The trees that once shaded our little squares of garden are long gone, but many plants that once graced the forest floor can thrive in the shade of the buildings that have sprung up in their place. In early spring, these ephemeral wonders bloom before the trees leaf out, photosynthesize like mad, and then often go dormant till the following year.
Its spring arrival is a wonderful drama:
There's a double form available, which is stunningly beautiful, but there's something magic about the water-lily flowers of the straight species, floating above the leaves, which continue to expand toto soak up all the sun they can once the short-lived blooms are spent. The double flowers last longer, but spread more slowly - they're sterile.
