Description
Nasturtium is a scrambling or trailing annual herb growing
up to 1m.
The flowers are up to 8cm and colouful, ranging from red
to orange to yellow.
Leaves are almost round, deep green and up to 20cm.
It is grown in gardens and allotments as a flower and as a cullinary
herb. All parts of the plant are edible and are added to salads
and stir fries (see http://en.wikipedia.org/wiki/Tropaeolum).
It tastes slightly peppery and a little like Watercress, which is
perhaps why their common name is the Latin name for Watercress.
Nasturtiums are also grown as companion plants, because
they repel pests of cucumber, squashes and brassicas.
They are also grown as trap crops, because they attract blackfly
aphids, perhaps luring them from other crop plants.
