I was hoping they were perennial (I always have to look up the spelling!
), but they're an annual.
But still blooming after at least a month.
I've been saving the seeds, though not sure how viable they are.
Will try to get them to establish.
BTW, I got them at Home Depot.
Just bought seeds at Amazon for a purple & white mix Outsidepride Globe Amaranth 1000 Seeds, and Outsidepride Yellow Craspedia Globosa Billy Button or Drumstick 1000 Seeds. Should make a nice combo.
