Plant them together. You can separate if you wish when they get between 12 and 18 inches tall or let them grow together for a "stand". If you separate wait until the mother gets a good start and then take a little bit of her root with each pup. They will wilt when you first take them so leave them in the shade and water well.

Thank You, harleygal... Now my problem is: since I put them in the ground it has rained the last two days a lot.. I hope that doesn't kill this plant :(
