There are a number of perennials that flower in October, and they’ll combine beautifully with the autumn foliage of trees and shrubs.
To prolong their display, deadhead regularly. Autumn is a great time to collect seeds from perennials too, before storing them for spring sowings.

Save money, buy bare-root
If you’ve got a lot of space to fill, it’s well worth buying perennials bare-root, as they’ll be cheaper than potted plants. Bare-root perennials are usually available in the dormant months from November to March, and can easily be potted up once bought, ready for planting out in spring.
