Coreopsis flowers

Coreopsis (Coreopsis) – a genus of flowering annual and perennial herbs , less often subshrubs and shrubs from the Compositae family. Most species in nature grow in dry places and on roadsides in North, less often South America. Used in ornamental gardening, where they are valued for long flowering and unpretentiousness.

  • Rhizome: roots are fibrous.
  • Stem: upright, branching.
  • Leaves: dissected or whole.
  • Fruit: flat dry achene.
  • Reproductive ability: seed reproduction, for perennials – division.
  • Illumination: photophilous.
  • Watering: in dry weather.
  • Content temperature: frost-resistant perennials.
  • Flowering time: June to autumn.

General description of coreopsis and its photo

The genus includes about 100 annual and perennial species, differing in growing conditions, size and color of flowers, most of which are rhizomatous herbaceous plants with numerous branching erect shoots. The height of the stems varies from 20 to 110 cm. The basal rosette leaves are large, entire, the stem leaves are opposite, pinnately dissected or palmately divided, with linear lobes.

Coreopsis flower in the photo

Coriopsis flowers bloom at the ends of elastic long peduncles, they are baskets up to 8 cm in diameter, simple or double. Their color can be yellow of various shades, pink, brown, red or purple. Each individual coriopsis flower consists of jagged petals located along the edge, representing barren reed flowers, and a disc of bisexual tubular flowers, most often darkly colored.

The culture blooms profusely and for a long time, usually from the end of June – the beginning of July until the very frost. The fruits ripening at the end of summer are oblong-flat dry achenes, black with a small yellow spot at the point of germination, shiny, small – 1 g can contain up to 500 pcs. Seeds crumble easily, giving self-sowing, so they are harvested in several periods. Germination is maintained for 2-3 years.

Due to the shape of the seeds, reminiscent of bugs, the flower got its scientific name “coreopsis”, which in Greek means “like a bug.” Sometimes in the literature there is another name for the culture, calliopsis (Calliopsis). The people also call it lenok, “girl’s eyes”, brown eyes, “Paris beauty”, yellow chamomile.

Coreopsis is native to the Americas. About 30 species are found in North America, some in Central and South America, a small part grows in Africa and the Hawaiian Islands. About 30 species are found in North America, some in Central and South America, a small part grows in Africa and the Hawaiian Islands.

About 10-15 species of annual and perennial coreopsis are most common in cultivation. All of them are valued for long and abundant flowering, combined with a spectacular appearance, unpretentiousness, ease of care and reproduction. Their advantages include durability in cutting. Flowers in a vase can live for more than a week, so the plant is often used in floristry.

Tall species and varieties of coreopsis can decorate the background of a flower garden, are used for group plantings on lawns, and perfectly decorate the south side of fences and bushes. Low-growing varieties are so viable that they tolerate transplanting even during flowering. These unpretentious and drought-resistant plants look good in borders and flower beds, and can also grow in containers, on balconies and loggias. For container culture, the depth of flowerpots and balcony boxes should be at least 20 cm.

Below are the most decorative types of coreopsis, photos and descriptions of some common varieties.

Decorative species and varieties of annual coreopsis

Coreopsis dye (C. tinctora) is the most famous and widely used species in floriculture. At the ends of its branching shoots, thin and at the same time strong, single inflorescences bloom, baskets 3-5 cm in diameter. Reed flowers can be yellow, orange, red or dark purple. Tubular flowers are usually dark. Most of the leaves have a doubly pinnately divided shape and are concentrated in the basal rosette, while in the upper part of the stems the leaves are entire, oppositely located. Flowering is plentiful and long, begins in June and ends with the onset of autumn cold.

There are tall (up to 100 cm) and low (20-30 cm) garden forms.

On sale you can find the following varieties:

Coreopsis ferulifolia, or bidens ferulifolia (C. ferulifolia, Bidens ferulifolia) – so far a little common, but very attractive species. A plant up to 90 cm high has strong stems branching from the ground itself, from early summer to autumn covered with many bright yellow inflorescences-baskets with a diameter of 2 to 4 cm. Bushes and dark green, strongly dissected, openwork leaves are very decorated.

Created several garden forms:

Decorative species and varieties of perennial coreopsis

Coreopsis large-flowered (C. grandiflora) , the most common yellow coreopsis in floriculture.

Varieties of which have now supplanted the previously popular perennial species:

lanceolate (C. lanceolata) ,

eared (C. auriculata) .

The height of the bush is from 30 to 100 cm, the shoots are strong, straight, strongly branched, covered with opposite, almost sessile leaves, pinnately dissected in the upper and entire in the lower part of the stem. Inflorescences are large, up to 8 cm in size, in the form of baskets with golden yellow outer reed and dark yellow inner tubular flowers, appear at the ends of continuously growing shoots from July to late autumn. Culture belongs to the category of juveniles, needs to be updated every 3 years.

Among the many varieties, the most popular are:

Baden Gold is an early flowering coreopsis up to 90 cm high, with inflorescences up to 6.5 cm in diameter, appearing as early as June.

Of the terry coreopsis, compact (up to 50 cm) varieties Sunray and Airlie Sunrise, as well as dwarf (20-30 cm) Sandancer, can be noted.

Whorled coreopsis (C. verticallata) is rare in our flower beds, although it is no less beautiful than the previous species, and it is also much more durable, it can grow without a transplant for up to 6 years. It is a highly branched bush 40-60 cm high, with sessile light green leaves, dissected into very narrow, needle-like lobes and collected in whorls along the entire length of the stem. Openwork foliage gives the plant a decorative effect throughout the growing season. Flowering lasts 60-70 days, from June to August. The inflorescences of coreopsis whorled (see photo below) are somewhat different in shape from the previously described species, they look like star-shaped baskets up to 3 cm in diameter with narrow light yellow petals – reed flowers and a yellow center of small tubular flowers.

There is a large-flowered form (C. verticallata f. grandiflora) , which is distinguished by the large size of both the bush (up to 80 cm) and inflorescences (up to 6 cm), besides, it blooms more abundantly than the natural species.

Zagreb , about 40 cm high, golden in color with a dark center.

Child of the sun , grows up to 30 cm, with golden yellow petals, colored with single red splashes.

Coreopsis lanceolate (C. lanceolata) is distinguished by petiolate lanceolate or almost linear leaves, concentrated mostly at the bottom of the stems, almost disappearing towards their top.
