8 Fall-Flowering Perennials to Discover

Standard

There are plenty of fall-flowering perennials. Photo: http://www.scenicrootsgardencenter.com

Can it really be the end of August already? Where did the summer go? But you needn’t cry over its demise, at least, not if you’re a gardener, as you can easily extend summer into October—or even November in milder climates—with a selection of perennials that bloom at the end of the season. All you have to do is to add them here and there and voilà! Your flower beds will perk right up with extraordinary blooms and, since they’re perennials, the bloom will repeat each fall. 

Here are 8 favorite fall bloomers:

Fall perennial white flowers Anemone × hybrida ‘Honorine Jobert’

1. Fall Anemone (Anemone tomentosa ‘Robustissima’, A. hupehensisA. × hybrida and others): Generally a spreading perennial that forms large colonies over time, although some modern varieties are clump-forming and not as invasive. Beautiful maple-leaf shaped foliage forming a carpet. Large camellia-like single or semi-double flowers in pink, white, purple or red with a yellow center. Prefers partial shade, but tolerates sun in more humid locations. 12–40 inches × 12–24 inches (30–100 cm × 30–60 cm). Hardiness zone: 4 or 5 to 8, depending on the variety.

Fall perennial aster Symphyotrichum novae-angliae ‘Purple Dome’

2. Fall Aster (Symphyotrichum novae-angliae [Aster novae-angliae], S. novi-belgii [A. novi-belgii] and others): There is a plethora of fall asters in a wide range of hues—purple, pink, red, white and more—and heights, ranging from rounded domes for the foreground to tall backdrop plants. The small star-shaped flowers (Aster means star) are borne in dense masses. Some start blooming in late summer and continue into fall, others are strictly fall bloomers. For sun or partial shade in rather rich, well-drained soil that is not too dry. 10–80 inches × 12–36 inches (25–200 cm × 30–90 cm). Hardiness zone: 3 or 4 to 8.

3. Fall Mum or Cushion Mum (Chrysanthemum × morifolium and others): Masses of daisy or pompom-shaped flowers beginning at the very end of summer into fall for some, starting in fall for others, some continuing right to the start of winter. Wide choice of colors. Look specifically for varieties that are hardy enough for your local climate: no-name varieties sold at bargain prices are usually tender varieties unable to support cold winters. Sun or partial shade in rich, well-drained soil. 18–30 inches × 20–50 inches (45–75 cm × 50–120 cm). Hardiness zone: 3, 4 or 5 to 8 for hardy mums, 7 to 9 for tender mums.

Fall perennial Purple coneflower Echinacea × hybrida Sombrero Baja Burgundy

4. Echinacea (Echinacea purpurea and others): The famous “purple coneflower” now comes in a much wider choice of colors—white, orange, yellow, red, pink and green—as well as shapes—single, double, semi-double, and so on—and blooms from August to September, sometimes October. The flower looks like a daisy with a raised yellow, orange, red or green heart. Let the flower dry in place for a nice winter effect and this will also feed seed-eating birds. For sun or light shade in well-drained soil. 18–50 inches × 24 inches (45–120 cm × 60 cm). Hardiness zone: 3 to 8.

Fall perennial Joe-Pye Weed Eupatorium maculatum ‘Atropupureum’

5. Joe-Pye Weed (Eupatorium maculatum, now Eutrochium maculatum): Tall background perennial with beautifully whorled leaves, covered with domes of feathery pinkish-purple flowers that butterflies love. Flowers in August and September. Prefers sun or partial shade and rather humid soil. 60–80 inches × 60–80 inches (1.5-2 m × 1.5-2 m). Hardiness zone: 2 to 9.

6. Ornamental grasses (CalamagrostisMiscanthusMolinaPanicumPennisetum, etc.): There are lots of fall-flowering grasses and most continue to beautify the garden even after they have died, as they stand tall for months, carrying the season of interest right through to spring. Narrow leaves, feathery flowers. Most are adapted to full sun and well-drained soils. Variable height and diameter. Hardiness zone: highly variable, from 3, 4 or 5 to 8 for some, 6 or 7 to 9 or 10 for others.

Fall perennial Rudbeckia fulgida sullivantii ‘Goldsturm’

7. Orange Coneflower (Rudbeckia fulgida): This popular perennial bears yellow daisy-shaped inflorescences with a dark brown domed center. In most climates, it will already have been in bloom since July, but will continue to flower through September. Easy to grow in sun or very light shade and any well-drained soil. 24–28 inches × 18 inches (60–70 cm × 45 cm). Hardiness zone: 3 to 9. There are several other fall-flowering perennial coneflowers: R. laciniataR. triloba, etc.

Fall perennial Hylotelephium spectabile ‘Neon’

8. Showy Stonecrop (Hylotelephium spectabile [Sedum spectabile] and others): This rather short plant is ideal for the front of the garden. It forms a dome of succulent leaves on thick stems. The massed domed flowers can be pink, red or white and attract butterflies. The leaves can be bluish green, variegated or purple. Full sun and well-drained soil. Highly drought tolerant. Plenty of choice! 12–24 inches × 12–24 inches (30–60 cm × 30–60 cm). Hardiness zone: 3 to 9.

    I rather like Sky Blue Aster, Symphyotrichum oolentangiense, commonly called azure aster or blue devils, which features clouds of very small, pale blue/lavender flowers. it does self-seed pretty freely so if you don’t want to deal with seedlings, cut the stalks back when they turn into puffballs of seeds.

    One question, one comment, and a note from the South:

    Question – is there something else in the picture of the echinacea? Monarda, maybe? Does it bloom in the fall, too?

    Comment – I’ve always found Rudbeckia to be very invasive.

    Note from the South – it is still 85 – 90 degrees and humid. But the plants know that fall is coming. The tomatoes and green peppers are gone. Some of the annuals are on their way out, too.

    • 1. Nope, they’re all just echinaceas, but the ones on the left are semi-double.

      2. Many are, given the right conditions. But they’re pretty!

      3. It’s the shortening days. Even so, I suspect many of your plants hang on longer than in my cold northern garden where it’s really getting very cool at night (about 45 F tonight).

  3. No matter how I think I have Autumn covered with flowering plants (and I have almost everyone you have mentioned here) .. I want more .. the rudbeckia can be invasive but all you have to do is pull them out .. it isn’t a huge deal.
    Even though I am exhausted from summer .. and I am glad Autumn is coming .. that fear of such a long winter gnaws at me, maybe that is the cause of wanting more flowering plants this time of year .. pack the plants in to enjoy them before the snow flys !

  4. Fall anemones are so elegant! I want to grow them, but they do not do well here. (They appreciate a bit of humidity.) There is a small colony at work that will neither perform well, nor die. It just sort of survives. I will eventually take pieces of it to put in other locations to hopefully find a spot where they a re happy, perhaps down in a riparian situation. The color is a rather bland pale pink, but if they do well, I can add a richer pink or preferably white! Actually, I would be pleased with the bland pale pink, just because it is an anemone.
    I also want to grow Joe Pye weed, because it is something that is unknown here, but that so many in other regions enjoy. Sedum is new to me, but blooms earlier, which is fine.
