Dwarf Sweet Peas

As the name would suggest these are sweet peas that grow to a much smaller height. They still produce the same wonderful flowers but just with more compact foliage.

There are lots of different varieties of dwarf sweet pea available and they all have different traits, some will be more dwarf than others but one thing they all share in common is their compact nature.
