Echium Wildpretii ( Echium wildpretii ), rare also Tajinaste is a species in the genus snake heads ( Echium ) within the family of the Boraginaceae (Boraginaceae). The species epithet honors the Swiss gardener and botanist Hermann Wildpret .
description
Wildprets Natternkopf is a perennial ( hapaxanthe ) plant that reaches heights of up to three meters. The base rosette , which can be up to a meter in diameter and consists of linear-lanceolate leaves, is characteristic of this type of adder head . The base rosette sits firmly on the ground with a short, unbranched trunk, the leaves are about 30 × 2 cm in size, are densely covered on both sides with relatively soft bristles and are therefore white-felted and rough. A single, narrow, conical inflorescence rises from the center of the rosette and is densely covered with innumerable flowers . Depending on the subspecies, the color of the flowers is red or pink, they finally turn blue. The broad, funnel-shaped flowers are between 10 and 14 mm long. The fruits are small nuts that are rough to the touch.
The flowering period extends from May to August.
