Looking for a splash of colour
I have a fairly large balcony (30 square metres, 300 square feet). I have quite a lot going on out there, and I'm quite pleased with how it looks. I've tried to aim for a cottage garden kind of feel, with lots of smaller pots, a few climbers, plenty of foliage and herbs. Because of space constraints, I try for long flowering season. I always prefer perennials where feasible, and don't mind spending quite a bit of time wrapping things up in winter. I've had a good run with that, even keeping my olive tree going for quite a few years now.
I've noticed however that I'm leaning towards blues, mauves and pinks with all the lavender, violas, catmint, pinks, wallflower, sweet alyssum, campanulas and lobelias.
So what I'd like to add would be something really bold to offset all that. I'm thinking something orange or yellow, with a long flowering season. Any suggestions would be gratefully received!
