What are the pros? PROLIFIC!
What are the cons? HUGE!
These ate my garden this past season. I don't know what a regular size nasturtium does, but these got at least two feet high and sprawled to nearly three feet in diameter PER PLANT. I planted two. Lordy! BUT! I'm not complaining. I love plants that love my garden. The leaves and flowers of this plant are flat out delicious and the flowers smell heavenly! Who knew? If you've got narrow pathways to navigate in a small space like me, these are not a good edge plant, but try them in pots or give them their own corner and they will reward you handsomely!
