tuberosum is found in the Pyrenees in rocky
habitats, the plant gets its name from its tuberous
roots. I found it some years ago when on a AGS trip
to eastern Spain; however the flowers were very
small in comparison to the plants back in my garden.
Thalictrum tuberosum may be grown in a raised bed or
large trough, it seems to prefer a humus - rich,
well drained soil.
Rarely offered by nurseries, it is forever present
in AGS and SRGC seed exchange seed lists .
