We had tons of rain for a week in the spring and I thought it was dead. It came right back and is bigger than ever! |

Negative | On Apr 12, 2010, braun06 from Irving, TX (Zone 8a) wrote: I was not impressed with this plant. All the marketing photos show a variety of colors on each flower head but the plant I had only caried the same color with golden center to each floret. I dont know if this is typical. |
Negative | On May 15, 2008, victorgardener from Lower Hudson Valley, NY (Zone 6b) wrote: Gorgeous flowers and of course is a butterfly magnet. But it's proven to be terribly invasive here if you don't cut every spent bloom. I have methodically pulled out every one I could find. |
Positive | On Oct 16, 2006, Meredith79 from Southeastern, NH (Zone 5b) wrote: I think this is the only butterfy bush worth having. It is very fragrant and the fragrance is much nicer than the smell of all the other butterfly bushes I have and that I've seen in nurseries. Oh, and of course all butterflies love it! Just beware, butterfly bushes have been put on many states invasive plant lists. I keep mine dead-headed just in case, it needs it to bloom it's best anyways. |

It remains relatively small in contrast to some the others that I have. It does attract butterflies and hummingbirds into my yard. I would suggest this plant to anyone in the northern zones looking for a smaller butterfly bush to add to their garden. ( I live in zone 5b). |
