Phlox is a versatile and beautiful flowering plant that can thrive in a variety of conditions. While many varieties of phlox prefer full sun, there is one type, called woodland phlox, that is perfectly suited for growing under trees. This makes it an excellent choice for those shady areas in your garden where other flowers might struggle to thrive.
Woodland phlox, also known as Phlox divaricata, is a native wildflower that can be found in wooded areas across North America. It has delicate, lavender-blue flowers that bloom in the spring, adding a splash of color to the otherwise shady areas of your garden. The flowers are fragrant and attract butterflies and hummingbirds, making them a delightful addition to any garden.
One of the reasons why woodland phlox is so well-suited for growing under trees is its tolerance for shade. Unlike other varieties of phlox that require full sun to thrive, woodland phlox can handle dappled or even heavy shade. This makes it an ideal choice for planting under large trees that cast a dense shadow.
Another advantage of woodland phlox is its ability to tolerate drought once established. This is particularly beneficial in areas where the tree canopy may block rainfall from reaching the ground. Once the plants are established, they can withstand periods of dry weather without needing frequent watering. This makes woodland phlox a low-maintenance option for those hard-to-reach spots in your garden.
In terms of hardiness, woodland phlox is suitable for growing in Zones 3-8. This means it can withstand a wide range of temperatures, from cold winters to hot summers. It is a perennial plant, which means it will come back year after year, providing you with a reliable source of beauty in your garden.
I have personally grown woodland phlox under the shade of a large maple tree in my backyard. The area was previously bare and dull, but after planting the phlox, it transformed into a vibrant and colorful space. The delicate blooms added a touch of elegance to the otherwise shady corner, and the fragrance attracted butterflies and hummingbirds, creating a lively and enchanting atmosphere. It was truly a joy to see the flowers thrive in the shade and bring life to an otherwise neglected area of my garden.
To successfully grow woodland phlox under trees, there are a few key considerations to keep in mind:
1. Choose the right spot: Look for an area under the trees that receives dappled or filtered sunlight. Avoid planting in areas that are in deep, dense shade as this may inhibit the plant’s growth and flowering.
2. Prepare the soil: Woodland phlox prefers well-drained soil that is rich in organic matter. Before planting, amend the soil with compost or aged manure to improve its fertility and drainage.
3. Water regularly during establishment: While woodland phlox is drought-tolerant once established, it is important to water regularly during the first growing season to help the plants establish a strong root system. Water deeply but infrequently to encourage deep root growth.
4. Mulch to conserve moisture: Apply a layer of mulch around the plants to help conserve moisture and suppress weed growth. This will also help to regulate soil temperature and maintain a more consistent moisture level.
5. Divide and transplant as needed: Over time, woodland phlox may become overcrowded and benefit from division. Divide the plants every few years in early spring or fall to maintain their vigor and promote better flowering.
Woodland phlox is a fantastic choice for growing under trees. Its tolerance for shade, drought resistance, and attractive blooms make it an excellent addition to those challenging areas in your garden where other flowers may struggle. By choosing the right spot, preparing the soil, and providing adequate care, you can create a beautiful and thriving woodland phlox garden under your trees.
