The often overlooked plants in the genus Helenium are members of the family Asteraceae and as such sport the ubiquitous daisy-like flowers anywhere from mid June to late autumn, depending upon which of the approximately forty species the plant derives from, and of course, the local climate. Helenium are native to North and Central America and are yet another of our native plants that have achieved fame and acceptance in Europe while being virtually ignored here at home.
The first record of a Helenium species in a European garden was in the late eighteenth century but it was not until the twentieth century that named cultivars started to make their appearance, mostly from European breeders.
Valuable for late summer color in the garden, displaying bright yellows, golds, burgundies and rusts, with prominent, often contrasting central cones. Easily distinguishable from Echinacea (Cone Flowers) and Rudbeckia as their petals are shorter and wider, generally with three points to their 'flattened' ends. The petals are usually held flat or somewhat reflexed signaling many varieties of butterfly to alight for a tasty treat. In the wild Helenium are found growing in moist to wet conditions in sunny meadows and stream banks.
Helenium prefer a moist, but lean, location in full sun. They will resent drying out and will react with chlorotic foliage, poor growth and, often, death. Conversely if their location is too rich in nutrients or constantly damp their growth is likely to be leggy and weak and will require staking. Best success is obtained with adequate moisture and little supplemental feeding. Shearing back young plants in early summer (before the appearance of flower buds) will result in more compact growth, improved branching and an abundance of flowers. Generally speaking plants should bloom for six to eight weeks, and they make excellent cut flowers with a long vase life. Regular deadheading will encourage a longer season of bloom. If happy, plants will form a sizable clump, which can be divided in the spring just after new growth starts. Does not react well to fall division having just spent considerable amounts of energy in flowering.
Commonly referred to as 'Helen's Flower' or Sneezeweed, Helenium are generally in bloom at the same time as the 'raging allergen' Ragweed (Artemisia) and many contend that this coincidence has earned them an unappealing moniker and reputation similar to that of Goldenrod or Solidago. However a more likely explanation is that the foliage was often dried and powered into snuff which was then used to induce sneezing, in an effort to rid the body of evil spirits.
H. 'Double Trouble' PP# 18,206The first double-flowered Helenium to be released and still the only one on the market. Clear bright yellow petals are 3 - 4 rings deep and at least 2” (5 cm) across and in height with a cone the soft golden brown color of honey. In addition, 'Double Trouble' is sterile so there is no energy wasted in seed production, thus there is more energy available for additional flowers. This cultivar will bloom from mid July until frost cuts it down in mid October. A must have plant for many sunny borders. Height: 30” (75 cm). Spread: 15” (35 cm). USDA 4 – 8
H. 'Flammenspiel'Flowers are a clear yellow orange very reminiscent of “Dancing Flames” as the translation of the name suggests. Strong stems support the blooms at a great level for cut flowers and butterflies. Height: 3' (90 cm). Spread: 2' (60 cm). USDA 4 – 8
H. 'Goldlackzwerg'Developed by the famous plantsman Karl Foerster and released in 1949. The English translation of the cultivar name is “Gilded Dwarf” which is very apt. Profusely flowering on strong sturdy stems in August through October. Cones (disc flowers) are chocolate brown while the ray flowers have lovely orange-red petals skimmed at the tips with a gilding of golden yellow. Height: 2'-3' (60 cm – 90 cm). Spread: 1.5' – 2.5' (45cm – 75 cm). USDA 4 – 8.
H. 'Karina' Similar golden yellow blooms to 'Double Trouble' but with single flowers. Again the bright daisy-like flowers are abundant July through October on strong, sturdy stems. Excellent cut flower. Height: 1.5' (50 cm). Spread: 4' (120 cm). USDA 4 – 8
H. 'Moerheim Beauty'The classic of the red flowered Heleniums with highlights of burgundy and gold. Somewhat earlier to bloom (June through August) this selection is another classic for the center of the herbaceous border. Height: 3' (90 cm). Spread: 2' (60 cm). USDA 3 – 9 |
