Will do best if planted in deeply cultivated soil with compost added. Likes loamy soil.
Will re-bloom if deadheaded.
No serious pests or diseases.
They don't like wet feet.
Cover the crown with straw or other mulch for winter protection.

Seed Germination: Sow indoors at 55-72° with no cover as light aids in germination. Sow seeds 10-12 weeks before planting out. Expect germination in 15-25 days. It is not recommended to sow seeds outdoors as seeds are very small.

I've found this species to be hardy but short-lived here in zone 3 Calgary, Alberta.
