Hybrid Helena

Helium hybrids, Helenium X, are perennial plants belonging to the familyAsteraceae, such as asters, daisies or daisies. These are horticultural accessions, often multi-generational blends of Helenium autumnal and Helenium nufiflorum, species native to North America. The breeders have produced about a hundred cultivars with warm and varied colors, with a more rigid hold, and which are generally a little less high than the botanical species. Hybrid Helenius bloom in summer and autumn. They are solid plants with long blooms.

Hybrid Helena

Description of Hybrid Helenius

The helenium x are deciduous perennials. Each year new stems emerge from a dense stump, 40 to 60 cm wide. Depending on the variety, the stems rise from 60 cm to 1.50 m and bloom from July to October. The stems ramify to form several daisy-shaped flower heads with dark, bouncy hearts and bright colored ligules. Some flower heads are flat and regular, while others frilly, or curl down like small skirts.

How to choose hybrid varieties?

The colors of the hybrid helenies are warm: bright yellow, ocher, orange, red, pink, burgundy … or even two-colored. The massifs will be all the more pleasant if several colors are associated. It will be necessary for example, to pay attention to the dark colors, like Hélénie ‘Rubinzwerg’ or ‘Ruby Tuesday’, very beautiful, but which ask to be enlightened by bright reds or oranges.

You will make your choice so looking at the color, but also the height of the plants. On the other hand, some are more precocious than others:

  • Helenium ‘Moerheim Beauty’, copper red, 1 m tall, flowers from July to October
  • Helenium x ‘Mardi Gras’ is only 50 cm tall in sulfur orange. It blooms from July.
  • Helenium ‘Waltraut’, in August, regular and yellow flowers picking orange. 90 cm.
  • Helenium ‘Rubinzwerg’, flower in bright red skirt, from July until the end of September.90 cm
  • Helium ‘Flamenco’, a two-tone yellow and red August and September, 120 cm high
  • Helenium ‘Hollwege’, very high, rather red then turns to other. Flowered from August to September.
  • Helenium ‘Rubinkuppel’, orange ligules with darker back. 1m high.
  • Helenium ‘Little Orange’. Bright and compact orange. 70 cm.
  • Helenium ‘Kaniara’, bright yellow with a big green heart. Solid rods of 120 cm.

How to cultivate Helenium x hybridum  ?

Hybrid helenias require a neutral to the basic soil, rich and well-drained, but does not dry excessively in summer. They are installed in the garden preferably in the spring with a small contribution of compost. They are robust and easy plants.

Given their height, and their high stalks sometimes sprawl a little, they are rather adapted to the bottom or the middle of the massif.

If your hull, a little high, collapses too much to your taste, you can surround it with other perennials, the stake, or also the one-third toast in July: its flowering will be a little delayed, but it will then be lower.

To remove the defused heads if the variety is not sterile, generally allows to prolong the flowering.

At the end of winter, the stump is rid of its old stems. After 5 to 6 years, becoming less floriferous, hybrid helenia gains to be broken up in several divisions , and nourished by a new contribution of compost.

How to multiply the hybrid helenies?

The hélénies hybrids do not reproduce by seeds. Not only are some of these hybrids sterile or produce very few seeds, but moreover, if seed is produced, their offspring are rarely faithful in color.

To propagate your favorite helena, you will need to either divide it or cut it . The cuttings succeed very easily with the base of the stems (15-20 cm) planted in pots and kept in nursery their first winter.

The divisions are made in the spring, while news is emerging, but it does not really freeze anymore.
