Phlox paniculata 'All in One'
border phlox
- Position: full sun or partial shade
- Soil: fertile, moist but well-drained soil
- Rate of growth: average
- Flowering period: June to September
- Hardiness: fully hardy
The pale lilac petals of this recently introduced cultivar have broad white margins on either side, creating a soft bi-coloured effect from midsummer to early autumn. Place it with other pastel shades toward the middle of a herbaceous border, and give it plenty of room to allow its lax habit to mingle with its neighbours. It is tolerant of full sun or partial shade as long as the soil remains reliably moist throughout summer. - Garden care: Support with bamboo canes, brushwood or ring stakes before the flowers appear. Phlox are greedy plants, so apply a mulch 5-7cm (2-3 in) deep of well-rotted garden compost or manure in early spring. Shear off the spent flowers to prevent reseeding. If the leaves show signs ofpowdery mildew, cut down to the ground and dispose of the affected foliage, but do not compost it. Clear away the debris around the plant to reduce the chances of reinfection. Cut down to the ground in autumn. Lift and divide large clumps in autumn or spring.
