21Rouge, mine all get less than 2 hours of sun and still bloom. Some of them get maybe a half hour of sun, and they still bloom. Mine flower for about 6 weeks in mid summer.

Very striking flower. How much shade can it ‘tolerate’ ie and still bloom? And what is its bloom period?

Susan, this bellflower would look great softening the edges of your paving, a river of bluish purple winding through your patio.. Mine fills the gap between a sidewalk and cement foundation with those prolific flowers.

This grows between the cracks in my paving in UK – I love it. Survives frost and snow too.

Sheri, C. portenschlagiana ‘Hoffman’s Blue’ is a really nice looking bellflower, and blooms very well, so it is great for the garden. I’m not sure of other sources for this plant now, but good luck in locating it.

I just saw these in the Portland, OR area, in someone yard ( They were having a yard sale ) I took a photo of them with my iphone, did some research…and lo and behold! I seem to be able to find on your site… But can’t seem to find them any where else. Would you be able to help me locate these, even in seed form, I would be forever grateful : )

Thank you, Sheri

Johanna, the C. portenschlagiana does spread well after a year or two. However, they don’t bloom all summer, like many annuals would, so you would probably want some other flowers with them to extend the blooming time. When they are in flower, these bellflowers put on a great show, and they are easy to look after.

I bought a pot of Portenschlagiana and I wonder, if I put them in a large rectangular container whether they would spread to fill it all and be so the main character on my balcony?

# 11, I haven’t had a problem with these spreading into unwanted areas.

I’m pretty sure I have this growing throughout my yard in PA. What will kill it and not kill the grass?
