Cosmos bipinnatus

Pale purple coneflower? {{gwi:1068289}}

Phlox paniculata? Not sure if that meets the growing criteria. Here's a nice Texas page.

Pink wildflowers that will do well on roadsides in north Texas include Wild Bergamot - Monarda fistulosa, and coneflowers. There is the Pale Purple Coneflower - Echinacea pallida?, and Purple Coneflower - Echinacea purpurea, which really is more pink than purple.

The cosmos shown above isn't native to the US, so I wouldn't call it a wildflower. It is an easy to grow annual that might be a good choice for the first year or so before the perennials fill in. Don't plant the cosmos too thick or they will shade the others and the others will be slower to fill in.

Oh ladyslppr, thanks for that correction. Apparently it is native to Mexico? I could've sworn that I verified that.

Cosmos parviflorus is a native one (also appears to be pink).

I am not sure which of these of are appropriate for your zone, but these are pink natives that I am familiar with...

joepyeweeed, eupatorium maculatum
queen of the prairie, filipendula rubra
meadow rose, rosa blanda
red milkweed, asclepias incanarta
the blazingstars range from pink to purple, the liatris family
downy phlox, plox pilosa
prairie smoke, geum triflorum
fire pink, silene virginica

Some fleabanes are pink. Or they start out pink and fade to white. I had a great crop a few years ago and they were charming. Fleabanes are leggy plants that sometimes fall over late in the season. The blossoms are tiny. They re-seed decently.

This link gives a clear way to distinguish common fleabane from daisy fleabane.

new england asters can be pink.

The Rose Pink, Sabatia angularis, is my favorite pink one.

Does anyone here know where I might buy seed? It occurs some years and not others on a rocky couth facing road cut on our property. I thought I'd see if I could bring into the garden.

There are pink versions of you native winecups (Calirohoe involucrata)which grow along the roadsides in your area. I have them in my garden up here in PA. White, pink, and the deep wine color all come out as seedlings.

i've seen a wild phlox here in indiana that's a very attractive pink...also, there's a wild thistle that's illegal to cultivate here that's just wonderful in bloom, and i'd grow it if i didn't fear the human authority figures....stupid government :(

Here's a Texas native that will attract TONS of butterflies.
