Growing Wild Daisies for
Wildlife

Are you bored with
begonias, fed up with fuchsias or tired of tagetes? If so, just
look to our native plants for inspiration and something a little
different. Wildflower gardening becomes ever more fashionable and
not only offers us some much needed variety but by planting native
species we can ensure that our gardens will be well used by
wildlife. The wild daisies, or Compositae family, have already
come under our scrutiny but there are plenty more valuable plants
that did not feature in our last round up of this useful family.
The daisy family are amongst the most highly evolved of our native
flora, making them very successful and ubiquitous plants. Their
flower structure consists of many tiny flowers or florets
clustered into larger flower heads and the dandelion shows
this
structure perfectly. This means that they have masses of pollen
and nectar on offer to bees and butterflies plus large quantities
of seeds too. If your garden or allotment is visited by
greenfinches and goldfinches (or linnets if you are in a more
rural location) you will know how important these flowers are to
seed-eating birds. Dandelion clocks have their uses and the
stunning white ermine moth’s caterpillars feed on dandelion
leaves. |

We have already explored the more
familiar daisies (the May edition of OG) including ox-eye daisy,
lawn daisy, corn chamomile, corn marigold and fleabane, but there
are so many more to add colour to your garden. There are bright
yellow natives for meadows, thistles for spectacular height or if
you prefer there are the ‘wilder’ varieties of introduced plants
such as Michaelmas daisy and golden rod. All daisy family and all
brilliant plants for wildlife. For
the purist though the natives will take precedence and there is no
better place to start than the statuesque hemp agrimony
(Eupatorium cannabinum). Butterflies have an affinity with this
family and this tall, pink-flowered species attracts small
tortoiseshells like a magnet. It is also the larval food plant of
the little lime speck pug moth. This is very much a waterside
plant in the wild although it will be perfectly happy in a dense
clay soil in a border. It germinates fairly easily but
sporadically from a spring sowing, but if you do try this species
from seed, make sure that the compost doesn’t dry out at any
stage. Perfect for a bog garden or the back of a wide border,
hemp agrimony will reward you with a steady stream of butterflies
and bees of all kinds, well into late summer when colour is fading
elsewhere. |

There are other native daisies for
damp spots and sneezewort (Achillea ptarmica) is pretty and
obliging. Its cultivated cousin, A. ptarmica The Pearl, is a
commonly grown variety of the wildling, but being a double
flowered form it has no nectar and very little pollen. Sneezewort
will be happy beside a pond in damp soil, in a wildflower bog
garden or in a heavy clay soil, where its white flowers will
wander through other plants or grasses. Indeed it is a useful
component of a damp wildflower meadow and can be added to an
existing grassy area as long as the soil retains moisture. Bees
will visit this plant for pollen. It is closely related to yarrow
(Achillea millefolium) a common plant on roadsides and in lawns
and is an important component of many wildflower meadows where it
attracts meadow butterflies. This plant is an unassuming and
often overlooked wildflower but has great wildlife value. Both
butterflies and bees visit it steadily through its long flowering
season – not in great quantities but it is reliable and pretty.
The usual flower colour of its small daisy clusters is a rather
dirty white, but it sometimes naturally appears in a pale pink
form which is well worth growing, or try the
brighter cultivated varieties. |

Plant breeders have taken advantage
of this colour variation and the humble yarrow now appears in a
huge variety of pinks, reds and oranges. They can spread quite
quickly, but are remarkably hardy and easy-to-grow plants. These
coloured forms will attract butterflies
and bees but do not seem to have quite
the wildlife attraction of the wild plant.
Thet are however a great addition to a cottage style border. |

Wildflower meadows are rapidly
becoming must-have additions to even the smallest of gardens and
the daisy family plays a large part in their composition. There
is a bewildering range (to the untrained eye) of yellow
‘dandelions’ including the hawkweeds, hawksbeards, hawkbits and
cat’s ears. By and large these can be quickly distinguished from
the true dandelion by their taller size and the fact that they
usually have several flowers on branched stalks. The appearance
of their flowers is less coarse than the dandelion and indeed the
small mouse-ear hawkweed (Pilosella officinarum) is stunning. Its
flowers are a delicate shade of lemon yellow and the gently
creeping stems and leaves are covered with silvery hairs. This is
a wonderful little plant for the front of a border or short
grass. The hawkweeds and hawkbits come in many species, most
practically indistinguishable from each other, but the commoner
species will often be found in mixtures of seed for establishing a
meadow. They provide a splash of bright colour in both spring and
autumn (depending on the species) but are best confined to grass
as they seed freely. One exception is the orange hawkweed (Hieracium
aurantiacum), which is often known as fox-and cubs. This plant
was once commonly grown in cottage gardens and is not a true
native, but is naturalised in some areas. Like the mouse-ear
hawkweed it will creep about at the front of a border, displaying
its burnt orange flowers on slender stems. |

Yellow is a common colour amongst the
members of the Compositae and tansy (Tanacetum vulgare) is another
well-known favourite. This plant has the potential to be
invasive, reaching a meter and a half in height, and is best grown
only in a wilder part of the garden. However it attracts plenty
of hoverflies to its bright yellow button flowers and is easy to
propagate from rooted stem pieces.
If dramatic plants excite you then
look no further than the scotch thistle (Onopordum acanthium).
This native may crop up in unexpected places as the seed is long
lived, but before you plant, make quite sure you have the space.
It can reach dizzying heights – maybe three meters – and the basal
leaves are prickly and huge but pleasantly woolly. The purple
thistle flowers attract many bees and butterflies and birds such
as goldfinches will tease out the seeds in the autumn. A giant of
a plant but well worth growing if you have the space. |

As usual not all of this wildlife
attracting family should be included in the garden – even in the
largest of plots - ragwort being the obvious contender. Coltsfoot
too, in spite of its pretty late winter flowers that remind us the
spring is around the corner, is wildly invasive as are the
butterburs. But others not yet mentioned including the glorious
blue chicory, wormwood for its grey foliage and some of the
non-invasive thistles (melancholy thistle is worth growing for its
name alone!) could be perfect if the right spot is found for
them. Experiment with our daisies and you may be surprised by
their versatility and wildlife pulling power. |
