I planted a hardy hibiscus a number of years ago worrying that it would be a needy plant that I'd have to coddle to see any blooms.
Well, it's not. It's just slower showing up than most of the plants in my garden. It produces pretty pink blooms.
I planted it near our neighbor's fence so it would get some protection from the south wind. One of my sister-in-laws suggested I put in a small support frame to keep it from falling over when it blooms.
