we had canna at the formerly matrimonial home..
i was a sucker for borders filled with hot colours, from memory we also had. red hot pokers, bishop of llandaff dahlias, castor oil plants, sunflowers, red bananas, foxtail lillies, hostas even bird of paradise in pots, which we brought in during winter. i suppose the warning is this that it can become addictive, that kind of floral display. Labour intensive to maintain, not cheap, looked exotic though. on my trips to Colombia is recent years it was all of that and more except everything grew four times quicker constant mild spring like conditions.
