These are deciduous hybrids, they grow well in the cooler areas of Australia and are frost hardy, however they do not do well in warmer climates for these areas choose evergreen hybrids.

In the course of their breeding, M. Koster and Sons discovered that if certain selected Mollis azaleas are crossed, the progeny is more or less uniform in colour, and it is therefore possible, by repeating the cross annually, to produce quantities of seedling azaleas true to colour. Of the varieties described here, ‘Babeuff’ (the original clone only) comes fairly true from seed when isolated. It had white flowers, flushed with pink at the edge, spotted with yellow on the upper lobe and with a tinge of yellow in the throat.
