What’s in bloom in September?

posted in: Gardening | 11

What’s in bloom in September? The garden has mostly had to look after itself for the past month and has coped pretty well despite having been a very absentee gardener. Despite my absence here are my reliable late summer bloomers which are flowering today for Garden Bloggers Bloom Day.  Furthermore, they are all listed with their Scottish hardiness ratings.

In Bloom in September


Monbretia:  Lucifer takes to the stage in August while September is the best month for this passalong Crocosmia. The clump grows alongside a Cercis canadensis ‘Forest Pansy’ so hence the reason for the lovely dark coloured leaves in the background of the photograph.

Lysimachia ciliata ‘Firecracker’

Loosestripe:  It just shows how desperate I was when I bought this plant though after 3 years it still has never become invasive as the border is so wet. It grows alongside the Primula japonica  ‘Millers Crimson.

Echinops ritro

Globe Thistle: This plant with its thistle like leaves is just starting to become established in the garden. In fact it’s a great nectar source for the wildlife in the garden.

Lythrum salicaria

Purple loosestrife:  A few clumps of Lythrum grow in the same border as the Lysimachia.  It’s really tall at between 5-6 feet and grows really well without being invasive and without being staked.

Lilium ‘Stargazer’

I grow this in the warmest part of the garden where the soil gets sunshine 12 months of the year to protect the bulbs from winter wet and cold.  It grows in a sheltered position that traps its fragrance.

Sedum spectabile ‘Autumn Joy’

Ice plant: I have many clumps around the garden as they are such a great nectar source for the wildlife.

Verbena and Rudbeckia

Rudbeckia is the star of the borders just now. Moreover, I’m sure it will still be looking good in October too. It grows alongside purple verbenas and Geranium ‘Rozanne’ which makes for a lovely contrast in colour. The verbena will never survive a Scottish winter!

There are plenty more plants in flower including many from What’s in bloom in August 2012 post …

  • Astilbe chinensis H5 with its pink fluffy spires.
  • Aster ‘Bahamas’ Island Series H5 with mildew resistant button-shaped blooms in shades of rose red.
  • Clematis ‘Gypsy Queen’ H4/5  large flowers scrambling through the foliage.
  • Spirea ‘Shirobana’ H5 has a mixture of white and pink flowers all on the same shrub.

Caryopteris clandonensis ‘Heavenly Blue’

It has beautiful aromatic silvery-green foliage and striking tiny bright blue flowers. However, this plant needs a sheltered position.

Finally, this is my favourite in the border for late summer colour and it’s also the hardiest verbena to grow in Scotland

    Gorgeous flowers! I do love Crocosmia, and I've been looking for something yellow to pair with Geranium 'Rozanne' so I'll investigate the Rudbeckia. Your macro lense separates foreground and background beautifully.

    Your late summer blooms are stunning, Rosie! Crocosmia blooms much earlier here, but I was delighted to see mine rebloom last week. Purple loosestrife is banned in this area as it is invasive and destroying our wetlands. Love your delicate-looking verbina.

    Rosie, September is proving to be better than the Summer months up here in Aberdeen. You have fabulous September plants. Our Montbretia isn't doing so well this year, I really think it is needing thinned out.

    Hello Rosie, I have not been coming here more often because most of your previous posts are not in my line of expertise, the computer softwares! But when it is flower posts and GBBD i am again coming in. There is always the characteristic English garden in your photos, always marvelous! Best regards

    The Crocosmia in our garden has had a very good season and a fair clump of it is positioned right next to our runner beans. The Bees and Hoverflies fly back and forth from the Crocosmia to the runner beans and do a great job in pollinating them.

    These are excellent photographs of your lovely garden flowers.

    The wild variety of your Verbena is called Blue Vervain here in Michigan.

    Our wild Purple Loosestrife is considered an invasive plant in our wetlands.

    Thanks again for sharing your garden with us.
