Phlox, a plant native to North America, is a must-have for any garden! With very little care, gardeners will be rewarded with brilliant displays of fragrant flowers. Phlox is also known to attract butterflies!
The majority of phlox are grown as perennials, but there are some that are annuals.With various bloom times, colours, and sizes available, there is a phlox or two to suit your design needs! Flowers come in shades of red, white, pink and purple. Tall garden phlox with their large, fragrant flowers would be ideal as borders, adding height and beauty to the landscape, while low-growing or creeping phlox would make wonderful ground covers. Some varieties can even be grown in containers.

Here are some tips on growing phlox:
- Phlox can be grown from cuttings or from seed. Depending on the variety, phlox can be planted in the spring or fall.
- Plant in full sun in rich, well-draining soil. Amend heavy, clay-like soil with compost and peat moss, if necessary. Space plants 1-2 feet apart.
- Mulch young plants with bark or small wood chips to suppress weeds, retain soil moisture and to keep soil cool.
- Water regularly, especially during hot days.
- Phlox can be susceptible to powdery mildew. Choose disease-resistant plants to avoid the risk of disease. If older plants are becoming overcrowded, thin out stalks and foliage to improve air circulation.
- Deadhead (remove spent blooms) to extend the blooming period.
- Pinch back tall cultivars early in the summer to encourage more blooms.
- Clumps can be divided in the fall or spring. To keep plants healthy and vigorous, mature phlox should be divided every 3-4 years.
