the plant grows wild.
- Type of plant. (Annual, perennial, tree etc). An indexed field.
- Whether the plant is deciduous or evergreen. This applies mainly to
trees and shrubs but is also used when we know that any other type of
plant is evergreen. D = deciduous, E = evergreen.
- A value from 1 to 5.
1 denotes plants of very minor uses,
2 means reasonably useful plants,
3 covers the range of plants that could be grown as standard crops,
4 is for very useful plants whilst 5 denotes those of great value.
A very subjective evaluation.
- How tall the plant is expected to grow in Britain, in meters.
- How wide the plant is expected to grow, in meters. This field is
rather lacking in information.
- How hardy is it on a scale from 1 - 10. One will survive arctic
winters, ten is tropical. Cornwall is about eight, but can grow some
plants from zone nine. Most of Britain is zone seven, going down to
zone six in the north and four in the mountains. An indexed field.
- Growth rate.
- How fast the plant can grow. F = fast, M = medium, S = slow. This
applies mainly to trees and shrubs but a lot of entries are blank
because we just do not have the information.
- In leaf
- Months of the year that the plant is in leaf. 1 = January, 12 =
- Flowering time.
- What time of the year does the plant flower? Recorded in months, 1
= January, 12 = December.
- Seed ripe.
- What time of the year does the plant produce ripe seed?. Recorded
in months, 1 = January, 12 = December.
- Is the plant know for its scent.
- Flower type.
- H = hermaphrodite (the flower has both male and female organs). M =
monoecious (individual flowers are either male or female, but both
sexes can be found on the same plant). D = dioecious (individual
flowers are either male or female, but only one sex is to be found on
any one plant so both male and female plants must be grown if seed is
- Can one plant growing on its own produce fertile seed without being
pollinated by any other plants? Y = Yes, N = No, a blank entry denotes
that we do not know.
- How is the plant fertilized? Can be either
Lepidoptera (Moths & Butterflies),
Apomictic (reproduce by seeds formed without sexual fusion),
Cleistogamous (self-pollinating without flowers ever opening).
- Type of soil the plant prefers. L = light (sandy), M = medium
(loam), H = heavy (clay). An entry here does not specifically mean that
a plant will tolerate the extremes of very heavy or very sandy soils,
for further details on this refer to the next two fields. An indexed
- Does the plant require a well-drained soil? Many plants cannot
tolerate soils if the water does not drain away fairly quickly. A
well-drained soil is usually light or medium, but this is not always
the case and some light soils are very poorly drained.
- Heavy clay.
- Can the plant grow in heavy clay soils?
- Poor soil.
- Can the plant grow in nutritionally poor soils?
- Type of soil the plant prefers. A = acid, N = neutral, B = basic
(alkaline). An entry here does not necessarily mean that a plant can
tolerate the extremes of acidity or alkalinity. For further
information, use the next two fields. An indexed field.
- Can the plant grow in very acid soils?
- Can the plant grow in very alkaline soils?
- Can the plant grow in saline soils.
- How much shade does the plant need? F = full shade (deep woodland,
a north-facing wall etc), S = semi-shade (light woodland, a position
that is shaded for part of the day etc), N = no shade.
- What sort of moisture levels does the plant require? D = dry, M =
moist (this is the average soil type and does not mean a wet soil), We
= wet (or boggy), Wa = water (grows in ponds etc).
- How wind resistant is the plant? M = tolerates maritime exposure, W
= tolerates strong winds but not maritime exposure, N = not wind
tolerant. A blank entry denotes that we have no information.
Information is somewhat lacking and what we have is mainly related to
trees and shrubs.
- Can an established plant tolerate drought ?
- Nitrogen fixer
- Does the plant fix nitrogen from the atmosphere?
- Is the plant noted for providing food etc for our native wildlife?
- Can the plant tolerate atmospheric pollution? (i.e. can it grow in a
large town or city, or by a main road?). Y = Yes, N = No, a blank entry
denotes that we don't know. This question is almost exclusively for
trees and shrubs since these in general have much more difficulty
coping with atmospheric pollution.
- Frost Tender
- Is the plant frost tender?

using any of these plants.
