When everything else has faded in late fall, asters are just beginning their show.
They come in shades of lavender, blue, pink, and purple. Some will even survive a light frost. They need full sun, and pollinators love them!
Your garden will glow with these sunny yellow blooms, which appear from mid-summer to fall.
The foliage has a low, clumping habit, while the flowers are quite tall. Read the tag: while some are long-lived perennials, others are shorter lived biennials or annuals. Bonus: They reseed, meaning more free plants over time. Give them full sun.

Nothing says fall like mums! They're perennial if you get them in the ground early in the season (spring through mid-summer) so that their roots can get established.
If you plant them too late in fall, they may not have enough time to get settled before winter so they're treated as annuals. Plant some in every color!

Give them plenty of full sun and space to grow because they don't like being moved (they tend not to bloom the next year), and they don't like being crowded! The ants you see are just coming to sip nectar; they don't harm the plant.
