SAPONARIA OCYMOIDEA PINK (500 SEEDS) PERENNIAL FLOWER!
Saponaria is a superb flowering, pretty little plant that makes a low carpet for ground cover or for rock features. The plants form a mound of bright-green leaves, smothered by starry bright-pink clusters of flowers in late spring.
Use as a ground cover in pockets in paving, as an edging in the sunny border or allow it to trail over the sides of raised beds and low walls for continuous summer colour. It is also worth considering for containers and for green roofs.
In the rock garden it will spill down sunny slopes and flow around rocks, helping to blend them into the landscape. It makes a great nursery plant for areas where other, slower growing plants are to be grown, preventing weeds while new plants are establishing.
Saponaria can be used to overplant spring bulbs and is one of the easiest ground covers. Hardy to about -15°C (5°F), it is drought tolerant once established.
Sowing: Sow in spring or autumn.
Seed can be sown at most times of year, apart from the very hottest and coldest months. The ideal temperatures are around 15 to 20°C (59 to 68°F). They are best sown early, from November to March in gentle heat; the plant will be fully established before the following winter. They can be sown in June to July if placed out of direct sun. Germination usually takes 14 to 30 days. Sowing to Germination: 4 to 8 weeks. Germination to Transplant: 4 to 6 weeks.
Fill cells or pots with a free draining seed compost, stand the containers in water to moisten thoroughly, then drain. Sow the seeds on the surface of the compost. The seeds need light to germinate so ‘Just cover’ with the lightest sprinkling of sieved soil or a fine layer of vermiculite.
Make sure the compost is moist and not wet. Use a propagator or seal in a polythene bag until after germination which usually takes 14 to 30 days at 15 to 20°C (59 to 68°F).
Saponaria usually germinate within 30 days, but if there is no germination, put the container somewhere cold, at around -4 to 4°C ( 24 to 39°F) for 2 to 4 weeks. Then bring back into warmth, the change in temperature will trigger germination.
Remove the polythene bag once the first seedlings appear. When they are large enough to handle, transplant them to 7cm (3in) pots to grow on. Remember to hold the seedlings by the leaves and not the stem. Plant out into their permanent positions in late spring or early summer, after the last expected frosts. Space 40 cm (16in) apart into a well drained garden soil in full sun.
Cultivation:
Saponaria prefers full sun. Winter survival is dependent on the plant growing in well-drained soil. Do not fertilize during growing season. Bone meal worked into surrounding soil in early spring is all they need.
Cut plants back by about half after they are finished blooming to maintain a compact habit. This may also provide the added benefit of sporadic repeat bloom in late summer.
It readily reseeds itself and will spread rapidly in a favourable situation. Prompt shearing as the flowers fade keeps it tidy and prevents reseeding.
Clumps may be easily divided in late summer or early spring.
