Sometimes you need something different to liven up the shade tapestry of ferns, hostas and hellebores. Painter’s Palette knotweed (Persicaria virginiana ‘Painter’s Palette’) might be just the answer. This isn’t the highly invasive knotweed that threatens to engulf both ornamental and native plantings, but a better-behaved relative. Having said that, it is still quite vigorous and spreads by underground rhizomes as well as seed, especially in moist soil. I have found that in drier conditions it spreads very little, so choose your site wisely and consult your local Extension office if in doubt.
Why we like it
Mottled green and cream foliage is splashed irregularly with raspberry shades, and most leaves have a burgundy chevron. Painter’s Palette forms a mound of foliage, and an abundance of wiry stems of unusual red flowers rises above in midsummer. As an herbaceous perennial, it will die down in winter, which allows ephemeral spring-blooming bulbs to be tucked in underneath.
While suffering mild slug damage it is mostly ignored by deer and rabbits and is hardy in USDA zones 5-9. It copes with clay soil and thrives in moist conditions but never gets watered in my woodland gardens and does just fine so appears to be reasonably drought tolerant providing the soil holds adequate moisture.
Recommended for partial sun it will take more sun if kept well watered,
How to use it
Of course the question is, what other plants can we combine with it to really show it off? Well there are plenty of options to choose from. Seeking out other foliage plants that echo the creamy tone is a good way to start then highlight the rose chevron detail with an accent flower or leaf.
In the example below the green and cream are repeated by two other adjacent plants while the raspberry chevron is picked up by a planting of magenta phlox in the distance
Seattle designer Daniel Mount has got a remarkable eye for color and detail, weaving plants together into luxuriant tapestries that seduce the unwary visitor. How can you resist running your fingers through the cascading waterfall of Japanese forest grass (Hakonechloa macra ‘Aureola’) or testing the springiness of the perfectly clipped variegated boxwood? This artistic combination is discussed in more detail here and we have several more of Daniel’s designs to share with you in our upcoming book Gardening with FOLIAGE FIRST (Timber Press, January 2017).
Thomas Vetter is another Pacific Northwest gardener with an uncanny ability to shoehorn an abundance of plants into a relatively small space yet do so in a strategic way to create layers of contrasting and complementary foliage with floral and other artistic accents added as precisely placed punctuation points.
Painter’s Palette knotweed brightens up a corner of his front garden, illuminating a purple smoke bush while adding a stage upon which the pineapple lily (Eucomis ) can truly show off her shapely form and flowers. See how those burgundy stems draw the eye to the chevron detail on the knotweed? The faded allium seedheads add a delightful softness to the composition, juxtaposed with the bronze succulent foliage of the pineapple lily and mimicking its star shaped flowers.
Nearby this knotweed variety is given a new twist by introducing the red bell-shaped blooms of a flowering maple (Abutilon) and flirty Hot Lips sage (Salvia microphylla ‘Hot Lips’) both of which serve to really pull out its rosy foliage markings. Balancing the wispiness of the Hot Lips sage, a variegated agave adds bold texture and form while Fire Power heavenly bamboo (Nandina domestica ‘Fire Power’) transitions the color palette into more golden hues.
When viewed from a different angle, one can better appreciate the clever use of contrasting leaf texture while repeating the key colors in this vignette.
