Distributed over the Olifants River catchment area in the Bronkhorstspruit, Witbank and Middelburg districts of Gauteng. The habitat has typically hot summers and icy winters were this cycad grows in full sun. The leaves are blue-grey to blue-green 60-80cm long. the stems are up to 1.5m long but old reclining specimens can reach up to 3m in length.
“Olifants River Cycad
Encephalartos lanatus, also known as the Olifants River Cycad or the Woolly Cycad, occurs in the upper catchment area of the Olifants River in the Middelburg, Witbank and Bronkhorstspruit districts of the Gauteng and Mpumalanga provinces in South Africa. It also occurs along the Little Olifants and Wilge rivers in this area. It is normally a medium-sized, single-stemmed plant about 1â€“1,5 m high. In the garden, it enjoys a position in full sun and is a strong architectural plant that makes a good focal point. E. lanatus is frost-hardy, fire-adapted and drought-resistant.
It is a small, slow-growing tree with stems usually about 1,5 -2,5m long and 25â€“30 cm in diameter. The young leaves are grey and woolly and have a curved apex. Mature leaves are greyish green, about 60â€“80 cm in length.
Both male and female cones are densely woolly when young, and become yellow with age. They are dioecious, i.e. the cones are borne on separate plants. Female cones are barrel-shaped, 25â€“30 cm long and 12â€“15 mm in diameter. Male cones are cylindrical, 25â€“30 cm long and 5â€“6 cm in diameter. E. lanatus sometimes sends out suckers at the base of the main stem. The mature seeds are yellow and fleshy and smaller than those of other commonly cultivated species such as E. altensteinii.

E. lanatus is easily grown from seed. Hand pollination is necessary for a successful seed harvest in cultivation. Pollen can be collected as soon as it starts shedding. If a slight tapping of the male cone sheds pollen, then the cone is ready to be harvested. Pollen should be stored at â€“ 15°C for best results. The female cone scales have to be monitored to check if they are open. The window of the scale opening varies with plants, from three days to two weeks. The wet method using distilled water in a syringe could give a good pollination rate. After female cones have been collected the seed is left to mature for a year before sowing at the beginning of summer.
For best results, seed is sown in river sand on a heated bench at 24â€“28°C. Germination should start after three weeks after sowing. However, some seeds will take longer.
E. lanatus is slow-growing and reported to be very difficult to transplant; plants die easily or take a long time to recover when transplanted. Leaves and cones are prone to scale and mealybugs.”
