'Purple Majesty' is a cultivar of Pennisetum glaucum, or Pearl Millet. Pearl Millet is grown extensively as a grain for both humans and animals, in places like Africa. I've heard of people feeding PM seed to ducks and garden birds, but I've never heard of it being eaten by humans.

I planted a pkt. as a hedge, looks good. Right now it has spikes about 9" long. When do I cut it to save the seeds? I thought about wrapping it with a piece of row cover, tying it to the stem to catch the seeds. The seeds I used were $3 for a pkt of 10 seeds, I'd like to save my own:) Doug.

If your place is like mine, you need to protect the seeds from the birds. I already have Goldfinches and House Finches visiting mine, and the seed isn't ripe yet.

The seed won't be ripe here for quite a while. Long after the plant has started to fail. When they just fall off of their own accord, they're ripe. If you have birds, simply tie pieces of cheesecloth or muslin around each seed head with a twist tie. As long as it's airy and white, the seeds will ripen and the birds won't be able to get them.
