Phyteuma scheuchzeri  is an unusual, easy to grow rock garden plant, with a bizarre flower. It is a close relative of the bellflower but does not look anything like it. I think the flowers look more like an Allium. The flower head consists of a number of flowers all opening at the same time. Each flower is quite spiky in appearance, creating a big spiky ball of rich blue color.

The rampion  is native to the mountains of Europe and is also commonly called Oxford rampion and horned rampion.

It grows easily from seed and forms a nice compact clump. I have it growing in both full sun and part shade and it seems to like both conditions. It will be shorter if given more light and less water.

The plant is rated to zone 5, but it has overwintered in a raised trough during 2013 and 2014 – two very cold winters for zone 5. I’d expect it to survive zone 4.

I have been gardening my whole life and have a science background. Besides writing and speaking about gardening, I own and operate a 6 acre private garden called Aspen Grove Gardens which now has over 3,000 perennials, grasses, shrubs and trees. Yes--I am a plantaholic!

  1. It grows beautifully in Zone 9B too. We’re in Sonoma County. So, given Sylvia in zone 3’s comment, perhaps the USDA Hardiness Zone might be updatable from “(4?) 5 – 8” to zones 3-9B.

  2. Just stumbled across this site. Have saved it for a better “look/see” once the winter rains and grey arrive. Really nicely laid-out. Thank you. Have shared it with other gardeners here on Salt Spring Isl. Will check out the FB page as well.
