They are well rooted, trimmed once or twice, and most will bloom this summer! They should be 3 to 4 feet high and attract butterflies (and hummingbirds) like a magnet.

Butterfly bushes are hardy in zones 5 - 9. If you live in a colder zone, the tops in your butterfly bushes will likely die back over the winter. Even so, they will come back the next growing season bigger and better then before. Butterfly bushes prefer full sun (they must receive eight or more hours of sun a day to thrive).
