In the ornamental plant industry, most plants are grown in containers using organic substrate such as peat, bark, and coir dust combinations as growing media, in which soil is almost completely excluded. Naturally, silicon (Si) in those media is quite limited. The addition of calcium silicate to the growth media would provide an available silicon source to the potted plants.

The following table lists plants responsive to silicon accumulation and growth. A more comprehensive study of silicon uptake, by varities, of horticultural plants was investigated by the University of Florida. Click on orange orchids image for more information.
