Some of mine Phlox varieties are still flowering though, they are slowly fading away. It's been raining for days and water certainly has ruined the flowers. The weather for the next week seems promising though, it will be raining again during the following weekend and the ground is very wet to do anything in the garden. I haven't finished planting my "hosta garden" or the border in my friend's garden.
Phlox paniculata (I cannot tell which variety is which anymore)
This is a genus of herbaceous perennial and annual plants of the family Polemoniaceae. It is native to North America, and there is one species in Siberian tundra. Phlox grows in woodland and prairie. It flowers, depending on the species, in spring, summer or autumn.
In our gardens, there is mostly Plox paniculata to be seen in the flower beds. Low growing cushion-like Phlox subulata finds it's place in the rock garden.
This is one of the most beautiful summer perennials. It may have white, pink, violet, blue or bright red flowers, often with an "eye" in the middle. Many of the flowers are scented. There are also cultivars with variegated leaves.
Phlox maculata 'Natasha'
Depending on cultivar, Phlox paniculata is up to130 cm tall, and therefore is used as background plant in the borders. A good air circulation is needed to keep them healthy. Powdery mildew is most common disease that occurs, causing the leaves to drop off and leaving the stems bare.
Divide them every three years in spring before they start to grow. Most perennials benefit from division to keep them in shape and within the place.
Tall phlox grows the best in a sunny position but, it will tolerate light shade. The soil should be moist so water it in summer during dry spells. Avoid watering over leaves. To prolong the flowering time, cut a few shoots of the clump to one third. They are supposed to flower again later on.
Except by division, Phlox can be propagated by stem cuttings that bear no flowers. Take them in summer.
Phlox stolonifera 'Red Wing' in my rock garden.
Low growing species like Phlox subulata, Phlox stolonifera or Phlox divaricata make dense cushions and love sunny positions. They are suitable for rock garden. They will also tolerate dry soil. They usually flower early in the spring.
The leaves of these species is evergreen or semi-evergreen. Except in the rock garden they can be used as edging plants for borders and containers or cascading plant for walls.
They can be propagated by division.
After flowering, shear the stems to one third to promote new shoot growth.
