How to Grow Arabis species such as Rock Cress and Wall Cress
It is best to sow out Arabis species on the soil surface, following germination they can be thinned out with a spacing of approximately thirteen to thirty centimeters.
Rock cress should be sown out in the early spring when a light frost is still possible or in the late autumn; they require the vernalisation process to flower. The plants prefer to be grown in full sunlight, but are quite hardy and therefore tolerant to light shady conditions.
The soil type is not overly important, but it should be well drained, and ideally (though not essentially) have a pH of 5.5 to 7. When starting Arabis off from seed indoors, the seeds should be given six to eight weeks before planning to plant out in peat pots. They should be pricked out in the Early Spring.
Caring for Arabis
Arabis are very easy to look after and the plant should be deadheaded following flowering to prevent self fertilization and to maintain a neat appearance.
A member of the Arabis family; the annual Arabidopsis thaliana, is one of the most used plants in biological research; it is a model species, with five chromosomes and has been fully sequenced. Research onto the plant has led to a great increase in the understanding of how plants function.
