2205 - DIANTHUS AMURENSIS - SIBERIAN BLUES -
This charming hardy perennial forms neat mounds of blue-grey evergreen foliage that contrast beautifully with the lavender blue flowers. Dianthus amurensis ‘Siberian Blue’ blooms over a long period throughout summer on resilient, dense plants with a vigorous habit. Perfect for planting in rockeries, alpine troughs and at the front of borders where it will form useful low maintenance ground cover. Height: 38cm (15"). Spread: 30cm (12").
Sow Dianthus seeds indoors from August to September or February to June on the surface of lightly firmed, moist seed compost in pots or trays and cover with a fine sprinkling of compost or vermiculite. Place in a propagator or seal container inside a polythene bag and keep at a temperature of between 15-20C (59-68F). After sowing, do not exclude light as this helps germination. Keep the surface of the compost moist but not waterlogged; germination usually takes 14 - 30 days.
When seedlings are large enough to handle, transplant into 7.5cm (3") pots and grow Dianthus plants on in cooler conditions. Gradually acclimatise pinks to cooler conditions for a few weeks before planting out after all risk of frost. Plant Dianthus at a distance of 23cm (9") apart on any fertile, well drained soil in full sun.
