Cannas Anyone?

I thinned out my yellow cannas this week, separated and potted them up.  If you live nearby and want some for free, come and get 'em.  They are supposed to be a dwarf variety, so said the label, and only get about four feet high, but they actually grow to at least six feet high.

They are beautiful, but beware, they spread like crazy.

In June of 2010, I planted this sparse row.

By August, they looked like this.  In the summer of 2011, they doubled and pretty much took over the whole bed so that the dwarf ruellia (the pink row of flowers) could hardly be seen.
