HELENIUM FALL

Of all late-summer, daisy-flowered perennials, RED
Helenium are among the most colorful. They have
become increasingly popular with the rise of naturalistic
plantings, to which they are well suited, although they
also add a dramatic note to herbaceous borders. The
sturdy stems bear shuttlecock-shaped flowers in fiery
tones of red, orange, and yellow that last for many weeks.
Plants seldom need staking and form slowly spreading
clumps if grown in sun and fertile soil. To lengthen the
flowering season, select a variety of forms, and cut back
some in early summer to promote later flowering.

Centranthus ruber (Red valerian)

or white flowers are borne above foliage
from late spring to fall. Thrives in poor,
exposed sites. H 24–36in (60–90cm),
S 18–24in (45–60cm) or more.
