How to Grow Pussytoes
Plant Pussytoes in full sun and gritty well-drained soil, spaced 8 to 12 inches apart. The low silver-leaved groundcover spreads by runners to form a tight mat that handles drought, lean soil, and foot traffic. Skip fertilizer entirely, since rich soil produces floppy growth and rots the crown.
Where to plant
Pussytoes is a low alpine perennial groundcover for USDA zones 3 through 8. The plant reaches about 2 to 4 inches tall with a 12 to 18 inch spread, slowly forming a dense silver-leaved mat. Native to mountainous and northern habitats, it thrives in lean rocky soil and tolerates conditions that kill most ornamentals.
Sun
Full sun, meaning six or more hours of direct light a day. The silver hairs on the leaves develop best in bright sun and the foliage looks washed-out green in shade.
In zone 8, light afternoon shade through the hottest part of summer keeps the foliage fresh, but plants further north prefer all-day direct sun.
Drainage
Well-drained gritty soil is essential. The plant rots quickly in standing water, especially in winter. Dig a one-foot test hole and fill it with water. If it sits overnight, pick a different spot or build a raised gravel bed. Rocky banks, sloped sites, and sandy ground all work better than rich garden soil.
Soil
Lean gritty soil amended with sharp sand or fine gravel is ideal. Skip compost, peat, and any organic amendments. Pussytoes evolved on alpine scree and grows weak and floppy in rich ground. A gritty mineral soil also helps the crown stay dry through wet winters.
Space
Space plants 8 to 12 inches apart for groundcover use. The plants knit together within a season or two through runners that root where they touch soil. Tighter planting produces faster coverage but increases crown-rot risk if any one plant gets shaded.
How to plant
Plant Pussytoes in early spring after the last frost or in early fall while the soil is still warm. Container plants are usually sold in small pots and transplant easily. Spring planting establishes faster overall because the plant has the full growing season to spread before winter.
-
1Dig a shallow hole About twice as wide as the root ball and the same depth. The fibrous root system is shallow, so width matters more than depth.
-
2Mix sand or fine gravel into the area If the native soil is heavy clay, work a few inches of sharp sand or fine gravel into the top 6 inches of soil. This is one of the few cases where amendment helps, since the plant needs grit for drainage rather than nutrients.
-
3Slide the root ball out gently Loosen any tightly circling roots without breaking the root ball apart. The roots are fine and damage easily.
-
4Set the crown above soil level Position the root ball so the top sits slightly above the surrounding ground. A high crown rots far less often than a buried one in this plant.
-
5Backfill and tamp lightly Fill the hole back up with the original soil mixed with extra grit. Tamp gently to eliminate air pockets without compacting the soil.
-
6Water once and mulch with gravel Soak the root zone once at planting, then mulch the entire planting area with a thin layer of pea gravel or coarse sand. Gravel mulch keeps the crown dry and reflects light up into the foliage. Avoid bark mulch or compost top-dressings.
Watering and feeding
Watering
Water deeply once a week through the first growing season while the runners spread and root in. Soak the root zone rather than splashing the foliage.
After year one, Pussytoes is exceptionally drought-tolerant. Most years need no supplemental water at all. A deep soak every three to four weeks during extreme summer dry spells keeps the mat looking fresh. Overwatering an established mat kills it faster than drought does.
Feeding
Skip fertilizer entirely. The plant blooms and spreads better on lean soil than rich soil. Fertilizer pushes floppy lush growth that rots in winter.
Avoid lawn fertilizer drift, which can wipe out a Pussytoes patch within a season. A thin top-dressing of grit or sand in early spring is the only amendment the mat actually wants.
Pruning and maintenance
Pussytoes needs almost no pruning in the conventional sense. The most useful maintenance is light shearing of spent flowers and occasional thinning of the mat where runners outgrow their space.
Deadheading flowers
After the spring flowers fade, shear the flower stems back to the foliage line with sharp scissors or hedge shears. The plant looks tidier and the energy goes back into the mat rather than seed production.
Thinning the mat
Every two to three years, the center of the mat thins out as the runners spread outward and the older middle dies back. Lift the live outer sections in early spring, replant smaller divisions on fresh ground, and discard the dead center.
Runners that creep beyond their intended space can be cut off with a sharp spade and either composted or replanted as new starts.
Blooming and color
Pussytoes is grown for the silver foliage and the fuzzy white or pale pink flower clusters held above the mat on short stems in spring. The flower clusters resemble small cat's-paw pads, which is where the common name comes from.
Bloom timing
Flowers open in mid to late spring, usually May or June depending on the zone, on stems 4 to 10 inches tall above the silver mat. Each cluster lasts about two weeks, and the overall bloom window runs three to four weeks. Male and female flowers occur on separate plants, with female plants typically pinker than the white-tipped males.
The silver foliage
The real long-season feature is the silver-gray foliage, which holds color from spring through fall. The leaves are covered in fine white hairs that reflect light and give the entire mat a soft silvery cast. The color contrasts beautifully against dark mulch or brown stone in a rock garden.
In zones 6 and warmer, the foliage is semi-evergreen and holds its silver color through mild winters. Colder zones lose the leaves but the plant resprouts vigorously each spring.
Walking on the mat
An established Pussytoes mat tolerates light foot traffic. Use the planting between stepping stones or along a path edge where occasional stepping is fine. Heavy or frequent traffic compacts the crown and thins the mat, so use a tougher groundcover for the main path itself.
Common problems and pests
Pussytoes is genuinely tough in the right site. Most trouble involves overwatering, rich soil, or shade rather than pests or diseases.
Crown rot in summer or winter
Almost always overwatering or poor drainage. Cut watering back, scrape any heavy mulch away from the crown, and check that the soil drains freely. Plants in clay benefit from being replanted onto a raised gravel bed. Skip overhead irrigation entirely and water only the soil.
Loss of silver color
Caused by too much shade or too much fertilizer. Move the plant to a sunnier spot in fall and stop any feeding. The new silver foliage takes a few weeks to develop after the move.
Center of mat dies out
Normal aging behavior in an established mat. Lift the live outer sections in early spring, divide into smaller pieces, replant on fresh gritty ground, and discard the dead center. Dividing every 2 to 3 years prevents the problem from spreading.
Floppy stretched growth
Too much shade or rich soil. The plant needs full sun and lean ground to stay compact. Move shaded plants to brighter spots and skip any feeding. A light shearing after spring bloom encourages tighter regrowth.
Slugs and snails damaging foliage
Ragged holes in the leaves and slimy trails through the mat, mostly in damp shaded areas. Hand-pick at night with a flashlight. Iron phosphate slug bait scattered around the mat in early spring is pet-safe and reduces the population. Improving drainage and increasing sun exposure also makes the spot less hospitable.
Spider mites in dry hot weather
Tiny webs and stippled silvery leaves in extended dry spells, especially in inland gardens. Hose the foliage down thoroughly to dislodge them. The plant usually outgrows light infestations on its own once cooler weather returns.
Aggressive spread into neighboring plants
The runners creep outward and can crowd out small neighboring plants. Cut runners with a sharp spade where they cross the desired boundary, and either compost the cuttings or transplant them as new starts. Setting a low metal edging along the planting bed keeps the mat contained.
Fewer flowers over time
Usually a sign the mat needs dividing. An old mat with a thinning center produces fewer blooms each year. Lift and divide in spring, and the divisions resume normal flowering within one season.
Patchy growth where the mat meets shade
The plant grows fast in sun and slows dramatically in shade. Patchy growth at the shaded edge of a mat is normal. Either extend the sunny zone by removing overhanging branches, or accept that the mat will be denser on the sunny side.
