How Late In Calandar Year Can Perennials, My Hummingbird Plants That Are 3 Weeks Grown Indoors, Be Planted Outside For The Followi

Question

ng year? Are there specific perennials that definitely should not be planted in the late summer or fall?

Answer 1

This isn't ideal, but the fast growing plant would likely handle it. The only issue that I see is that you are, barely, outside of their growing zone. However, mulching will likely help for the winter. These plants will enjoy a planting as it is starting to get hot for the year.
