Aureum growing in a variety of situations. Most notably, several plants of cv. Aureum with entirely green leaf laminae were observed that retained the distinctive overall appearance of the variegated plants. Furtado's comment that the variegated plant 'reverts' to the typical green plant in shady situations was not supported by my observations in Bogor where mature variegated plants were often seen in deep shade and adult green plants could be seen in full sun. This suggests that the green forms are somatic segregates from the variegated chimera.
Most literature emphasises the shy-flowering nature of cv.
Enquiries at Bogor confirmed that both the variegated and the wholly green plants of cv. Aureum cultivated there are shy-flowering. This is in marked contrast to E. pinnatum which flowers profusely wherever it occurs in the wild and in cultivation.
