Derivation of name and historical aspects
History
Heliophila means sun loving. In South Africa there are 71 species of Heliophila most of them annuals naturally growing throughout Namaqualand and the south western Cape. Although many of them are similar to Heliophila coronopifolia with blue flowers, there are also species with pink and white flowers.
The Showy Sunflax belongs to the mustard family (Brassicaceae), as do cauliflowers and broccoli. In this family the plants often taste and smell of mustard and sulphur. If you crush a sunflax, it smells like a cauliflower.
Growing Heliophila coronopifolia
Grow
In spite of their fragile appearance these little annuals have adapted to grow and flower abundantly in areas known for their heat and drought. Surviving the long dry summer as seeds, they germinate with the autumn rains, which is also the time to sow them. The seed can be scattered directly into garden beds or first sown in seed beds or seed trays. They should be planted out as soon as they are big enough to handle. The seed germinates well, usually within a week. The plants are easy to grow in the garden. They grow fast given the right conditions of full sun, well-drained soil and regular watering during the growing season. Heliophila look beautiful planted densely, giving a mass of blue, or they can be interspersed between other annuals, bulbs or shrubs.
