We’ve grown lots of campanulas (bell flower) through the years….109 of them, to be precise. Some are good garden plants, many die, and some even try to take over the garden. After 35 years of trials, the star of the genus is still Campanula ‘Sarastro’. Discovered, named, and introduced by Christian Kress of Austria’s Sarastro Nursery, this superb selection never fails to impress. Here’s our photo this week of it in the sunny gardens here at JLBG, where it reaches 2′ in height and 3′ in width.
