Five autumn perennials for October

Gaura 'Passionate Pink'

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.

Discover five of our favourite autumn perennials for October, below.

The blazing blooms of red-hot pokers (Kniphofia) should last right through autumn.


1

Persicarias

Persicarias are perfect for moist, boggy areas of the garden, as they dislike growing in dry soils. Some of the best flowering persicarias to grow include Persicaria affinis ‘Darjeeling Red’ and Persicaria amplexicaulis ‘Atrosanguinea’.

Michaelmas daisies

Michaelmas daisies, also known as autumn asters, include species like Eurybia macrophylla and Symphyotrichum novi-belgii. Full sun is ideal, and they’ll provide a welcome source of pollen and nectar for late-flying insects.

Kniphofias

Deadheading in summer could result in a second flush of blazing blooms in autumn. Plant red-hot pokers (Kniphofia) in full sun or dappled shade, in a rich soil. Some of our favourite cultivars to grow include ‘Ice Queen’ and ‘Nancy’s Red’.

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.
