Autumn blooms come in three categories: fall-only bloomers, “summer” annuals, and rebloomers. Because of this, September usually has more blooming plants than August.
Cyclamen purpurascens only blooms in the fall. It is considered one of the cold-hardiest cyclamens for the garden.
Japanese anemones also only bloom in autumn. This one is ‘Honorine Jobert’.
Fire Light® Hydrangea (H. paniculata ‘SMHPFL’), which Proven Winners sent to me to trial, blooms in August but doesn’t color up until September.
‘Lemon Queen’ helianthus opens a few flowers in late August, but doesn’t hit her stride until September.
‘Lemon Queen’ is big, and needs big companions, like these Miscanthus ‘Morning Light’ in the Slope Garden.
Harumph. My hardy hibiscus are supposed to be summer bloomers, but they are just opening their first buds this week. This one is ‘Cherry Cheesecake’, a sample plant from Proven Winners.I thought it was plenty hot this summer, but perhaps our cooler-than-typical spring slowed them down.
I am used to heat-loving annuals, such as this Rose Bon Bon cosmos from Renee’s Garden, taking their sweet time to bloom. If I start them indoors, they don’t bloom until late July. And if I sow them in the ground where they are to grow, as I did with this particular plant, they don’t bloom until August, and are at their peak in September, shortly before frost cuts them down.
The cool evening temperatures stimulate a second flush of bloom on roses, such as Flower Carpet® Amber…
…Darcey Bussell, a David Austin rose,…
…Flower Carpet® Pink Supreme…
…and ‘Sophy’s Rose’, also from David Austin.
When you combine fall-bloomers, late-bloomers, and rebloomers in one bed, it hardly looks like the fall garden is waning.
Left to right: ‘Disraeli/Beaconsfield’ colchicums, Knautia macedonica ‘Thunder and Lightning’, Buddleia ‘Glass Slippers’, Salvia transsylvanica, pink Phlox paniculata (second flush), ‘Sophy’s Rose’, Lychnis coronaria ‘Alba’, Cosmos ‘Rose Bon Bon’, Salvia forskaohlei (Click photo to enlarge)
Can’t find the knautia in the photo above? It’s at the bottom near the left corner of the bed, a little bit to the right of the tent stake. It’s not blooming heavily now, nor did it bloom heavily all summer, but the foliage makes it a keeper.
With thoughtful planning and cooperative weather, September can be a floriferous month. What’s growing now in your garden?
Inspired by the words of Elizabeth Lawrence, “We can have flowers nearly every month of the year,” Carol of May Dreams Gardens started Garden Bloggers Bloom Day. On the 15th of every month, garden bloggers from all over the world publish what is currently blooming in their gardens, and leave a link in the comments of May Dreams Gardens.
