Phlox are a herbaceous perennial. They are very easy to care for. In fact, they almost care for themselves. Once they are established, they will continue to come up each spring. They like some extra water if the rainfall is less than an inch per week during the summer. It is best to water them in the early morning so that the plants can dry before dark. One of the most common diseases of phlox is fungus. Watering the plants later in the day might lead to fungus growth. The leaves will turn white as if covered by dust. Although unsightly, this does not seem to harm the plant however and the following year the fungus is gone and the plants are fine. Phlox attract butterflies and hummingbirds. One of my primary reasons for having these plants in my garden!
I have three different colours of phlox. They are all perennial and grow up to 3 or 4 feet. The white ones are growing in the very back of the garden and are in deep shade now that other plants have grown up around them. I will have to transplant those next spring or I might lose them. I could not get a photo of them because they were too far back. I also have a light pink one that is very pretty. It has a darker rose colour in the centre of each flower. This plant is still small. I planted it a couple of years ago. This one is definitely a P. paniculata.
