About

Saxifraga 'Portae' (x _fritschiana_) is a mat-forming, evergreen saxifrage that forms a low carpet of foliage. It flowers April to July. Plant it in full sun or partial shade on well-drained chalk, loam or sandy soils with neutral to alkaline pH. It is hardy (H5) and suits rock and gravel gardens, or patio containers.

About the genus

Saxifraga is the largest genus in the family Saxifragaceae, containing about 473 species of holarctic perennial plants, known as saxifrages or rockfoils. The Latin word saxifraga means literally "stone-breaker", from Latin saxum + frangere. It is usually thought to indicate a medicinal use for treatment of urinary calculi, rather than breaking rocks apart.

In the garden

Saxifraga 'Portae' (x _fritschiana_) is a mat-forming member of the Saxifragaceae that holds evergreen leaves close to the ground. Flowering runs April to July, when blooms sit above the foliage and add seasonal definition to a gravel or rock planting. Its low profile makes it useful where a spreading, ground cover habit is required. Choose a site in full sun or partial shade with very free-draining soil; chalk, loam or sand on neutral to alkaline pH suit it best. The plant tolerates both exposed and sheltered positions and, with an H5 rating, is winter-hardy across most of the UK when planted in a suitable, well-drained spot. Avoid waterlogged soil, which undermines root health more than exposure to wind or sun. Saxifraga 'Portae' works where a compact, evergreen carpet is needed: in crevices of a rock garden, over gravel beds, and in shallow patio containers where drainage is brisk. Plant into shallow pockets or gritty compost and position on a south- or west-facing aspect for best flowering display. Allow the mat to fill gaps between stones so it reads as living grout that blooms each spring and early summer.
