The hybrid chrysanthemums
With the name chrysanthemum the flowers of the genus chrysanthemum that bloom in autumn are usually indicated; these are hybrid species, selected for the beauty or the size of the flowers; their diffusion is instead due precisely to the autumn flowering, given that in Italy they are the flowers traditionally used as a gift for the dead, whose feast falls in November. In particular the chrysanthemums that we can find flowered for the recurrence of the dead are hybrids obtained from the crossing of two species, the Chrysanthemum moriifolium and the c. indicum. Over the decades various varieties have been obtained, with very small flowers, a few centimeters in diameter, and also with enormous flowers, up to 25-30 cm wide, with 5-10 petals or with hundreds of perfumed, colored petals lit, of soft and delicate colors, variegated and mottled. Besides the beauty of the cut flower and the very interesting flowering period, the hybrid chrysanthemums also offer the advantage of being easy to cultivate and perennial; a beautiful head easily finds space in the flowerbeds of the garden, where it can give us color in the gray weeks of October and November.
The hybrid species of chrysanthemum are mostly perennial; they develop a beautiful bush of dark green, or silvery green, with erect stems, poorly branched, which bear large lobed leaves, slightly leathery to the touch and rough. The buds develop towards the end of summer and bloom in autumn, for a few weeks. They prefer very sunny positions and need regular watering, every 12-15 days, more often if the climate is dry; in spring it spreads around the slow release granular fertilizer plants, repeating the operation every 4-6 months.
Chrysanthemum garden species produce buds at the apex of erect, poorly branched stems; there are species with very large flowers, in order to obtain the flowering it is often necessary to provide a guardian with the stems that bear the buds, to prevent the wind or the weather from bending them.
Every 4-5 years the tuft is rejuvenated by uprooting it and dividing it into some smaller tufts, using in particular the most fleshy and lush stems.
After flowering it favors the compact and dense growth of the head of chrysanthemums cutting all the stems to about one third of their height. We also remember to always remove the withered flowers, to avoid favoring the development of mold and rot.
Some chrysanthemums are annual, and bloom in spring or autumn; these plants are sown directly at home.
Chrysanthemum - Chrysanthemum: Not just chrysanthemums
The genus chrysanthemum includes dozens of species of shrubs, perennials and annuals, all producing large white, yellow or pink flowers; in fact the many species of daisies, the pyrethrum, some species of September, belong to the chrysanthemum family.
They are always flowers gathered in flower heads, made up of small flowers without petals, which give rise to the central part of the flower head, often golden in color; on the outside of the head there are flowers with one or more petals, in the classic daisy these little flowers have only one elongated petal, white in color.
All these chrysanthemum plants are of European or Asian origin, and can easily find a place in the garden, they do not fear the winter cold and the summer heat.
