Pretty blue or purple flowers are always a treat in the garden. I added a taller bellflower to my garden earlier this spring, Campanula ‘Summertime Blues’. It has the typical purplish blue flowers of Campanula, and is supposed to bloom for a long time. It is covered in many beautiful bells. This bellflower is planted in a more sunny/part shade area of the garden.
Campanula ‘Summertime Blues’ is supposed to be very well behaved, not seeding or sending out runners. I haven’t had any problems with my bellflowers spreading to the point of annoyance, other than C. glomerata (which is my least favourite bellflower) self seeding, but if they do overly well in your area, this might be a good one for your garden.
The plants are about 70 cm (2.5 ft) tall. The foliage is a little coarse on this perennial, but the colouring is nice. The leaves are a dark, rich green, while the contrasting stems are reddish. When the multitude of flowers open on ‘Summertime Blues’, the foliage is the last thing you notice.
These flowers of Campanula ‘Summertime Blues’ have the classic downward facing bells. The ends of the bells flare out slightly. The flowers are larger than most bellflowers, about 5 cm (2 in) long. They look almost blue individually, but in front of the bright blue lobelia you can see that Summertime Blues are actually a lavender blue, with a slight silver tone. The buds are a reddish purple colour. There are an amazing number of flowers, from the top to the bottom of this large bellflower, so it doesn’t really need other plants in front of it. I have an annual short blue lobelia in front of them.
I have this Campanula planted in front of some Phlox paniculata (tall garden phlox). Since ‘Summertime Blues’ is supposed to flower all season, they should look nice later in the summer with the flowering phlox. There are some Dianthus (pink carnations) to one side, and a pink ‘Sarah Bernhardt’ peony behind them. The river of sky blue lobelia flows in and around the area.
Because I only added the perennials to the garden a month and a half ago, it is hard to tell what the typical flower number will be. However, there were no blooms on these bellflowers when I bought them, and now they are laden with flowers. The plants droop a bit with such a heavy load of pretty petals, but manage to hold them all off of the ground. I might have this Campanula give some lessons to the peony.
Campanula ‘Summertime Blues’ adds many beautiful purplish blue flowers to the garden. I’ll know more about its actual bloom length by this fall, and its hardiness by next spring.
