The plants can be grown in the garden or a container and can flower from November to April depending on the variety.
HTA consultant David Gilchrist said: "Camellias grow well with other ericaceous plants such as Rhododendron, Pieris, and Enkianthu, deciduous and evergreen azaleas. They prefer acid soil, so use ericaceous compost if growing in a container."
The HTA’s Plant of the Month campaign highlights the plants that are widely available and looking especially good in garden centres and nurseries each month. They are nominated and agreed upon by British growers and retailers.
