Hi Sheri,
I am in zone 8b as well and have had good success with yarrow. About two years ago, I grew two plants from seed. This is the first year they have bloomed. I have them in a partly sunny area, facing North/Northeast. They require a light-mild watering 2x a week or a more thorough watering 1x a week. One is straight, the other has spilled over. I may divide that plant this fall and give it some support for next year. But the blooms are absolutely beautiful and have lasted a long time. I took these pictures about two weeks ago and since then, more blooms have appeared, making the yarrow more full. I encourage you to try yarrow out again. I'm in North Texas and it can get quite hot and humid. Yarrow has proven to be a great plant for me, given I started my plants from seed and they've only known this climate. I regret not planting more. Their beauty is best displayed in mass planting. I've started 12 more plants from seed and hope to have blooms in a year and a half. It's worth the wait for me!
