I have a hanging basket that I'd like to put something in that flowers but doesn't die off at the end of summer. I don't know if there are any shallow rooted perennials but I thought I'd ask. It's about 8-10in deep and like 12-14in wide. Whatever I plant obviously doesn't need to flower all year but I'd like it stay green when it's not blooming, so not bulbs. I have geraniums in a larger hanging pot so I know those work but I don't think this pot is big enough for a geranium. If there isn't anything can anyone recommend an annual that lasts into late summer at least? We don't really get nights under 50 degrees until December around here.
