Plants of the Thalictrum genus are hardy perennials that range in height from 30 cm to 2 metres (1 to 7 feet).
They have an attractive foliage. This may be toothed or lobed. Plants bloom in the summer, carrying fluffy flowers of purple, pink, white or yellow.
Some common names for Thalictrum include Feathered Columbine, and Meadow Rue.

It is best to grow feathered Thalictrum from fresh seeds in the autumn, or from divided plants in the spring.
The seeds should be sown at a depth of 3 mm (1/8th inch) into flats, and the flat sank into a shady part of the garden. The flat should then be covered with glass and the soil kept moist.
Germination of Thalictrum species is a little hit and miss. It may take from two weeks to two years.
Once seedlings are growing strongly, transplant them in the autumn into a partially shaded location of the garden (they will grow fine in sunny areas in cool areas). Use a spacing of between 15 cm / 6 inches (small varieties) to 90 cm / 3 feet (larger plants).
Ideally the soil that they grow in should be acidic (pH 5 to 6) and moist.
It is fairly easy to look after members of Thalictrum such as feathered columbine and Meadow Rue. They should be mulched and lightly fertilized in the spring. The soil should be kept moist, so water during dry periods.
Large Thalictrum plants should be staked. Cut back the plants to ground level in the autumn.
If you require more plants, then they can be propagated through division at the start of spring.
