Helianthus – Perennial Sunflower

These bold perennials are
so diverse in their habits that it is hoped that the
reader will not come to them with prejudice ‘ because
some of its relatives are coarse and grasping in nature.
Some of the sorts are actually dainty. All the sorts
are tones of golden yellow and they are usually tall
growers. Of the many sorts we shall mention a few of
the best. Helianthus Maximilianii is perhaps
the tallest one, growing 8 feet and sometimes more if
the conditions are favorable. It is the last one to
bloom, flowering as it does in October. Its long stalks
are -full of small golden yellow flowers.

H. orgyalis is sometimes
called the Graceful Sunflower because of its Barrow
foliage which droops. It has single, lemon-yellow flowers
and is another very tall grower.

H. mollis, or the
Hairy Sunflower, grows 4 feet tall and has grayish,
downy, green leaves, dark stems and pale yellow flowers
with dark centers. H. scaberrimus (Woolly Dod)
blooms in September and has deep yellow flowers with
maroon centers. H. decapetalus or H. mulliflorus
one of the most profuse bloomers and, when planted
where it may be given a lot of room to spread, is one
of the good species, but its powers of usurping garden
space eliminates it from the more refined borders. The
Autumn Glory (H. anguslifolius) has created some
comment during the last year. The writer has not seen
it, but has heard that it is one of the most graceful
small flowered sorts, that it makes a splendid addition
to the small number of plants which bloom after frost.

UsEs. These are splendid
to plant in the back rows of the border, in clumps on
the lawn among shrubbery, or to naturalize in the wild
flower gardens or along woodland paths. They combine
attractively with hardy Asters. The flowers are cut
and used for all kinds of decorative purposes.

GENERAL,. Because they grow
so tall, they should be planted in places where the
soil is not only rich, for they are great feeders, but
also very deep. The soil should be manured well every
season, because the roots exhaust the soil of food materials
very readily. They prefer open, sunny places to partially
shady ones, although they like a moist soil. The plants
require almost yearly transplantings.

PROPAGATION. Helianthus is
readily propagated from cuttings or division of the
root stocks.
