Helenium
Ask anyone if he knows sneezeweed and
chances are that he can't place it. But tell himabout the splendid
helenium or helensflower you had last fall and you have his sympathetic
ear.
Yet few appreciate its true value for
gardens acid for cutting. Like quite a few other flowers native to
North America, it is held with higher esteem abroad than in its native
country.
Give the plants a sunny, well-drained
position, and they'll develop into good-sized clumps 3 to 6 feet high
depending upon the species or variety planted.
Any good garden soil is suited to their
culture, and where conditions are congenial, they not only last for
years but increase by forming new, vigorous crowns all around the
original mother plants: English gardeners who give it a foremost place
among the hardy fall-flowering perennials water the plants at 10-day
intervals with a solution of 1/2 ounce sulfate of potash in 1 gallon
of water: This prevents the flower petals from drooping. In some sections
a little black-snout beetle goes after the growing tips and young
flower buds. Repeated spraying with a contact insecticide to which
has been added a little nicotine sulfate to serve as a repellent keeps
these pesky little creatures in check.
Once planted, helenium may remain for
several years in the same position. Though well satisfied with average
soil fertility, they respond freely to good treatment. A little complete
plant food worked around the plants, as new spring growth gets under
way is very helpful. Dividing and replanting in spring may become
essential every third year to rejuvenate the clumps. Set the crowns
even with the soil level and firm the roots well. Follow with a good
watering, and the plants will continue to grow without any further
attention.
Staking the taller sorts is essential,
despite the fact that the stems are woody. Use several stakes about
one-half the total height of the plants so that the tops can sway
freely.
American gardeners prefer the variety
Moerheimi Beauty because the bronzy red ray petals shading to orange
at the tips are strikingly different from any other flowers that share
its blooming season in August and September: The compact habit allows
us to enjoy the flowers by looking down upon the 2- to 3-foot plants.
Autumnale rubrum, bronzy
red, and Autumnale superbum, sunflower-yellow, are
taller favorites for the background,
Riverton Beauty is an early fall bloomer
4 feet tall. The flowers are unique in color in that they combine
lemon-yellow ray petals, with a black center. Riverton Gem bears old
gold and terra cotta flowers, which change to a stunning wallflower
red.
