Does the Echium plant (Pininana - type) die after flowering or is it a true perrenial/bienial?
asked in Plants
It is biennial and occaisionally triennial if struggling. It forms rosettes of leaves up to 1m (3') across, the leaves being a little rough to the touch due to the fine sharp hairs. About August or September the plants which are going to flower that year begin to grow quickly in the centre of the rosette of foliage and the flower stem develops quickly.The flowers are blue or pinkish purple, depending on the seedline and the soil conditions. (it will cross with E. wildprettii or E. simplex)
