Thalictrum rochebrunianum (Giant Meadow Rue) [15 Seeds]

(1 customer review)


Germination Information: I recommend these seeds only for gardeners who have experience with perennial seeds that have multi-cycle germination patterns. I find it easiest to sow (barely covered with growing medium) in October through January and set the pot outdoors, so the seeds can germinate when conditions are right in spring. (Seeds I sowed on January 14, 2023, using the winter-sowing method began germinating on March 25, 2023.) I have also read that they can be sown indoors in cool or warm conditions, but germination may be slow and erratic, and the seeds may end up needing an artificial chilling period (in a refrigerator) of 4 to 8 weeks if there is no apparent sprouting after a few weeks. I must admit that I have not had luck with indoor sowing when I have tried it.

Once you get giant meadow rue to flower in your garden, there’s a pretty good chance that it will self-sow (though not to the point of being problematic).

Note that this information will not appear on the seed packet you receive.

Both of the common names of Thalictrum rochebrunianum—giant meadow rue and lavender mist—give you a good idea what to expect from this elegant perennial. In average soil, it’s usually 4 to 6 feet tall; in rich, moist soil, it can easily reach 6 to 8 feet in height. The upright stems carry lacy leaves and are topped with airy clouds of small, pinkish purple flowers, mostly in late summer. Giant meadow rue shows off best in large groups, and/or against a dark background, such as a deep green hedge or tree or a dark-colored wall. Light shade is ideal in most areas. Perennial; Zones 4 to 7 or 8.

2022-collected seeds are sold out. I hope to collect again in September 2023. At least 15 seeds.
