Purple Meadow Rue
(Meadow Rue)
Thalictrum dasycarpum
[C-value
5]
Buttercup family (Ranunculaceae)
Blooms June -
mid-July
The native Purple Meadow Rue is uncommon in our area. It prefers full
sun to light shade and wet to slightly moist conditions. Habitats include
river-bottom prairies, savannas, floodplain woodlands, swamps, and edges
of
fens. This
perennial
is 3-7' tall with a central stem that is unbranched below, becoming branched above. The alternate leaves are
ternately
compound and up to 2' long and across, becoming smaller as
they ascend the stems. Purple Meadow Rue is
dioecious
- individual
plants produce either all male or all female flowers. Regardless of
gender, the central stem terminates in a
panicle
of flowers
about ¾-2' long and about 1' across. Male
flowers are about 1/3" long, consisting of 4-5
deciduous
sepals
and up
to 15
stamens
and no petals. Female
flowers are about 1/3" long, consisting of 4-5 deciduous sepals and up
to 15 light green
pistils.
