Modern Design is doing well in my garden. It has a great spot and rewards me with abundant flowers. Unfortunately it does not rebloom and therefore it is only during a short period of time. Drought resistance is average and it forms brown tips on foliage if it is stressed due to a shortage of water. I'm in zone 5 and it has been through some very cold winters (up to -26 degrees F) and it never has caused an issue.
