Yellow Perennials That Bloom in Late Summer
Today I want to tell you about three late-flowering yellow perennials that make great bedfellows. Use these three together and your late-summer border is going to be the talk of the town!
1. Dwarf Goldenrod (Solidago 'Little Lemon')
My first plant is the shortest of the three, and being just 1.5 feet tall, makes an ideal plant for mid or front of the border. This is a dwarf goldenrod or solidago called 'Little Lemon'.
Solidago 'Little Lemon' produces dense, cheery plumes of golden flowers from late summer into autumn. The plumes are scented and also make great cut flowers for the house.
Perhaps you've been wary of growing goldenrod in the past because of its reputation for spreading. If so, this compact clumping plant is the one for you!
Tips for Growing 'Little Lemon' Goldenrod
Grow 'Little Lemon' in poor or moderately fertile, well-drained soil in full sun. It's suitable for US hardiness zones 5 to 9.
2. Sneezeweed (Helenium 'Riverton Beauty')
Next up is a helenium called 'Riverton Beauty'. It has clear, pale yellow flowers with contrasting maroon bosses held in masses from August right into autumn. This plant is tall, coming in at nearly four feet, so it may need staking, but this is a small price to pay for the breathtaking spectacle it'll give you.
Tips for Growing 'Riverton Beauty' Sneezeweed
Grow this helenium in any good, moist, well-drained soil in full sun for four months of blooming pleasure. Heleniums are suitable for US zones 3 to 8.
3. Coneflower (Rudbeckia 'Herbstsonne')
My final plant is a rudbeckia. Now there are plenty of rudbeckias that look fabulous at this time of year, but this one, this one is a giant! Rudbeckia 'Herbstsonne', or Rudbeckia Autumn Sun, grows to 6.5 feet and is a robust plant bearing single golden flowers with an elongated eye.
It flowers from mid to late summer and looks fabulous at the back of a border.
Tips for Growing 'Herbstsonne' Coneflower
Grow in moderately fertile, moist but well-drained soil in full sun. It can tolerate partial shade, but appreciates a sheltered position. It's tall enough that it'll probably need staking! Rudbeckia 'Herbstsonne' is suitable for zones 3 to 9.
So for late summer gold, why not try Solidago 'Little Lemon', Helenium 'Riverton Beauty' or Rudbeckia Herbstsonne?
