Although colder weather may be with us now, or on its way, there’s no reason why we can’t make our gardens look warm and cheerful. So, start by choosing plants that flower at this time of year or display bright colour leaves, with these 10 top plants for October…
1. Hesperantha coccinea (crimson flag lily) ‘Major’

- Flowers in summer and autumn
- Hardy through most of the UK
- Grows to 75cm tall
- Moist but well-drained soil
- Full sun
- Sheltered
2. Cornus sanguinea (dogwood) ‘Winter Beauty’
Next is a hardy shrub that provides great autumn interest when its leaves turn fantastic shades of orange and red as the temperatures start to drop. When the sun shines, the plant reveals cheerful pale yellow and red colour stems to brighten the garden during the dull, cold winter months.
- Interesting foliage all year round
- Fully hardy
- Grows to 2m tall
- Moist but well-drained or well-drained soil
- Full sun or partial shade

3. Leucanthemella serotina (autumn ox-eye)
This cheerful looking perennial is a very late flowering daisy plant producing numerous sprays of very white flowers. The flowers turn their face to the sun, just like sunflowers do! They look wonderful placed at the back of the flower border and happily grow without the need for staking too.

4. Acidanthera murielae (Abyssinian gladiolus)

5. Liriope muscari (big blue lily turf)
It’s sometimes difficult to find good, easy to care for plants that grow well in dry shade. However, lily turf is one such plant that will thrive in those conditions. What’s more, they have handsome, grass-like, evergreen leaves that form neat mounds for low maintenance gardening. Another bonus is the spikes of bright violet flowers that appear at this time of year.

7. Persicaria amplexicaulis (red bistort) ‘Fat Domino’

Their wide, shallow flowerheads attract lots of butterflies and bees and are easy to grow and look after. ‘Red Cauli’ will be covered in bright red coloured, small domed heads of flowers. The stems and leaves are both dark red making this a very striking plant for the front of a flower border.

Amelanchier are small deciduous trees that are ideal for the smaller garden.

Amelanchier love growing in boggy, damp soil, and for the best autumn colour plant them in full sun.
