A Week of Flowers 2025 – If It’s Thursday, It’s August

At the beginning of August, before the summer drought sunk its ragged, unclipped talons deep into the soil, flowers on the taller-than-me stalks of Silphium perfoliatum started to open. The cup plant gets its common name from the way pairs of leaves join at the base, enveloping the stalk to create a cup. The daisy-like flowers attract many flying pollinators and the seeds seem to be tasty for certain small birds. It spreads easily by seed and a few stalks will quickly become a very large clump if happily situated.

I’m joining Cathy all week as she hosts seven days of colour to remind us of the beauty from the past spring and summer – all with the goal of making a cold and perhaps grey and snowy December a bit more bearable.

  1. A lovely yellow daisy type flower. I wondered why they are called cup plants. I do have one in my garden, but failed to notice the leaves. I must pay more attention next year. Thanks for sharing! πŸ˜ƒπŸŒΌβ˜€οΈ

  2. I think I remembered about the height from one of your previous postings. This isn’t one of our native species, but it’s interesting how similar its buds are to our Silphium radula, the rough-stemmed rosinweed. I like the slender rays of this one, as well as the sunny color.
