This bellflower blooms prolifically over a remarkably long season, opening flowers from spring well into late summer. The tall, slender stems stand steady in the garden without requiring support, and the plant's heirloom pedigree speaks to generations of gardeners who saved and replanted it for its dependable performance. Its resistance to deer browsing and magnetism for pollinators make it as practical as it is beautiful.
Telham Beauty Bellflower is grown as an ornamental perennial, valued for its vertical accent in mixed borders and cottage garden plantings. The tall stems and abundant flowers make it useful for fresh cut arrangements, where the blooms open progressively along the stem to extend the vase life.

Sow seeds indoors in late winter to spring, keeping the seedlings at 65 to 70 degrees Fahrenheit. Surface sow the seeds and press them lightly into the soil; they need light to germinate. Expect sprouts to emerge in 14 to 21 days. Grow seedlings under bright light indoors until they are large enough to transplant.
Transplant seedlings outdoors in spring after the last frost, moving them into a nursery bed in partial shade initially if they were started indoors. Space transplants 6 to 8 inches apart during this stage. In their final garden positions, space plants 12 inches apart. These are typically grown as biennials or short-lived perennials, flowering the second season after sowing.
Direct sow from spring to midsummer in a nursery bed in partial shade, then transplant the seedlings to their permanent positions in the garden the following spring.
