A well-known annual, at one remove from the wild
Blue-bottle of the cornfields. Its growth is slender,
the leaves grey-ish green, the flowers double,
with a rough hairy calyx, in several shades of
blue – one a distinctive and charming light

should be sown at the end of March in patches,

from self-sown seeds, and in such situations it
may be sown in August to stand the winter and
flower early in the following summer.
