Phlox - Alpine species
Phlox stolonifera is a good subject for either growing in pots in an alpine house, or for use as a ground cover plant.
It is a drought tolerant herbaceous perennial that grows to around 250mm (10") high with a spread of 300mm (12"), and flowers from late May into June.
Take 50mm (2") basal cuttings and insert the cuttings into pots/trays filled with equal parts (by volume) peat and river sand, then place in a cold frame to root.
When rooted pot up into 75mm (3") pots of potting compost and grow on in the cold frame until planting out next April.
Plant out in a fertile sunny spot between now and April the following year.
