Hi Donna,
I believe the Coneflower plants can be kept in pots. If you want to attract the Monarch butterfly caterpillar, (by having butterflies lay eggs on the plant) SWAMP Milkweed (Asclepias Incarnata) is one of the better varieties for pots. Internet may be best place to look because not too many local nurseries carry it--at least in my area. Just make sure the plant hasn't been sprayed with anything otherwise the chemicals will kill the caterpillars.
