Tall amethyst spikes bloom all summer long. Excellent cut flower with nodding bell-shaped blossoms are mildly fragrant. Gather for fresh flower bouquets. Makes a nice vertical accent for the middle of a perennial border.
Adenophora are profuse bloomers with many spikes of colorful bells in summer. Give them room to spread to make a spectacular show en masse.

Adenophora 'Amethyst'
Deadheading will prevent seeding and a barrier will help with running if spread is not wanted. A better choice than Campanula for southern gardens.
To promote bushiness, Adenophora may be cut back by one-half in May when they reach 6-8" tall. Cut plants down to basal foliage in fall, clean up in spring. Long-lived. Roots deeply, so may be difficult to divide.
Our plants are grown in 3.5x3.5x4” plantable pots. Made from 100% biodegradable coconut husk fibers (coir), these pots have tremendous advantages over plastic pots. With better air exchange, this "breathable" pot fosters robust root growth and reduces transplant shock since you can plant the pots directly in the ground. The pot naturally becomes part of the soil on its own over time—no composting required—and since they're made from a renewable resource that requires very little energy, they're earth-friendly too!
