i live in the n. east. i have been trying to start some butterfly weed for two years now. last year it was spindly, maybe 9 inches tall--swallow tail caterpillars ate it in oct. i figured it would be fine and come back, i was wrong. so this year i replanted and it did fine, then around late oct. it dropped its leaves. i am wondering if this happens and it will come back, or if it is lost too. no caterpillars this time, but i was not expecting to see it lose it's leaves. i have heard that they can be hard to start, any info would be great!
oh, i replanted in two places-both plots lost leaves.
