Campanula ‘Camgood'
Flowering now at Juniper Level is one of my all-time favorite perennials...Campanula porscharkyana 'Camgood'. This amazing perennial flowers as well in full sun as in light shade. Best of all, it's easy to grow and doesn't run like many bellflowers. I can't imagine gardening without it. Hardiness is Zone 4-7 at least.
