Flower: pale-yellow to white
Blooming season: Autumn to spring (mainly in early to late spring).
Cultivation and propagation: Very suitable for bonsai.
Exposure: They require direct sunlight when in full growth, while a filtered exposition is best during the hottest period of summer, when the plants enter in their dormancy phase. They always grow best in positions where they receive long periods of strong sunlight
Watering: They need to be regularly watered every 6 to 10 days whilst they are in active growth and producing leaves, occasionally during dormancy. It is very important that there is plenty of free air circulation around cultivated plants and also that they are not overwatered.
