Perennial, spreading by seed and rooting of stems. It is said to have been on the ground at the entrance to the cave where Christ was laid to rest and when he stepped out onto it he blessed it for being soft. This gives the plant special significance and could relieve the pain of childbirth if placed under the right knee. Also women would hold a piece in their mouth when kissing a suitor to ensure the relationship would be long-lasting or drinkind an infusion would attract a partner. Faries were accused of spiriting people away so placing some over the door would keep them out.
It forms a dense mat close to the ground. The very fine, grass-like leaves can be mistaken
for a moss. Very invasive and a problem in close cut
lawns - raise the mower to allow the grass to outgrow
it. Watch out for it on the surface compost of new plants (discard the top few centimetres before planting).
Seed can be spread while mowing and carried on soles of
shoes. Has been suggested as a non-grass lawn, but
unless you want complete garden coverage, avoid.
