Campanula rapunculus 'Heavenly Blue'
Trial: Annual
Year Trialed: 2004
Year of Trial: First (from 2004 report)
Good Qualities:
Great color (5); Good filler (3); Long stems; Many small flowers for bouquet use: Gives a bouquet a great airy graceful look, long lasting in vase, no other annual looks like it; More lavender than blue, just keeps flowering, strong wiry stems; Easy to grow; We liked it.
Problems:
Will never grow outside in N.H., will grow in tunnel only; Somewhat tedious to harvest to get the long stems, the flower stems just keep coming so we harvest the whole plant and in a couple of weeks more flowers, even the short stems are useful in small bouquets; Dead blooms stay on and are hard to remove for a 'clean' look, Is this a cultivar that becomes invasive?
Postharvest:
Cut when first flowers show.

Comments:
We grow other campanulas, but none with the fine and delicate colors of this one; In the tunnel - 2nd heavy flowering on very short stems; We will certainly grow this one next year.
