‘Paloma’ is a popular cultivar of Phlox paniculata, commonly known as garden phlox. This perennial is a favorite in many gardens due to its attractive pure white blooms and pleasant fragrance, bringing a classic, bright touch to summer landscapes.
Understanding Paloma Phlox
Phlox paniculata ‘Paloma’ exhibits an upright growth habit, typically reaching heights of 2 to 4 feet and spreading 2 to 3 feet wide. Its sturdy stems support dense clusters of fragrant, pure white flowers, often with a subtle green eye. These large, domed blooms appear from mid to late summer, extending their display into early fall.
Planting Paloma Phlox
The ideal times for establishing ‘Paloma’ Phlox are in spring, after the last frost, or in early fall, at least a month before the first frost. These plants thrive in full sun (at least six hours of direct sunlight daily), though they can tolerate some afternoon shade in hotter climates. Optimal soil conditions include well-draining, moist, and nutrient-rich soil with a neutral pH.
Before planting, loosen the soil to a depth of 12 to 15 inches and incorporate a 2 to 4-inch layer of organic matter like compost. Dig a hole approximately twice the diameter of the plant’s root ball, ensuring the top of the root ball is level with the soil surface. Space ‘Paloma’ Phlox about 18 inches apart for proper air circulation. After planting, water thoroughly.
Ongoing Care for Paloma Phlox
Adequate sunlight is important for healthy flowering and to help prevent diseases; aim for at least six hours of direct sun exposure daily. While ‘Paloma’ Phlox can tolerate some partial shade, particularly in hot southern regions, reduced light can decrease bloom quantity and quality while increasing susceptibility to issues like powdery mildew. Good air circulation around the plants is also beneficial.
‘Paloma’ Phlox requires consistent moisture, especially during dry periods, with an inch of water per week generally sufficient during the growing season. Water deeply at the roots rather than overhead to encourage strong root growth and minimize foliage dampness, which can promote fungal diseases. Early morning watering is ideal as it allows foliage to dry before nightfall. Applying a 2 to 3-inch layer of organic mulch around the base of the plants helps retain soil moisture, regulate soil temperature, and suppress weeds.
For soil health, a light application of balanced fertilizer or a fresh layer of compost in early spring is sufficient. A balanced fertilizer, such as a 10-10-10 blend, provides nutrients for robust growth and abundant blooms. This feeding supports the plant as it emerges from dormancy, promoting strong roots and vibrant foliage. Some gardeners apply a second, lighter dose after the first flush of flowers to encourage reblooming.
Deadheading spent blooms can prolong the flowering period and improve the plant’s appearance. This practice also prevents self-seeding, which helps maintain cultivar characteristics. For overall plant health, cut back stems to about 1 to 2 inches above the soil after the first killing frost in the fall, or in early spring before new growth appears. Thinning about one-third of the shoots in early spring can improve air circulation and reduce disease risk.
Addressing Common Problems
Garden phlox, including ‘Paloma’, is susceptible to powdery mildew, a common fungal disease characterized by white, powdery spots on leaves and stems. Prevention is key, and strategies include ensuring good air circulation through proper plant spacing and thinning overcrowded clumps. Watering at the base of the plant instead of overhead also helps, as damp foliage encourages fungal growth.
If powdery mildew appears, remove infected plant parts and dispose of them away from the garden to limit spread. For treatment, a homemade spray of one tablespoon of baking soda and half a teaspoon of liquid soap mixed in one gallon of water can be applied weekly to the undersides of foliage. Horticultural oils or copper-containing fungicides are also options for active outbreaks. Other potential pests include spider mites and aphids, which can be managed with appropriate horticultural practices.
Using Paloma Phlox in Your Garden
‘Paloma’ Phlox is versatile, suitable for various garden designs. Its pure white blooms create a striking contrast in perennial borders or cottage gardens. It works well as a background plant due to its height or grouped with other perennials for mass color. The fragrant flowers also make ‘Paloma’ Phlox an excellent choice for cut flower arrangements, bringing its beauty indoors.
