Phlox paniculata | ArgosyRegular price $15.00 Save $-15.00
Phlox paniculata Argosy is a showy pretty pale lavender perennial scented Phlox with a white eye that is considered to be a garden classic and an essential element of the summer border. The flowers not only look beautiful, but butterflies and birds adore them due to their nectar.
This plant grows in an upright clump of erect branches and will perform well in a full sun position. Phlox paniculata likes a well drained soil as well as good air circulation as plants can succumb to powdery mildew, therefore watering at the base is preferable to watering overhead. This plant can be a bit fussy to grow, in bags so never seems to look that great, but once established in the garden it is fine - we also add gravel in when planting to help with drainage.
Powdery Mildew can be helped with a mixture of 1 Tablespoon of Baking Soda and 1 teaspoon of horticultural oil or plant soap in about 3.5 litres of water. Just spray in the morning before the heat gets on the plant as some oils can burn the leaves. Spray at weekly intervals.
Plants are dormant in winter so die back to re-emerge in spring. Flowering occurs in summer. To encourage reflowering be sure to either deadhead or use your flowers as cut flowers as they are great in a case.
The long, stiff stems of garden phlox are easy to arrange in a vase, where they complement and help hold up other flowers such as dahlias and lilies. Be sure to cut some stems while some of the flowers are still in bud as this will extend their vase life. Deadheading or picking flowers for the vase will help to promote new flowers.
Plants can be split once clumps have become established and this can be done in autumn.
We have other varieties of both perennial and annual phlox which you can find here.
