This is a small, compact but intriguing Geum. I'm not quite sure if it's orange, yellow or purple - it seems to cover quite a range of shades within an average day. Like with all geums the flowers rise above the foliage and then gracefully turn downwards, similar to an aquilegia. I grow Geums on the side of my pond, they create a beautiful effect, it's almost as if the flowers are floating.
Not a huge amount of care needed. I lost a geum due to getting waterlogged so be aware of this. Dead heading flowers will prologue the flowering period.
