Last year I grew Rosella Crimson. It was in a 5 gallon pot. Its height was about 3 ft. But Dwarf Purple Heart grew up to 5ft. I am growing DPH this year too. It was the most productive of all my dwarfs.

Nope. My Rosella Purple was the same height as most of the others when I grew them last year (4 to 5').

A short one is Arctic Rose (a pink).

Linda, mine was NOT RP. It was CRIMSON. But normally plants stay smaller in small containers, But then Dwarf Purple Heart was also in the same size container. So , not all dwarfs are the same size.
