Matthiola incana is part of the Brassicaceae family of plants. It is also known as Matthiola incana ‘Brompton’, Matthiola arborescens, Hoary Stock, Stock, Brompton Stock, Cluster-leaved Stock, Gilliflower, Common Stock, Wallflower Stock, Queen’s Stock or Hopes. Matthiola incana is a short-lived perennial. They usually grow it as a biennial.
It has narrow green leaves. And it has fragrant flowers. It prefers calcareous soil. That is why they grow on cliffs by the sea. Matthiola incana is native to Southern Europe.
I really like this flower due to its fragrance. They usually sell Matthiola incana in farmer’s markets in California. There is a farmer’s market every Sunday near me in Los Angeles that usually has these flowers. When I see it I buy it. I like them as they are very colorful and fragrant as cut flowers and last long. However, if you buy them, change the water often as they muddy the water fast.
Matthiola incana colors range from white, cream, yellow to pinks, mauves, lilac, purple, and burgundy. The spikes of flowers grow on tall stems. It flowers in late spring and summer. It grows to about 30cm or 12in. It is woody at the base.
How to grow Matthiola incana:
Grow Matthiola incana in the sun. Plant it in well drained soil and in a sheltered location. Propagate them from seed sown in early spring. You can cut them back after the flowers are done. Watch for aphids, flea beetles, cabbage root fly as well as downy mildew, clubroot or root rot.
Double-flowered Stocks are sterile, so actually they are grown from single-flowered plants. Heterozygous single-flowered usually produce at least 25% double-flowered variety. However, cultivating Matthiola incana cultivars over the years has improved the odds.
