Iberis amara (common name: rocket candytuft)

Propagation: Seed - sow spring in situ for summer flowering or late summer in situ for a spring flowering[1]. The seed germinates within 3 weeks.

Cultivation: Easily grown in a good, well-drained ordinary garden soil in a sunny position[2]. Prefers a calcareous soil but tolerates mildly acid soils[2]. Succeeds in poor soils[1] and on dry walls[2].

A very ornamental plant[2]. A fast growing plant[3], do not grow the plants too close together[2].

The flowers are sweetly scented[4].

Range: Western and southern Europe, including Britain, to N. Africa.

Habitat: Dry calcareous soils on hillsides and in cornfields[5].

Edibility: The seeds are sometimes used as a source of mustard[6][7][8]. Pungency of mustard develops when cold water is added to the ground-up seed - an enzyme (myrosin) acts on a glycoside (sinigrin) to produce a sulphur compound. The reaction takes 10 - 15 minutes. Mixing with hot water or vinegar, or adding salt, inhibits the enzyme and produces a mild bitter mustard[9].

Medicinal: Little used in modern herbalism, rocket candytuft is a bitter-tasting tonic, aiding digestion and relieving wind and bloating[10]. It is traditionally taken to treat gout, rheumatism and arthritis[10].

All parts of the plant are antirheumatic and antiscorbutic[6]. The seeds are considered very useful in the treatment of asthma, bronchitis and dropsy[11][12]. The plant is gathered in the summer and can be dried for later use[10]. The seeds are harvested when fully ripe[10].

A common homeopathic remedy is made from the seeds[11].

Pollinators: Bees

Soil: Can grow in light, medium, and heavy soils.

Drainage: Prefers well drained soil.

Flower Type: Hermaphrodite
