Tiarella x ‘Elizabeth Oliver’ – Foamflower – 1.25-Quart

$7.00

From the breeders, Charles & Martha Oliver: “Tiarella ‘Elizabeth Oliver’ has become a classic among the fancy-leaved varieties of foamflower available today. It was the earliest of the hybrids between eastern and western Tiarella to become widely known, and it is an ancestor of almost all of the cut-leaved forms currently on the world market. Like its namesake, it is still among the very best available.

‘Elizabeth Oliver’ looks best planted in drifts several feet wide next to paths in a woodland garden or along the front of a shady border. Tall, slender plants can easily come up through mats of Tiarella, so ‘Elizabeth Oliver’ can be allowed to spread back into flower beds around the stems of species like Cimicifuga, Actaea, or Kirengeshoma or around large ferns.

Description

Saxifrage family, Saxifragaceae

There are two varieties of foamflower in the Eastern United States – var. cordifolia, which occurs in the Catskills and is a running form, producing above ground stolons and slowly forming a groundcover, and var. collina, which occurs from Maryland to Kentucky south to Mississippi and Georgia and is a clumping form. T. cordifolia var. collina is often also listed as T. wherryi in horticulture though that is simply a botanical synonym not a different species.

We generally assign clumping horticultural forms to T. cordifolia var. collina and running horticultural forms to T. cordifolia var. cordifolia, though not all horticultural varieties are straight species and may be hybrids between the two – a western species, T. trifoliata, may also be involved in the parentage of many cultivars.
