What is a weed? It is a wild plant that bother you, because it grows and
reproduces aggressively. Often the plant may stay on
the places in the garden, where they don't bother other plants. I also can enjoy of these plants. There are a number of species which are very popular in insects.
Nettle is a host of different caterpillars of beautiful butterflies.
Some wild plants have their own place in the garden and are listed in the page

A species with many names. When you crush the leaves, they smell like
garlic, but it is not related to garlic. (glucoside sinigrine) The flowers
are visited by bees and hover flies. Plants are often found growing along
the edge of forests. In our garden they grow very well. On a few

Hay Fever Weed (Ambrosia artemisiifolia). Family compositae (Asteraceae).
Sun, moderately rich to rich soil. Flowering Time: IX - X.
An annual plant native plants in the Netherlands. The plant is unisexual.
It is a major cause of hay fever. Because it blooms late, the period that
people suffer will be longer. There are two other species in the
Netherlands. Namely Cuman ragweed, Perennial ragweed or Western
ragweed (Ambrosia psilostachya) and Buffalo

Bindweed, or Rutland beauty (Calystegia sepium). Family
Convolvulaceae. Bloom time: Vl - lX.
It isgardenweed. It twines around the garden
plants. But the flowers are beautiful, so at
some places I let it grow. It can reach a height of 3 m. It is difficult
to remove because of the system of branched rhizomes. It prefers moist soil and grows towards the sun.

Amaranth family (Amaranthaceae). Annual. Bloomtime VI - X.
The shape of the leaves is variable: Oblong, oval, diamond-shaped with a smooth or
toothed edge. The leaves are green, but they look grey green because of whitish crystals. Clusters of small flowers. The seeds (nuts) contain
oil and were used for making bread. The leaves taste like spinach, but contain more oxalic
acid so you can't eat too much.
It grows well in rich soil. In our garden is not a problem. You can easily pull it out.

In spring there appear fertile, light brown, cone-bearing stems.
They are unbranched. Sterile stems start to grow
after the fertile stems have wilted. (after about two weeks) The stem
has whorls of long branches, with rounded ridges.
Every year there are some plants in our garden, but they don't give
trouble. Because of the many ferns they don't get much light. The soil is
rather dry. It prefers moist soil.
It can be very difficult to control. You have to remove the plants
before they have spores. But the reproduction also is by the roots.
The roots are tuber-bearing and rhizomatous.

Small Horsetail, dwarf scouringrush
(Equisetum scirpoides). Origin: North America.
I put it on this page, though I bought it. I have many regrets. I had
planted the horsetail near the pond. But in short time, it had spread to
other parts of the garden and formed a dense mat. The roots are tiny, fibrous rhizomes that are
impossible to pull out completely. In the (small) rock garden I had to
remove all stones to get rid of it.
The garden centers should place a warning because of its invasiveness.

But now it has been naturalized over almost the whole of Europe and
parts of America, North Africa, Australia, New Zealand. (Escaped from the
gardens) Sometimes you can find it at a garden nursery (in the
Netherlands). The plant grows on walls and rocks, where it root in the
cracks in the rocks. The creeping stems root at the nodes. The flower
moves after fertilization away from the light and buries the seed between
the stones. In the wall pot I like Ivy-leaved Toadflax very much.

- IX. A perennial herbaceous plant. Height about 50-90 cm.
I like them at some spots in the garden.
It has a short, knotted rhizome. Hence the name knotted figwort. The
scientific affix 'nodoso' relates also to the roots.
It prefers damp and shady places. Loamy, fertile soil. The plant
has an erect, square, hairless stem with leaves in opposing positions. The
small flowers are visited by wasps and bees. These flowers have green
lower lips and purple upper lips.
Common figwort was used in medicine to treat skin complaints.

Bloom time: Vll- X.
This is a biennial weed, but it is beautiful in the garden and you can find
many insects on the flowers. It starts to bloom around St-Jacob (July 25)
The alkaloids in the plant are poisonous especially to horses, but also to other
animals. Normaly it is not eaten by animals, but the alkaloids remains in hay.
There are no meadows near my garden and I only have two plants.
The place where it appears, is a surprise. The plant favours well-drained soils
but will grow in most ground conditions. A dense grass sward provides less of an
opportunity for the seeds to germinate. They are spread by the wind.

Dandelion, common dandelion, lion's tooth, blowball (Taraxacum
Aster family (Asteraceae or Compositae).
From half April. Perennial.
Dandelion has long, lance-shaped leaves. That's why it got in Old French
the name "Dent-de-lion" (means lion's tooth). Rabbits, horses and many other animals likes dandelions. Because of the
long taproot, they are difficult to remove. It
will regenerate, when you don't remove the taproots completely. When the flowers
appear, I try to remove them all out of the
lawn. The leaves form a rosette can't be killed by mowing Each flower heads consist many tiny ray flowers. There
are no disk flowers. To spread in the wind, the seed has a kind of
parachute. I've read there are
many species of dandelion. But they are very similar.
Dandelion contains homeopathic substances (bitter compounds) to
improve gal and liver functioning. From the latex rubber can be
made. In the Second World War the Soviet Union made rubber extracted from
a Russian dandelion. Now there are experiments again with the Russian
