Paris daisy: Argyranthemum frutescens
This bushy semi-shrub is a member of the aster family (Asteraceae) and native to the Canary Islands.
The daisy-likeare in fact inflorescences with yellow tubular centre florets surrounded by white, pink or yellow ray florets, depending on the variety. Outdoors they flower continuously throughout the summer while in a conservatory they flower even longer. In order to ensure this prolific flowering, they require a lot of sun, water and food. During periods of hot weather, they must often be watered twice a day. In the growing period they must be given weekly application of a complete fertilizer.
They need to be placed in a sheltered position where they are protected from the wind. Dead flowers should be removed regularly. Larger specimens are cut back in spring and if there is limited space for over-wintering, this can be done earlier, in the autumn. Depending on the brightness, the plants should over-winter in a well-ventilated room to prevent grey mould at a temperature of 5-15° C (41-59° F). The easiest way to propagate is from tip cuttings in spring. Watch out for greenfly and blackfly.
