I found this variegated ligularia in a small independent nursery in our area called Ito Nursery. There was no name on it but it fits in fine in the Moonlight Garden in the shady areas where the soil stays cool and damp between waterings.
It is growing larger and this spring it appears that the new growth is coming out almost pure white! I'm assuming this is because of a lack of light, although you can see by the photos it does get some dappled sunlight. Whatever the cause, it is interesting and works for me!
