For toughness and presence, Strelitzias are hard to beat. Mine is in a harsh spot, up against a glass wall in full north sun and lots of wind, but it does well and flowers from late summer. A bonus is that every year it has a couple more flowers so it’s nice to watch it grow.
I remember as a kid I used to think that they are messy flowers, and didn’t see the attraction (they are very common in Perth, reflecting their resilience to hot dry weather and wind). But now I would have to have one in my garden. It would be nice to mix them up with heliconias, maybe. This one is in a tall (1m) concrete pot which it shares with the red crucifix orchid.
