Collection of 3 Thalictrums rose lilac

Despite its delicate and fragile appearance, the Thalictrum is very hardy and low-maintenance. It simply needs to be planted in partial shade or even full shade, in a moist to wet soil that is rich in organic matter and well-drained, without too much limestone. It can also be established in full sun, as long as the soil remains moist and the plant is surrounded by ambient humidity.

Planting can be done in spring or autumn. Planting it at the base of a north or east-facing wall is ideal. Don't hesitate to amend the soil with compost every year to improve drainage in winter and facilitate root development. Also, remember to water regularly during dry and hot periods. Regularly deadhead the flowers to prolong flowering. It loses its leaves in autumn and completely disappears in winter, only reappearing quite late in spring. Therefore, it is advisable not to cut the plant to the ground in autumn, so as not to forget its location the following spring. It is a bit slow to establish, but it will delight gardeners over the years! Due to its size, staking may be necessary, especially if this Meadow-rue is used as a standalone plant or in a windy location. To avoid this inconvenience, it is recommended to plant it in the middle of other plants and bushes that it can lean on. Dividing the clumps can be done in March-April by cutting the plant into several pieces with a spade, but the divisions take a long time to establish. While it is highly resistant to diseases, it may be susceptible to powdery mildew during drought and slug attacks at the start of the growing season.
