9. Sun spots?

Adromischus plants often have spotted markings upon their leaves. In winter, these fade in colour, but fortunately the colour returns each summer with better sunshine and higher temperatures - as with our human suntans! Bryan Makin used to achieve wonderful colouring by growing plants in a low glass frame and removing the top during the summer months to provide direct sunshine. Thus, as much sunshine as possible is generally recommended for these plants to bring out their best colours. If grown in shade, such as under greenhouse staging, Adro's rapidly become non-descript, leggy and green.

However, beware of scorching at the hottest times for section 2 & 3 species. These usually grow in shaded rock cracks. I remember finding A. schuldtianus in Namibia all along a deep fissure under a reef of rock, where the sun would never reach, but water could trickle.

Occasionally as a plant grows, the spots increase in area. Some sports can be completely covered with the red colouring and these are, of course, highly valued horticulturally. Two examples that I have grown are: A. alstonii (as A. triflorus) ISI 1377 and an A. marianiae purple sport from Chris Rodgerson.
