Almost as important to me as the unusual leaves is the fact that they emerge later in the spring than those of most perennials. I've taken advantage of this habit by underplanting the entire bed with early tulips, Roman hyacinths, and daffodils. The foliage of these spring bulbs is already starting to die off when the slender shoots of Painter's Palette make their appearance. The unsightly foliage is soon completely hidden as this Persicaria grows rapidly to a mature height of about 20 inches.
I use Firetail to hide unsightly growth as well. The subject to be hidden here is 'John Cabot', a climbing rose,. By mid-summer, it's lost its leaves from the ground up to about two feet. The bare, very thorny canes are not only unsightly but downright menacing, especially if I'm weeding in their vicinity. Firetail's exuberant growth and reddish, tail-like blooms cover the bare canes beautifully. Unlike the meandering nature of Painter's Palette, Firetail stays put in an ever-expanding clump. Simply divide it when it gets too big and share some with fellow gardeners or find another spot for it in your own garden.
Judging from my chats with other gardeners, Persicarias are not well known to many here in the U.S. And there are other garden-worthy species. Among them are Persicaria microcephala 'Red Dragon', Persicaria orientalis (aka "Kiss Me Over the Garden Gate), Persicaria capitata ("pink knotweed"), and Persicaria amphibia ("water smartweed"). Why not try one of these beautiful and unusual plants and do your part to make them more well known in your gardening circle and beyond?
This National Park Service photo shows one not-so-pleasing Persicaria, Mile-a-Minute Weed (Persicaria perfoliata). It arrived in this country in the late 1930s as a stowaway in some holly seeds from Japan and ultimately landed at a nursery site in York County, Pennsylvania. Unfortunately, the owner allowed the seedlings to mature and set seed. The vine covers the ground and climbs into trees, eventually killing them--a sort of the "Kudzu of the North." It also grows nasty little barbs, which make it necessary to wear protection during any attempt at manual eradication. So far it has spread over 300 miles from its original location.
