The many blue flowers are carried on smaller branches which are borne all up the top half of the stem, which ends in a small cluster of flowers at the tip. Close up, the small flowers are beautiful with 5 bright blue petals and 5 feathery white scales in the center protecting the stigma and anthers. On sunny days the bees love visiting the flowers. The seeds develop inside little green cups, which are formed by the 5 sepals that have united. Inside each cup three seeds or little nuts turn hard and black as they ripen, usually about a month after flowering.
Every plant produces hundreds of seeds.
In the garden Anchusa capensis is a very easy plant adapting to most soils, surviving on very little water and seeding itself readily. The basic requirements are full sun and well-drained soil. In the western Cape the plants grow during the wet winters and flower in late spring and early summer. If Anchusa capensis receives no water during the summer it dies after forming seed. This germinates freely the next winter.
