A beautiful Tiarella to add to any collection. I grow mine alongside Geum 'Leonard's Variety' They bloom at the same time in my garden in the UK.
I think this would also look lovely surrounded by Muscari 'Valerie Finnis' which also blooms at the same time here.
I grow it in semi-shade and it multiplies well.

The appearance of this plant changes through the season. If deadheaded, flowering repeats well, lasting well into summer. Little seed is set, but as it is a hybrid, it will not come true from seed.

Like all tiarellas, it needs a deep humusy soil to thrive, but once it is established, it is a carefree woodland plant.

In warmer zones it is evergreen, but in cold winter areas it may die to the ground. Flowering is not affected.
