Here are some photos I just took in my yard of Spanish Bluebells and why I consider them aggressive weeds. Please note that I never planted them, they have spread by seeding and I've been digging them out twenty years....all these beds were lawn when we bought the house but there were some Spanish Bluebells in the neighbor's yard and on the side of the house by a big Hydrangea that seeded....Yes, I know I've got other weeds too ;) They grow up into the crowns of other plants and are very hard to dig out. They just finished blooming so they aren't as easy to see in the photos. They'll turn yellow in a couple of weeks and get very slimy and attract slugs like crazy too.

FWIW, Mine are planted at the base of oak trees. They grow and multiply, but slowly. I'm not sure I would call them "flourishing", but having never planted them elsewhere, or, for that matter, having never even seen them in anyone else's garden, I don't know how to compare mine to others planted in different situations. Just this year I noticed about half a dozen new plants, a bit farther away from the originals, and they too have seeded - and are growing - under other oak trees. I do believe oaks are easier to plant under than other trees, so I don't know if that should be taken into account. Dee

Thanks! The originals came from my grandmother's house, which then became my parents'; and they were actually dormant when I moved them. The property was being sold and that was my only option. I was lucky any made it. So they have a lot of sentimental value. I even have a seedling all the way on the opposite side of the house. How a seed got there is a mystery, unless on my foot. I've never even noticed the seeds, or I'd collect them.

Nate, hello. I'm just on the other side of Tysons Corner off Rt 7. If you want to hop on over this way I can share some pulmonaria. Daylilly99@cox.net
