Antennaria plantaginifolia

Antennaria plantaginifolia, also known as plantain-leaved pussytoes, is a small perennial groundcover plant valued for its ability to thrive in poor and dry areas of the garden, where other plants struggle to survive. Not only is it very hardy and undemanding, it also forms a beautiful carpet of silky, soft, grey-green rosettes, and produces small cream-coloured pompom-like flowers on short stems in spring. It is lovely in rock gardens, at the base of hedges, and can also be used to complement more showy plants in flower beds.

Antennaria plantaginifolia is a perennial plant in the Asteraceae family, native to eastern North America. It can be found in a variety of sunny and often dry habitats, such as hillside meadows, forest clearings in mountains, wooded slopes, cliffs, trail edges, disturbed areas, thickets, pastures, and abandoned fields. It is an opportunistic plant that thrives in poor, rocky, limestone, or sandy soils, and it prefers to establish itself after a fire has passed through the area, as it avoids competition from other species.

It spreads from a stoloniferous base, with slender, prostrate stems that root upon contact with the ground, allowing the plant to expand into a minimum 80cm (32in) wide carpet over time. It develops small rosettes of oval to rounded leaves, measuring 3.5 to 7.5cm (1 to 3in) in length with a similar width, with 3 to 7 prominent veins. The upper surface of the leaf is green in colour, covered in short silvery bristles that give it a greyish hue. The undersides of the leaves also have numerous silvery bristles. These leaves persist to varying degrees depending on the severity of winter. Flowering occurs in May-June, depending on the climate. Floral stems with tiny leaves emerge from the rosettes, about 15cm (6in) above the ground. At the top, small clusters of 3 to 7 tiny inflorescences, organised into heads, appear. Each head consists of numerous tiny flowers surrounded by cream-coloured bracts covered in shiny bristles. This species has both male and female plants, and seeds will only develop from the female flowers in the presence of male plants.

Valuable in areas of the garden where the soil is poor and dry, Antennaria plantaginifolia is one of those plants, like sedums or basket-of-gold, that are well-adapted to Spartan conditions. They do not thrive in overly wet or fertile soils, as they will quickly be overtaken by larger, more voracious neighbours. Pair it with grey-leaved plants that often tolerate similar challenging growing conditions, such as cotton lavenders, curry plant (Helichrysum italicum), pasque flower, or pearly everlasting. It thrives in rock gardens and on dry slopes, and it can also be planted above retaining walls.
