Campanula Species, Clustered Bellflower, Dane's Blood

Beautiful flower but the plant is taking over. The roots even travelled under the sod to come up in ANOTHER flowerbed about 10 feet away...Read More from their point of origin. Need to get it out of the rock garden...to perhaps use it as a border for the yard.

I absolutely ADORE this flower. Fantastic colour! From further away the clustered flowers look a little bit like alliums - huge, rich pur...Read Moreple globes. I really hope what everyone's been saying here is true and it WILL spread. I can't get enough of this plant!!

I inherited a large patch of clustered bellflower when I moved into my house. The flowers are a deep, rich purple and look beautiful whe...Read Moren in bloom. The rest of the time, the plants look weedy, particularly after the flowers fade. In this climate I would describe it as mildly invasive, but manageable.

Very aggressive here. Very bright color not very good lookin foliage though .Depends on what you want personally whether it is a blessing...Read More or a curse.

very striking plant, blooms profusely for 2-3 week in early summer. Can be invasive so plant where it can be controlled

Blooms late June to early July in my garden.

I don't have a large gardening area, so I keep my clustered bellfower in check, not letting it spread. I get total enjoyment from it's be...Read Moreautiful flowers. I did transplant this past early spring and it didn't seem to hurt my plant at all. It is located on the south side of my house and gets plenty of sun in the morning and early afternoon with shade the rest of the day. I can't say enough about how much I enjoy this plant.

In our climate, this plant is EXTREMELY aggressive. I have not found any way to contain it. It is bright purple and does make a fine cu...Read Moret flower, but it just over-runs the columbine and the lawn. Our climate is semi-arid and I think it thrives because it 'grabs' all the water.

This flower flourishes for me. It was very easy to grow, had flowers the first year on shorter plants. The third year it began to grow MU...Read MoreCH taller and spread rapidly (that was good for us then), now I just remove what I do not want and give to others.

The weather here in Vancouver, WA is rainy in the spring & fall, hot and dry in the summer with mild rainy winters. I have this plant on all sides of the house-in sun or shade -does great in not the best soil also.

Had some trouble trasplanting a starter from my Mom. The problem wasn't the plant though. The problem was that I kept pulling it up as ...Read Morea weed! I kept getting new starts because it was a lovely flower, but since it looks kind of ratty and tall before it blooms, I didn't recognise it. It took three years before I finally let the plant go to see what wanted to live so badly, and found out it was my transplants! They looked nice amid my white Iris, and I'm getting great comments on them (see pic).

I was hopeful that this might do well in our garden, as rockery campanulas are rampant here. Sadly this large plant was decimated by slug...Read Mores/snails within a week of planting, so I wouldn't recommend it for anyone with good slug/snail populations. Shame. :(

I grow this in full sun and average soil. It never blooms very much for me and doesn't really increase in size either.
I think the...Read More one I have might be 'Superba', but, I'm not sure.
If anyone has tips on this plant, please, let me know!!! :)
Thanks :)

I look forward to my Superba cultivar blooming every year. I have mine planted in moist, well drained section of my garden and have had ...Read Moreno problem with in becoming invasive - in fact, I added more this year.

My neighbors asked me to identify a plant that mysteriously appeared in their front garden. The calendula is beautiful! It must have been...Read More planted by a bird with good gardening taste. The nice part is that due to shade and several walnut trees in the backyard they have had little success growing flowers in their yard. If the plant is invasive that be be a good thing for Andy and Cheryl.

The jury is still out with my Clustrered Bellflower.

This is only the second year I have had this plant and already have many, many seedlings to share. If I can keep it under control, I will change my rating to a positive....If not, I will be looking for suggestions to keep it contained. It is lovely this year. Has good drainage and full sun.

I have both the cultivar 'Superba' and the var. alba. The adage "1st yr sleep, 2nd yr creep, 3rd yr leap" genuinely applies to this plant...Read More. But in the 3rd yr it looks fantastic, and in subsequent yrs it is even more magnificent. I've got it in rich, organic soil in part sun & I water weekly if the rain doesn't take care of it. The alba is shorter, but 'Superba' gets fairly tall, up to 30". I don't have to stake. Very long bloom time. Cut the flower stalks down to the ground once all blooms finished, but leave basal mound.

I've heard reports of the massive spreading tendencies of the straight species, but have not had the same experience with 'Superba' -- the alba is too new for me to accurately judge yet.
