I realize this is not the answer you might have hoped for but...
if it's Pampas grass and has viable seeds I would not plant them - period!

Pampas grass is lovely but I learned the hard way that the sharp edges of the plant made it impossible for me to do any work near the plants - arms and legs get sliced badly. It took me 3 years to find someone willing to remove the plants from my yard.

Sorry I could not give you a more positive answer. Hope you have more luck with yours. Crossing Fingers!

Lots of fake photoshopped purple pampas images online, I do hope you saw actual photos because they won't look anything like this.

Here is a how-to for sowing but they also contains a warning:
"Pampas grass makes many invasive plant species lists because it produces and self-sows large numbers of seeds with a high germination success rate. Left unchecked, plants can crowd out native species. Methods to control your pampas grass include pulling up seedlings manually, removing the flower plumes before the plant goes to seed, and removing developing seeds before they drop."

From what I understand pampas grass is potentially not hardy enough for zone 6b. You'd probably be better planting one of the nicer Miscanthus.

Yup, forgot to add that.
Winter hardy to USDA Zones 8-10, it's native to Brazil, Argentina and Chile.

Missouri Botanical Garden website says "In the St. Louis area (USDA Zone 6), this grass will generally not survive winter, and should be planted in large containers (e.g., whiskey barrels) for overwintering in a greenhouse."

Pampas is actually hardy to zone 5 in some places. I'm in zone 5 here and they're found all over the area. Smiling

If you plant the seeds just be aware of it's potential to be invasive and hard to remove as mentioned above. Thumbs up

I only found one shorter variety that says it's more cold hardy down to zone 5.

There are some that are hardier, but the purple one is usually listed as Zone 7 and warmer. Erianthus ravennae is also sold as "hardy pampas grass" but isn't a Cortaderia like the true ones.

Read all the answers and did not get a bit of help on the question. How do you grow pampas from seed? I know all about the plants as my neighbor has them and I want to get seed but need instructions on how to plant and grow the seed. Sad Sad Sad

When I asked your question of the folks at Texas A&M I received this answer.

It is interesting to grow Pampas grass from seed. What you need to know is that the seeds need light to germinate, so with your pre dampened planting mixture (peat moss and sand) spread the seeds on top of the soil and gently press down on the seeds.
I would use a spray bottle to keep the soil damp but not wet. Seeds should germinate 21-25 days .

An item of interest is that the pampas grass grown from seed may not be the same as what you get from the nursery because the nursery sells female pampas grass that have larger plumes than male pampas grass. From seed you will get both male and female plants.

I hope this helps & thanks for the question .
