Quote above UK site....
"A very low cousin to the familiar Baby's Breath of florist shops, this species is well suited to growing in the rock garden, rock wall or alpine trough. It forms a compact tuft or mound of small, rounded fresh green leaves, with taller branching stems that are studded with starry flowers from late spring into the summer. Petals are white with tiny pink veins. Requires a well-drained site. Clumps may be divided in spring or early autumn. Drought tolerant. Flowers are attractive to butterflies. May remain evergreen in mild winter regions."


Quote Gardens World. UK....
"Mouse-eared gypsophila, Gypsophila cerastioides, is a dwarf, semi-evergreen plant with a creeping habit. Green-grey, hairy leaves contrast with masses of small white trumpet-shaped flowers in spring and summer, which are beloved of pollinators.

This tough little plant is drought tolerant, and is perfect for growing in alpine gardens, rockeries, containers and even in gaps in walls and paving."
