Rare little offering from Siberia with very thin creeping rhizomes making a small ferny colony in light shade. One of the last to bloom of the tuberous species, this usually shows its mauve-pink small tubular flowers in May. Loves a woodsy soil which would make a Primrose happy. Very hardy. Don't be dismayed by the lack of roots that should be filling the pot as this is just not what they do. If dormant, you can separate the thin yellowish rhizomes and spread them out slightly pointing them in different directions for a bit speedier cover.
