Buy Mukdenia rossii 'Karasuba' (syn. Mukdenia rossii 'Crimson Fans'): Attractive groundcover for shade

This perennial dies back to below ground level each year in autumn, then fresh new growth appears again in spring.

  • Position: partial shade
  • Soil: moist but well drained, humus-rich soil
  • Rate of growth: slow to average
  • Flowering period: March to May
  • Hardiness: fully hardy

    Spreading slowly by underground rhizomes to form a clump of rich green maple-like foliage, this attractive perennial also produces pretty sprays of bell-shaped white flowers in spring. Towards the end of summer, the foliage takes on rich claret tones before it starts to die back and sometimes this can be quite dazzling. Originating from wooded areas in N. E. Asia, it provides valuable groundcover in shadier positions and looks particularly good when planted in drifts.

  • Garden care: Lift and divide overly large clumps in spring, just before new growth begins. Protect the newly emerging foliage from slugs and snails. Keep well watered during the warmer months.

Hasn't grown as expected. Weak growth.


Not grown much. Very small compared with description




Another nice plant from Crocus


A really attractive plant to have in groups at the front of a shady border.

I have Mukdenia "Crimson Fans" under a Euonymus standard. It gets sun for about four hours from 3:30 until 7:00 or so on the north side of my house. Lovely from spring until late August, when it has never gotten the red colouring, instead turning yellow in late August. I transplanted a piece to another location that gets morning sun until around noon. The leaves of this one are turning red. (Toronto area, Ontario, Canada zone 6) My actual question is: When I transplant the rest of the one under the Euonymus, do I cover the rhizomes or leave them on top of the soil, which is where they are under the Euonymus standard?


Hello there I would cover the rhizomes. Hope this helps

Is this non toxic to cats and dogs?


Hello, It might be worth checking with your vet, but I have double checked both the cats protection and dogs trust websites and I cannot see this plant on their list of poisonous plants.


Hi. I have 2 H. Seemanii, each in a large trough. I would like to underplant them with something to prolong their season of interest but am mindful of root space. Would either Mukdenia rosii karasuba or Helleborusniger be suitable? They would be in john innes no 3 compost in a north facing, mostly shaded area. Thank you for your assistance.


Hello, This hydrangea does get pretty big, so it will eventually be feeling cramped in a pot. With this in mind, I would be reluctant to plant anything that gets too large as they will be competing for water and nutrients. In the long term this competition may become too much for anything with a smaller root system, but if the hydrangeas have only recently been planted, then you should be able to introduce either of the plants you mention. If however the hydrangeas are well established, then I would just dress the pots with some decorative gravel.
