Thundercloud Thalictrum aquilegifolium
Airy Purple Blooms on Graceful Red Stems
The impressive blooms come on early in the season, opening in June. The show lasts for about a month, during which the sweet, airy scent of the blooms attracts bees and butterflies. Luckily, deer don't find 'Thundercloud' as appetizing. Naturally, this Meadow Rue is an excellent choice for any meadow- or woodland-themed garden. But the graceful blooms are also amazing for cutting or drying.
The big panicles and wiry stems create an ethereal effect, but the heavy blooms also mean that Meadow Rue can have a tendency to "flop". Grow 'Thundercloud' next to a fence or something it can lean on, or use stakes when growing it in the open.
This hardy native grows 24 to 36 inches tall and 18 to 24 inches wide and requires very little. It prefers partial shade and moist, rich soil, but it survives in a huge range of conditions, including sun, drought, poor soil (even clay), and cold. Though most sources only recommend it for zones 5 to 8, there are reports of this cold-hardy plant thriving in New York, Minnesota, Wisconsin, and even as far north as zone 2a!
