Dahlia (Dahlia spp.), The grow from 1 to 8 meters high can grow from a tuberous root. Other members of the family are tuber anemone (Anemone Blanda), which grows in size from 6 to 48 inches depending on the variety and caladium (Caladium x hortulanum), which grows 12 to 24 cm high.
Rhizomes grow below or right at the bottom. Iris (Iris germanica) that grows 1 to 3 meters high, is one example of a rhizome.
