Amsonia Tabernaemontana | Blue Star *

Amsonia tabernaemontana (Blue Star) – a herbaceous plant whose height in adulthood reaches 80-100 cm. It blooms in May-June, forming flowers in the form of small stars.

Amsonia tabernaemontana surprises everyone twice a season: in early summer, when it brings to the compositions a purely blue color inherent in few flowers, and in autumn when the bush becomes like a yellow blazing fire.

A distinctive feature of the plant is also a fairly powerful root, woody with age. In addition, Amsonia tabernaemontana willow has arcuate stems, and young spring shoots have a purple color. The stems are covered with regular, shiny and rather narrow leaves. Their shape is very similar to the shape of willow leaves, due to which these subspecies, in fact, got their name.

The color of the leaves is grayish-green. But after the first frosts descend to the ground in the fall, the leaf changes color to yellow-orange – at this time the plant is very decorative.

The bluish-colored florets have five petals and a star-shaped shape. The shape of the inflorescence is raceme-shaped, and the inflorescence themselves crown the tops of the shoots. In this case, the blue color is found in many shades, which directly depend on the shape of the flower and its variety. By the way, Americans – and the birthplace of this Amsonia tabernaemontana is the United States – call this flower Blue Star, literally – Blue Star.

Cultivation and care

For successful cultivation of Amsonia tabernaemontana, it is necessary to choose a sunny place of growth for it, although even a small shading will not prevent the plant from fully developing and decorating your garden.

Reproduction

Reproduction of Amsonia tabernaemontana occurs with the help of seeds and due to the division of the bush. If you decide to propagate the plant with seeds, sowing is best done exclusively for the winter, so that the seeds have time to go through the process of cold stratification for 4-6 weeks, and the day before sowing they should be soaked. When sowing, lightly sprinkle the seeds with earth in a layer of 1-1.5 cm.

If you prefer the method associated with the division of the bush, it is better to deal with it exclusively in the fall.
