HARDY PERENNIALS: TIARELLA

T. cordifolia is the aptly named ‘Foam Flower’. It needs a shady place and leafy or peaty lime free soil. In this it will spread quickly with pretty leaves of a somewhat golden hue, and in May-June is covered with 6 inches sprays of foamy white flowers. Division is best in autumn or very early spring. T. wherryi h taller and has very little surface spread. Instead it makes a low mound of golden green, prettily zoned leaves of ivy shape and carries a long suc-cesion of 12 inches spikes of creamy-white. This is one of the parents of Heucherella ‘Bridget Bloom’ but is a very worthy plant in its own right for a cool shady place. T. po/y-phylla is more adaptable, making leafy evergreen hummocks bearing 10 inches sprays of flowers like tiny pearls, from June to August.
