Wherry, commonly known as the Mountain Phlox or White-margin Phlox is native to the western region of the United States, specifically found in Arizona, Colorado, Montana, New Mexico, Utah, and Wyoming. It is also known to thrive in mountainous areas, ranging from subalpine woodlands to the higher alpine zones.
Common Names
The Phlox albomarginata M.E. Jones ssp. diapensioides is known by several common names, ranging from White-margin Phlox to Mountain Phlox, Snow White Phlox, and Diapensia Phlox. These names are given based on the plant's white-margined leaves and its natural habitat.
Uses
The Mountain Phlox has several uses in the field of horticulture. It is widely used as an ornamental plant due to its beautiful, fragrant flowers and its attractive, evergreen foliage. It is also used in landscaping due to its low maintenance requirements and its ability to grow in partial shade, making it an excellent companion plant to other garden plants. Its flowers are attractive to hummingbirds and butterflies, making it a suitable plant for creating a wildlife habitat garden.
General Appearance
The Phlox albomarginata M.E. Jones ssp. diapensioides is a low-growing perennial plant, reaching a height of up to 6 inches and a width of up to 1 foot. It produces attractive, evergreen foliage with oblong-shaped leaves that have white margins, which makes them stand out from other plants in the garden. The plant produces clusters of fragrant, white flowers with a pink or lavender-colored center, which bloom in the late spring or early summer. Each flower measures around 0.4 inches in diameter. The plant has a creeping habit and often forms dense mats on the ground, making it an ideal plant for rock gardens, ground covers, and borders.
Light Requirements
Phlox albomarginata M.E. Jones ssp. diapensioides (Rydb.) Wherry requires full sun to partial shade for optimal growth. In areas with hot summers, it may benefit from some afternoon shade to prevent heat stress.
Temperature Requirements
This plant is well-suited for USDA Hardiness Zones 2 to 8 and can tolerate a wide range of temperatures. However, it prefers cool to moderate temperatures and may struggle in excessively hot and humid climates. It is also adaptable to cold temperatures and can survive in sub-zero temperatures if given adequate protection.
Soil Requirements
Phlox albomarginata M.E. Jones ssp. diapensioides (Rydb.) Wherry prefers well-drained soil with a slightly acidic pH ranging from 6.0 to 7.0. It can tolerate a variety of soil types, including loamy, sandy, and clay soils. However, it prefers nutrient-rich soils that have good water retention capabilities. Adding compost or organic matter to the soil can improve its quality and water-holding capacity.
Cultivation Methods
Phlox albomarginata M.E. Jones ssp. diapensioides (Rydb.) Wherry, commonly known as the white-margined phlox, is a low-growing perennial plant that belongs to the family Polemoniaceae. This plant is native to western North America, where it grows in subalpine and alpine meadows, but it can be cultivated in gardens.
The white-margined phlox prefers to be grown in well-drained soil that is rich in organic matter. This plant can tolerate full sun, but it also appreciates some shade during the hottest part of the day. To grow this plant from seeds, sow them in the spring, or divide mature plants in the fall.
Watering Needs
The white-margined phlox requires regular watering during the growing season. However, it is essential not to overwater the plant, as it is susceptible to root rot. A good rule of thumb is to water the plant deeply once a week or whenever the soil is dry to the touch. During periods of drought, increase the frequency of watering, but ensure that the soil is well-drained.
Fertilization
The white-margined phlox does not require frequent fertilization, but it does benefit from occasional applications of a balanced fertilizer, such as 10-10-10. Apply the fertilizer in the spring when new growth appears, and again in mid-summer to promote blooming. Use the fertilizer according to the directions on the package, and water the plant afterward to help the nutrients penetrate the soil.
Pruning
The white-margined phlox does not require heavy pruning, but it can benefit from some maintenance pruning to encourage bushy growth and prevent it from becoming leggy. After the plant has finished blooming, trim back the stems to just above the leaves. This will help promote new growth and keep the plant looking neat and tidy. Also, remove any dead or diseased foliage throughout the growing season to prevent the spread of disease and pests.
Propagation of Phlox albomarginata M.E. Jones ssp. diapensioides (Rydb.) Wherry
Phlox albomarginata M.E. Jones ssp. diapensioides (Rydb.) Wherry can be propagated using various methods. These methods include:
Seed Propagation
One of the common methods of propagating Phlox albomarginata M.E. Jones ssp. diapensioides (Rydb.) Wherry is through seed propagation. This is done by collecting seeds from the plant when the fruits are mature. The collected seeds are then sown in a well-prepared seedbed.
Before planting, the seeds should be stratified for 6 to 8 weeks to help break their dormancy. Once the seedlings have grown to a sizable height, they can be transplanted into pots or containers and kept in a well-lit area until they are big enough to be planted in their permanent site.
Division
Another means of propagating Phlox albomarginata M.E. Jones ssp. diapensioides (Rydb.) Wherry is by dividing an already established plant. This method is best done in the early spring when the plant is still dormant.
The plant is removed from the ground, and the roots are carefully divided into sections, ensuring that every section has enough roots and shoots for the plant to grow. The divided plant can then be transplanted and watered to help it establish itself in its new location.
Cuttings
Phlox albomarginata M.E. Jones ssp. diapensioides (Rydb.) Wherry can also be propagated using cuttings. Softwood cuttings are best for this method, and they are best taken from a new growth on the plant in the early summer.
The cuttings should be approximately 2 to 3 inches long and should be taken from a healthy plant. They are then planted in a well-prepared soil mixture and kept in a warm, humid location where they can root. Once the cuttings have developed their own root system, they can be potted up and grown until they are big enough to be planted out in their permanent site.
