Sowing: Sow from early spring to early summer, February to May
Seeds can be stated early indoors in late winter to early summer or can be sown directly outdoors where they are to flower. Seeds can be also sown in autumn, they make fine spring flowering pot plants for the cool greenhouse. 65 days sowing to flowering.
Choose a sunny, well-drained site, and amend it with compost or well-rotted manure. Direct sow 6mm (¼in) deep in spring, as soon as the ground can be worked. Pinch seedlings when they are 8cm (3in) tall to promote branching, and thin to 20cm (8in) apart. Maintain soil moisture all season, and fertilize monthly with a water-soluble fertilizer, following label directions.
Sow in spring about 5 to 7 weeks before the last frost date (around May). Sow 1.5mm (1/16in) deep in into pots or trays containing John Innes or similar free draining seed compost. Make sure that the compost is moist but not wet and cover or seal in a polythene bag, exclude light until after germination which usually takes 10 to 21 days at 13 to 15°C (55- 60°F).
Transplant when large enough to handle into 8cm (3in) pots to grow on. Pinch out the growing points when 8cm (3in) high to ensure a bushy habit.
Annual phlox seedlings should be hardened off before transplanting to the garden. Put them outdoors in a sheltered spot for a few hours each day, gradually increasing their time outdoors over the course of a week. Plant out 20cm (8in) apart into rich well drained soil and full sun.
Deadhead blooms to encourage flowering. Shear plants back if they become leggy. It may look ragged in hot weather. Keep it well watered and it will probably revive in autumn's cooler temperatures. Remove plants after frost
Cut flower stems can be harvested, when first flowers per stem are just open. Remove the bottom leaves. Vase life: 10 to 14 days.

Phlox is a genus of 67 species of annual or perennial flowering plants, most species are native to temperate North America but a few species are also from north-eastern Asia. Some species flower in early spring while others flower in summer into autumn. They are found growing in diverse habitats from alpine locations to open woodlands and prairies. Flowers range in colour from pale blue to bright red to white. Some species such as Phlox glaberrima (Smooth Phlox) grow to 1.5 m tall, while others, such as Phlox stolonifera (Creeping Phlox), form low mats only a few centimetres in height.
Several species of phlox are commonly cultivated in gardens. Most cultivated phlox, with the notable exception of Phlox drummondii (Drummond phlox), are perennial.
The plant is often confused with look-alike native hesperis matronalis, Dames Rocket, but they can be easily identified by their flowers, phlox have five petals, Dames Rocket has only four.
Linnaeus, the father of taxonomy, took the name phlox from the Latin for a flame-coloured flower, which is from the Greek φλόξ, (or flóga) meaning 'flame'.
Phlox drummondii, commonly called Drummond's Phlox is named for the the English plant explorer Thomas Drummond. He discovered the plant in Texas, USA in 1835, Naturally occurring in rose-red, this US native phlox is today established along sandy roadsides all the way from Canada into central Florida.
Phlox is pronounced flocks, the plural for phlox is phlox or phloxes.
