Came across Liatris Spicata with light purple/pink flowers. Labeled to grow to 24-48 in. in height. Looks impressive. Worth planting in Zone 7A (Coastal NY)? Generally how late into fall can it bloom?

Aesthetically our only concern was whether it will be long green stalks with only a bit of purple at the top.

Read it doesn't like overly wet soil, especially in winter, which can lead to rot.

I grow gay feather here and when I lived on Long Island. It is a fabulous plant. It blooms here from mid June until ? It is still blooming.
I deadheaded the first bloom spikes which attracted bees and butterflies. These bloom spikes were 15" tall. They were replaced by three or more per plant. They were about 9" long. I deadheaded those and they are being replaced by more.
I found that they like evenly moist soil, not too dry or not too swamp like.

Thank you, yes it looked pretty impressive. Did you deadhead them when the first blooms were still vibrant, to encourage more blooms, or only after the blooms were spent?

The plants we saw at the Home Depot nursery are about18-20 in. tall now and have bloom spikes that are about 6-8 in. long, of which only the top 2-3 in. have opened into flowers.

If we plant them now, would you cut those bloom spikes? Or should we let them open for the full length of the spike before we cut them?

I like them well enough that I brought them with me from California. I never dead head anything (lazy gardening) so mine are spreading and reseeding themselves. There is a white version too.

Which blooms longer, Liatris Spicata (purple) or Purple Echinacea Pow Wow hybrid? The Echinacea seems to start blooming by early summer and can go to mid-late October here.

There's a spot where we're alternating Black Eyed Susans Goldstrums (24-36 in. tall) with a Purple flower. Currently we have Purple Echinacea Pow Wow in there, but it's half the height of the Black Eyed Susan Goldstrums, so thinking of moving them to another spot and replacing them with the Liatris. What do you think?

I'll try to post a photo of the spot so you can see.

Also we have some Beckie Shasta Daisies we just planted there and we probably won't get a big bloom from them until next summer, once their roots are more established.

Coneflowers bloom until frost, the liatris only lasts a short time.

Daisyl, according to BigBill they go from mid-June through ?, which might not be until frost, but sounds like longer than a short time. Which variety are you growing?

I think the tag said summer through fall, but you can't trust a grower's tag alone. I'll try to look up more about it.

Anyone seen them go from summer into fall?

TreeSong, I put the question mark there because I have buds opening right now for the third blooming on my Liatris. AND they could bloom again!
I have been adding three perennials a year roughly since I moved here in 2018. This year it was Liatris, Shasta Daisies and another type of Salvia.
I lost the first bloom spikes on Liatris in late May, early June due to deer I believe. At that time they nibble phlox to the ground and then they rotted a bit. But right next to the Liatris, the phlox are finally flowering.

I've never paid much attention. I just looked - some inflorescences are about half done blooming and some have not quite started so they will be blooming for quite some time yet. I was agreeing with Pepper, the coneflowers will be blooming until frost as will the beebalms but I don't think the Liatrus bloom that long. And, my Liatrus are only two ft tall. I don't know about cultivars - I have had these in my garden for 40 years.

That's interesting, because while we find Bee Balm a beautifully structured flower, and bees and butterflies love it, we shied away from planting it because we were told it was a shorter bloomer and didn't bloom into fall. Is that true?

We try very hard to get best-bang-for-the-planting-space by planting mostly long-blooming perennials for pollinators - flowers that bloom at least two seasons, such as Black-Eyed Susans Goldstrum and Little Goldster, Purple and Rose Echinacea (Cone Flowers), Catmint (Walker's Low and smaller Cat's Pajamas), Coreopsis (Tickseed), Blue and Red Aster, three varieties of Shasta Daisies, East Friesland Salvia, Purple Pincushion, Lavendar (Provencal and Munstead as one starts blooming a month before the other, so you get a longer bloom) and Blanket flowers. We typically have 3-4 butterflies at a time and many native bees at the flower buffet.

We throw in a few annuals - Wave Petunias and Alyssum to cover a spring bulb bed once the flowers are gone and the leaves are still up collecting energy, and some sunflowers. And later in mid-late fall we'll add Giant Pansies and perhaps Cabbage Flowers.

Other planting space is devoted to a Japanese Maple and evergreen shrubs, an ivy-covered wood fence and soon a few evergreen trees for interest, green in winter and natural habitat for birds and insects.

Asters are wonderful late fall bloomers. They come in a variety of sizes and there are pale purple, pink and reddish flowers. If you pinch then in late April or early May they will start blooming around August and possibly last until mid November.

Tall sedums and mums bloom later in the season providing blooms for the pollinators.

Moms have to be pinched back or they will bloom too early.

By moms, do you mean "mums" as in chrysanthemums? From when to when do they bloom in Zone 7A (coastal NY), and are they perennial in this zone?

When would you "pinch back" mums? Do you mean remove the first flowers or flower buds, or cut back the stems a bit?

We have Lavendar and Red (raspberry color) Aster, knew they bloom into fall, but never knew they bloom late into fall. Great to know.

We'll look into Anise Hyssop - when does it start blooming?

What are examples of tall Sedums? There seem to be so many Sedums, not sure which ones would be considered tall ones.

Are Hardy Geraniums a type of geranium? When do they start blooming and how late do they usually go?

I think the most famous Sedum is "Autumn Joy"

Hardy Geraniums are Geranium sp., the common name (I suspect more than one species) is Cranesbill. I have at least a half dozen, all different colors, sizes, growth habits and leaf types. They start blooming early summer and continue until frost kills them. The same with Anise Hyssop - the size is prett consistent but lots and lots of colors.

My chrysanthemums either bloom mid-summer and are done by fall or start blooming in the fall. I'm not sure what the difference is as I bought them all in the fall as decorations and then planted them out.

If you ask all these questions again in about October, I could go out and see what's still blooming. Whistling

Sorry, I meant mums! And hardy geraniums aren't the ones you see for sale in every garden center every year.
While mums and asters all bloom at different times, they will bloom early unless they're pinched back. That perfect ball of the garden mums you see for sale in October and November? That look is achieved only by scrupulous pinching and pruning from spring on. Too much work for most gardeners, I think. Asters are much easier.
