Large-leaved aster (lat. Aster macrophyllus) - flowering culture; a representative of the numerous genus Astra of the Asteraceae family, or Astrovye. Under natural conditions, the species under consideration grows in light forest zones in Canada and the northwestern regions of the United States of America. The species is rarely used in ornamental gardening, although it is unpretentious.
Characteristics of culture
Large-leaved aster is represented by perennial herbaceous plants, not exceeding 1 m in height, equipped with elongated thick rhizomes and rather dense, erect, pubescent, strongly branching stems at the top, sometimes bending and falling to the surface of the earth. Stems have foliage of two types: basal - dentate, ovoid, pointed, petiolate foliage, the length of which varies from 10 to 14 cm; and lanceolate or broadly lanceolate, rough to the touch, green, petiolate. The petioles of the foliage are purple or purple in color.
Inflorescences - baskets, as a rule, reach a diameter of 2-3 cm, are presented in huge numbers, apical or corymbose inflorescences are collected. Baskets are composed of marginal purple, lilac or lavender flowers and disc yellow or dark yellow flowers. The inflorescences are equipped with a three- or four-row wrapper. Blossoming of large-leaved asters is observed at the end of summer, lasts up to 2, 5 months, that is, until the onset of stable frosts. The species in question is not too picky about growing conditions, easily tolerates frosts down to -40C even without additional shelter, and is resistant to pests and diseases.
And despite these excellent properties, the species is rarely used in gardening. The fact is that in the process of growth, the large-leaved aster falls apart on one side, respectively, such a composition looks deplorable. But some gardeners and florists have found an approach to this plant. To maintain the bushes of the species in question in perfect condition, it is necessary to select the right allies for them. And we are talking not only about the representatives of the Astra genus, but also about other flower cultures.
Large-leaved aster goes well with many plants, including reed grass, astilbe, sage, daisies, aconites, blueheads, stonecrop, spikelet, goldenrod, etc. Plants also feel good in the company with Pyrenean aster, heather atra, New England aster, aster New Belgian, etc. As mentioned, the large-leaved aster is a late flowering crop, the first inflorescences-baskets are formed at the end of summer, which means that the plant is ideal for creating gardens of autumn flowers (or, as they are also called, automnals.
Growing features
Large-leaved aster does not belong to the category of light-loving crops; for normal development, it requires shady areas with moderately fertile, moist and loose soil. Otherwise, the culture is undemanding. Large-leaved aster propagates by seeds and dividing the bush. The second method is the most popular. This procedure is carried out every 3-5 years, for this the bush is dug up and divided into several parts. Some gardeners do it a different way: they sharpen a shovel and separate part of the bush without removing it from the soil. It is important to remember that each section should have roots and a kidney, then they will quickly get used to a new place and will actively grow.
Large-leaved aster develops with lightning speed, and quickly fills empty areas, so the division of the bush should be carried out regularly. In addition, this approach will support the decorative effect of the bushes. When planting divisions in a new place, the soil is dug up, shallow holes are made, some of which are filled with a mixture made up of garden soil, compost or humus and complete mineral fertilizer. Crop care comes down to the simplest procedures: watering with warm water, removing weeds, loosening, fighting pests and diseases.
