(2 years old seedling) The rare silver form of Cycas siamensis is a very striking plant, both glinting and elegantly characterized by its emergent leaves that are more silvery-grey than the standard species. The leaves retain much of this colouring over time. However the young seedlings are dark green in colour for some years.
