Trachelium caeruleum
Hamer Pandora

Dark, fluffy, and wonderfully dramatic, Trachelium caeruleum ‘Hamer Pandora’ is a deeper-toned blue lace flower with big, rounded clusters of dark purple blooms up to 5" across. Each flower head is made up of tiny blossoms with pale pin-like details, creating a lacy landing pad that butterflies adore and gardeners cannot help admiring.

Also known as Blue Lace Flower, ‘Hamer Pandora’ grows on fast, easy, branching stems about 2–3' tall, with gorgeous dark purple-black foliage that adds even more depth to the display. It is fabulous in cutting gardens, pollinator beds, cottage borders, containers, and summer-to-fall arrangements where its moody color and airy texture can really shine.

Plant Trachelium caeruleum ‘Hamer Pandora’ in full sun to part shade with rich, well-drained soil. Deadhead regularly to encourage bloom from summer into fall, and cut freely for bouquets. Elegant, nectar-rich, and deliciously unusual, it brings serious flower power to annual plantings. Explore more seasonal treasures in our Annuals collection.
