Growing and Saving the Seeds Of Iceplant

Latin name Mesembryanthemum crystallinum is a frost-tender succulent plant that can grow as an annual or perennial. The beautiful plants appear to be covered in glistening water droplets, hence the name iceplant. This wild and unique plant has a low growing, creeping habit with eye-catching foliage and sweet, understated flowers.



Native to South Africa, and possibly the Egyptian peninsula of Sinai and southern Europe. A halophyte, or salt-loving, plant that accumulates or pulls salt from the soil, it has been used in phytoremediation of contaminated sites.
