Care of the plant Centaurea cineraria or Velvet centaurea |
|
The genus Centaurea, family Asteraceae, includes 700 species of herbaceous perennial or annual plants native to Africa, the Mediterranean region, Australia and America (South and North). Some species are: Centaurea cineraria, Centaurea cachinalensis, Centaurea cyanus, Centaurea moschata, Centaurea candidissima, Centaurea babylonica, Centaurea macrocephala. Common names: Velvet centaurea, Dusty miller, Silver dust. This species is native to the Island of Capraia in Italy. They are perennial plants (annuals in regions of cold winters) that reach 70 cm (2.29 feet) in height. They are very interesting for the silvery gray arched lobed foliage that contrast with green leafy plants. They produce yellow or white flowers that are not decorative; the flowers are usually removed to favor the appearance of new leaves. They bloom in summer. These fast-growing plants are used to form clumps and borders and in pots for decks and patios. They are ideal for gardens by the sea due to their resistance to salinity and wind. Centaurea cineraria is an easy-to-grow plant that prefers full sun exposure. They resist light frosts. The soil must be well drained; they can grow in poor, dry soils. Transplant in early spring. Water with little water (never puddle) once a week in summer. Wait for the soil to dry well before watering; they resist drought well. Fertilize with compost or manure in the fall. They do not need pruning but it's advisable to remove flower buds. Prune intensively every 3 years to strengthen the plant. They are resistant to pests but can be attacked by fungi if there is excess humidity. They propagate by seeds sown in early spring. |
