Common Names of Oxytheca parishii Parry
Oxytheca parishii Parry is commonly referred to as Parish's oxytheca, Parish's oxytheca nuttallii, and Parish's pink.
Appearance of Oxytheca parishii Parry
Oxytheca parishii Parry has tiny pinkish-white flowers and clumps of slender leaves reaching approximately 40 cm (16 in) in height. This plant has multiple stems that are almost entirely hairy with repeated branching from the base, which gives the plant a bushy appearance. The flowers of this plant are rather small and can be seen blossoming in the late spring and summer months. The flowers are an important feature of the plant as they attract bees and other important pollinators.
Uses of Oxytheca parishii Parry
This plant is used ornamentally in xeriscapes and rock gardens in areas with dry and rocky conditions. Home gardeners who want to add a unique native species to their garden may find this plant a good fit as it requires minimal maintenance. The plant is also used medicinally; the Kumeyaay tribe used the roots of Oxytheca parishii Parry to treat coughs and colds.
Growth Conditions for Oxytheca parishii Parry
Oxytheca parishii Parry, also known as Parish's oxytheca, is a perennial herbaceous plant that is native to the Great Basin and Mojave Desert of the western United States. Here are some typical growth conditions favorable for this plant:
Light Requirements
Oxytheca parishii Parry thrives well under full sunlight exposure but can also tolerate partial shade. This plant requires a minimum of six hours of direct sunlight exposure per day to grow correctly. Inadequate sunlight can cause the plant to become leggy, weak, and more susceptible to pests and diseases.
Temperature Requirements
The plant grows best in regions that have hot and dry summer temperatures, with a minimum daytime temperature of 80°F and a minimum nighttime temperature of 60°F. It is relatively tolerant of cold temperatures but will mostly stop its growth during the cooler winter months when the temperature drops below 40°F.
Soil Requirements
Good soil drainage is crucial to the successful growth of Oxytheca parishii Parry. The plant prefers well-drained, sandy or gravelly soil that is slightly alkaline. This species can grow well in soils that are nutrient-poor, but it still thrives better in soils that are organically enriched. A pH range of 7.2-8.8 is considered best for its growth.
In conclusion, Oxytheca parishii Parry is a perennial plant that prefers dry and hot growing conditions, full sunlight exposure, and well-drained, organically enriched soil. Once established, Oxytheca parishii Parry can be a low maintenance plant, making it an excellent choice for people interested in gardening with natives.
Cultivation Methods for Oxytheca Parishii Parry
Oxytheca parishii Parry is a drought-tolerant plant species that thrives in well-draining soil that has a pH range of 6.5 to 7.5. It is preferable to cultivate this species in rock gardens, xeric, or wild gardens where the soil is sandy with some organic mixture. The plant prefers full sunlight exposure, but it can also tolerate partial shade.
Watering Needs
When watering Oxytheca parishii Parry, ensure that the soil is dry and avoid overwatering the plant. Water the plant occasionally, once after every two to three weeks, especially during the growing season of spring and summer. During the plant's dormancy period, reduce the frequency of watering to prevent root rot from occurring.
Fertilization
Oxytheca parishii Parry is a low maintenance plant that requires minimal fertilization. You can sprinkle an all-purpose fertilizer, rich in nitrogen, once a year, just before the growing season. However, it is advisable to avoid placing too much fertilizer, as it might encourage fast growth, resulting in spindly growth and floppy stems.
Pruning
Oxytheca parishii Parry requires minimal pruning. However, occasional pruning can help to shape the plant and encourage bushy growth. Prune the plant once a year, during the plant's dormancy period, by gently trimming the tip of the stems, removing no more than a third of the stem's total length. You can also remove all the leaves and stems that have died to give room for new growth.
Propagation of Oxytheca parishii Parry
Oxytheca parishii Parry can be propagated by seeds or cuttings. Here are the details on how to propagate this plant using these two methods:
Propagation by seeds
The seeds of Oxytheca parishii Parry are small and black. To propagate the plant using seeds, you must first obtain fresh seeds from a reliable source. Next, follow the steps below:
- Sow the seeds in a well-draining soil mix. Use a container with drainage holes at the bottom.
- Water the soil gently after sowing the seeds. Avoid overwatering, as this may cause the seeds to rot.
- Place the container in a warm and bright location, but avoid direct sunlight. The optimal temperature range for seed germination is between 68-77°F (20-25°C).
- Keep the soil moist but not soggy by watering whenever the top layer of soil feels dry to the touch.
- The seeds should germinate within 1-2 weeks. Once the seedlings have developed a few true leaves, they can be transplanted to individual pots.
Propagation by cuttings
Propagating Oxytheca parishii Parry from cuttings is a reliable method for producing new plants that are genetically identical to the parent plant. Here are the steps to follow:
- Choose a healthy stem from the parent plant and make a clean cut below a node or leaf joint.
- Remove any leaves from the lower half of the stem to create a bare stem segment.
- Dip the cut end of the stem in rooting hormone powder to promote root development.
- Insert the cutting into a well-draining soil mix and place it in a bright but shaded location.
- Maintain the soil moisture by misting the cutting with water or covering it with a plastic bag to create a humid environment.
- Roots should develop within 3-6 weeks. When you see new growth emerging from the cutting, it is a sign that roots have formed, and the new plant is established.
- Gradually expose the new plant to more light and reduce watering frequency until it can be treated like a mature plant.
By following the above propagation methods, you can easily grow Oxytheca parishii Parry and enjoy its lovely pink flowers and unique foliage.
Disease Management
Oxytheca parishii Parry is susceptible to several diseases, including Fusarium root rot, powdery mildew, and rust.
To manage Fusarium root rot, it is recommended to plant in well-draining soil and avoid overwatering. Fungicides containing thiophanate-methyl or benomyl may be effective in controlling the disease.
To manage powdery mildew, it is important to maintain good air circulation and avoid overhead irrigation. Fungicides containing sulfur, myclobutanil or propiconazole are effective in controlling powdery mildew.
Rust, another disease affecting Oxytheca parishii Parry, can be managed by removing and disposing of infected plant material. Fungicides containing chlorothalonil or azoxystrobin may be effective in controlling the disease.
Pest Management
Oxytheca parishii Parry is relatively pest-free, but may suffer damage from occasional attacks by pests like spider mites and aphids.
Spider mites and aphids can be controlled with insecticidal soaps or neem oil. Biological controls such as predatory mites or ladybugs may also be effective in managing these pests.
