The first time I grew this bellflower, native to Greece, I managed to raise just a single plant from seed, but it was worth the effort. In its second season, it first set a large number of interestingly shaped buds, that proceeded to open just about all at the same time, to reveal powder-blue flowers shaped like flared cups, all held upward to allow a peek inside the bells. According to online sources, it is monocarpic – which means it won't return the year after it flowers. That was true for our plant, and since I did not manage to collect seed, it expired from our garden for years. More recently, I traded for new seed, getting a better crop of plants. Those took three years before they decided to bloom, and the flowers turned out to be white. I will be sure to collect seed this time.

|This is the only campanula I've grown that is evergreen in our climate. Still sporting last year's leaves in this early-April photo. |
We left this plant behind in our Pennsylvania garden (and wish it well); we don't grow it in Houston.
Seed for this plant is included on my seed trade list

You're probably in zone 9 - warm enough not to worry about survival through winter - but if it's monocarpic, it will still need to be re-established from seed every year. Ours didn't return after the year it bloomed.
|Evelyn Gooch||Jul 19, 2009||The label doesn't say monocarpic on it. It does say "Heavenly Bells". Will that make a difference?|
Monocarpic means that the plant lives to flower - after it blooms and sets seed, the plant dies. I don't know if C. incurva is monocarpic, but some internet sources suggest it is, and that matches my own experience.
|Kristin||Jan 06, 2013||Wow , what a beautiful plant . Your picture of it is wonderful. I would sure love to get some seeds for that Beauty. It has a very interesting shape and I love the color. You must have a fabulous garden, so many beautiful plants and a great variety.|
|Elizabeth||Mar 19, 2017||I bought a single plant two years ago. I am really hoping that it will bloom this year. No buds yet. I'm in San Marcos, CA, zone 10a.|
|Patty Rissberger ||Apr 08, 2017|| I believe that this native Campanula from Greece comes in a darker blue or purple form? Or am I looking at a different species that I received in a flower a big bouquet. They are stunning and I'm willing to grow them even if they die after blooming. Can you give me information on where to get seeds and/or whether I am off with the species. I'm happy to send a photo of what I have because they're still going strong in her flower bouquet indoors. I live in the willamette Valley in Oregon. I will also try to research through the Zupans from which I believe the flowers were purchased Here in Oregon. Thank you|
Many campanulas show color variations within a species. I'm certainly no expert, and don't know what range of colors for C. incurva takes on. I certainly agree they are quite nice when blooming en masse!
- Seed from '10 trade. Baggy 70F with light (87%G, 6-9d)
Baggy 35F (93%G, 5-7w)
- Same seed as above, cold-stored through summer. Baggy 70F with light (78%G, 7-12d)
- Same seed as above, cold-stored. Baggy 70F with light (75%G, 7-18d)
- Same seed as above, cold-stored. Baggy 70F with light (90%G, 6-14d)
- Same seed as above, cold-stored. Baggy 70F with light (90%G, 6-11d)
Apparently properly stored seed maintains high viability for years.
