Astilbe

The astilbe history of the plant

The name astilbe comes from the Greek. The plant has an insignificant appearance given by the tiny corollas emitted by the astilbe. Tiny and insignificant corollas if taken alone one by one, but of great beauty if considered in the whole of the inflorescence in the shape of a feathery spike, in shades of intense and luminous color, of great effect and relief against the green background. To get the most out of this species it is always good to plant them in groups of at least five or six specimens. Both in one color and in an assortment of colors. The astilbe genus includes a dozen perennial herbaceous species from Asia and North America. There are also various hybrids of astilbe of horticultural origin, widely spread in the garden or on the balcony.

Astilbe: transplant sowing and multiplication


For a certain period between 1800 and 1900 the astilbe plants were renamed with the name of spiraea barbata but it was a gross error on the part of the botanists of the time because the true spiraee are completely different. Astilbe are sturdy, low-need plants that love shade and constantly moist but not too waterlogged soil. These are plants that can resist the winter cold well and that, by virtue of these qualities, are able to solve problems in soils rich in vegetation, where there are corners completely sheltered by trees with all the characteristics of the undergrowth. The plantation of the astilbe is carried out at the end of winter, in a soil of leaves mixed with a little sand. This mixture is placed at the bottom of the planting hole or in the pot, then the specimens are planted.

Astilbe: watering and fertilizing


The propagation of astilbe plants is done in a simple way by dividing the tufts in spring. A tip that should not be overlooked when forming new leaves is to start fertilizing, two or three times a month, using a liquid fertilizer. As soon as the inflorescences lose freshness, it is better to cut the stems, very low, to cause the formation of new buds. The feathery inflorescences of these generous plants are also of good effect as a cut flower and lend themselves to composing showy and elegant bouquets, perhaps in combination with bluebells, snapdragons or gladioli. Astilbe can also be grown in pots at least 25 centimeters deep with fertilized soil. Furthermore, the earth, even in pots, must always be kept fresh especially when it does not rain outside.

The astilbe the feather flower


Astilbe also known as the feather flower, in the language of plants symbolizes exteriority. Among the most decorative astilbe are the astilbe astilboides which is of Japanese origin, has finely engraved leaves and produces white flowers, in June. The astilbe davidii comes from China and its appearance is truly majestic when it emits the tall red spikes, more than half a meter long. The maximum flowering occurs between June and July. Astilbe japonica is a very common species commonly called silver plume due to the swollen white ears. Astilbe lemoinei is in all likelihood a hybrid, it blooms between May and June with very elegantly shaped spikes in various shades of red and pink, as well as a pure white variety. L’ astilbe thunbergii is a very precocious species which begins to bloom as early as the beginning of May. Its inflorescences are quite small and white.
