Purple, I will warn about any plant I know to be invasive in my area (zone 8, Pacific Northwest, especially the Puget Sound area). A good number of plant species that are invasive in other parts of the country have not (yet) proven to be so here. And vice versa. Some - like Buddleia - have been found to be very problematic here but not so much elsewhere. Invasiveness is very regionally oriented :-) And while I have defended Vinca minor (not V. major) as not being a particularly invasive species in my area, I do caution against planting it close to any natural or wooded area because it can and will spread. But it is not to the point of it being considered a noxious weed or a listed invasive species. OTOH, I defy anyone to find where I have ever, ever defended Hedera helix on any of these forums. I won't even recommend this plant in areas where it is not considered to be particularly invasive (typically only those areas cold enough to kill it back in winter!!) because it provides an excellent habitat for all manner of vermin. And in the PNW, this plant is perhaps the most pervasive invasive plant problem we deal with. And it is everywhere. Buddleia davidii is an especially prolific and fertile seeder. Each flower head can contain as much as 40,000 seeds and with an 80% germination viability. That's a whole lotta potential butterfly bushes!! And you do see them growing wild in my area - in the cracks of abandoned parking lots, in vacant lots, along railroad tracks and the sides of the road and freeway verges. And most disturbing are the large colonies of these shrubs found along streamsides and cleared areas throughout western Washington and Oregon. They outcompete native habitat, in particular our native shrub willows, which are the preferred habitat for our native butterfly species. I'm not saying BB is invasive everywhere - again, with any invasive species it is location, location, location! However I know specifically where Cadence is located, which just north of my own location, and plants which are invasive here will also tend to be invasive there. As part of a consumer awareness program sponsored by our state invasive species council, the regional professional landscape and nursery association and a consortium of local retail nurseries, a publication recommending alternate suggestions for invasive plants has been made available. Substitutes for BB include west coast natives Ceanothus and Pacific ninebark as well as chaste tree. And of course, the new sterile BB cultivars recently introduced to the consumer market.

I don't mind at all Sherry. I'm happy to see other people starting threads with the same theme or any threads for that matter. I'm so glad to have something to read and the beautiful photos to look at when I sit down at the computer. It's my "me time" when I need a break. You've all posted such wonderful photos! My Pink Delight butterfly bush is getting crowded out by other shrubs in my mixed border and it hasn't bloomed very well the last couple years so I don't have many photos of butterflies on it. I rooted a start and moved it to another area last spring so maybe next summer will be better. I looked through my photos and found one of a Viceroy And I think this is a Great Spangled Frit

If so, how do you like it? TIA
