origin

The girl's eyes (Coreopsis), also called fair-faced or bug flowers, are originally from North and South America. Many of the 115 species are native to the North American prairies, also a large part of the cultivars originated in the USA. As you can easily see on the pretty cup flowers, girls eyes belong to the daisy family (Asteraceae). The genus includes mainly annuals and short-lived perennials, which are known for their abundance of flowers.

Scientific research has shown that the species of the girl's eye are closely related to the one-year bizarre teeth. For this reason, there are always calls to combine both genera under one name. And in fact, the two also look very similar. While Bidens is especially used for balcony plantings, most of the girls' eyes in the bed feel most comfortable.

Appearance and growth

All types and varieties of the girl's eye are characterized by colorful flower baskets, which cover the upright to bushy growing plants over and over - and from June to October. Girl's eyes are real long-term bloomers! Meanwhile, the yellow range of the multi-year girl's eyes has been expanded with new hybrids to a whole color palette of bright cocktail colors - there are now varieties with red, pink, white or reddish brown pile, sometimes filled, sometimes unfilled. A small sensation were varieties that have a red ring on the yellow petals like the one-year-old cultivated dyer's girl's eye (C. tinctoria). The leaves of the girl's eyes are usually very narrow, sometimes pinnate and depending on the type sometimes basic, sometimes spread over the stems.

Most of the varieties of the large-flowered girl's eye but langstieliger and therefore provide the best cut flowers. If you pick them fresh from the garden, keep them in the vase for up to two weeks. In the bed, the golden yellow beacons often provide color for more than eight weeks. Sterile and semi-filled varieties such as 'Early Sunrise' often bloom even more persistently.

Location and ground

Girl eyes love the sun! All species also need a loosely-humorous, nutrient-rich soil and tolerate no waterlogging. In their ancestral homeland in eastern North America, Netzstern's maiden eyes (Coreopsis verticillata) thrive on fairly dry soils. In the garden they are therefore better able to cope with dryness than many of their species. For example, the tallest female eye (Coreopsis tripteris) with a height of up to 1.80 meters prefers a fresh soil on sunny open spaces or on the edge of the wood. Not too dry love it also Lanzettliches and Gro├čbl├╝tiges girl eye.

use

Girl's eyes are among the most popular bedding plants due to their flowering joy. Particularly in demand are the Netzstern girl eyes. They grow bushy upright and work in conjunction with their filigree foliage like flower veils. The warm yellow of the field bloomers underlines the happy mood in the late summer season. A sunshine like the proven variety 'Grandiflora' can be combined with all sun-loving shrubs and flowering shrubs. Especially popular are combinations with other prairie bushes such as Scheinsonnenhut (Echinacea), Sonnenbraut (Helenium) or Sonnenhut (Rudbeckia). As a bedding limit, the compact, only 30 centimeters high 'Zagreb' is often better. If you are looking for a cooler yellow, then you are right with the sulfur yellow 'Moonbeam'. Girl eye varieties with unfilled flowers are popular as an insect willow.

Girl's eyes are easy-care and uncomplicated bloomers. If higher grades threaten to fall apart, they can be loosely tied to a bamboo stick. In the bed, perennial support rings hold kippelige candidates in shape. Compact variants such as the Verticillata variety 'Zagreb' or the densely bushy Lanceolata variety 'Sterntaler' are stable.
Girl's eyes are richly flowering bedding plants, which quickly expired. To rejuvenate them, they are shared like other shrubs after three years at the latest in the spring and replanted in fresh soil.

To cut

If one cuts the Gro├čbl├╝tige and the Lanzettliche girl eye back in the early autumn ground-low, one shortens the flowering time, but promotes the formation of ├ťberwinterungsrosetten. So the plants get through the winter better and live longer. Verticillata varieties will be cut by two-thirds at the beginning of October. In addition, you should trim out withered flower stems continuously, because the seed formation reduces the approach of new flower buds. The best way to do this is to cut off the already withered shoots close to the base. Especially the flowers of half-filled and filled varieties look a little unsightly in the withered state and should therefore be worn for the sake of appearance. Reconstruct some species if cut back strongly at the end of July.

proliferation

Girl eyes can multiply you by division or basal cuttings in the spring. In some species and varieties, especially the short-lived, an increase by sowing is possible.
