General Appearance
The Bush's Poppy Mallow is a perennial plant that grows up to an average height of 6 to 12 inches, with a spreading growth habit of about 1 to 2 feet. It has lobed and hairy leaves that are deep green in color, and can grow up to 4 inches wide. The flowers resemble cup-shaped wine goblets that measure around 2.5 inches across, and come in different shades of pink and purple. The blooms typically last from June to August and can continue up to frost. The fruit that follows the flowering is a schizocarp that breaks into single-seeded forms or small nutlets.
Growth Conditions for Callirhoe papaver (Cav.) Gray var. bushii (Fern.) Waterfall
Light: Callirhoe papaver var. bushii grows best in areas with full sunlight. It requires at least six hours of direct sunlight daily. This plant does not tolerate shade and may grow weak and leggy when grown in partially shaded areas.
Temperature: This plant thrives in warm to hot temperatures, and it is native to the southern United States. It can tolerate a wide range of temperatures, including both high humidity and drought, but it grows best between 60 and 90 degrees Fahrenheit.
Soil: Callirhoe papaver var. bushii grows best in well-drained soil with a neutral pH range of 6.5 to 7.5. Sandy loam soils are preferred, but this plant can do well in a variety of soil types. Soil that retains too much moisture will cause root rot and make the plant susceptible to other pests and diseases.
Water: In terms of water requirements, Callirhoe papaver var. bushii prefers moderate watering. When planted in well-drained soil, it should be watered deeply and infrequently. Overwatering can cause root rot, contributing to the death of the plant. In dry conditions, irrigation is required once a week, or more depending on the climate.
Fertilizer: This plant does not require much fertilizer, and over-fertilizing may harm the plant. After planting, work a small amount of a balanced, slow-release fertilizer into the soil. Fertilizer application, if necessary, must be made early in the plant's growth stage.
Cultivation
The Callirhoe papaver var. bushii is a hardy and adaptable plant that can grow in various soils, including dry or sandy soils, as well as clay soils. The plant prefers full sunlight exposure and can withstand different temperatures, including heat and cold environments. For successful cultivation, consider planting the seeds in early spring or fall and establishing seedlings in well-draining soil to avoid waterlogging.
Watering Needs
Proper watering is a crucial aspect of Callirhoe papaver var. bushii cultivation. You must keep the soil moist but not waterlogged during the first few weeks of planting the seeds or establishing seedlings. However, once the plant is mature, it can withstand dry soil conditions. Therefore, ensure that you water the plant sparingly to prevent overwatering and potential fungal diseases. Furthermore, consider using drip irrigation to control water usage effectively.
Fertilization
The plant does not require heavy fertilization, but you can apply a balanced fertilizer during the growing season. Apply the fertilizer once every two to three months to prevent burning the plant's roots. Always follow the fertilizer package instruction and avoid overapplication of fertilizers.
Pruning
Callirhoe papaver var. bushii does not require routine pruning. However, you can occasionally trim the plant to maintain its compact shape or remove dead or damaged branches and leaves. Additionally, you can prune the plant after the flowering season to promote new growth and better flowering in the next season.
Propagation of Callirhoe Papaver (Cav.) Gray var. Bushii (Fern.) Waterfall
Callirhoe papaver var. bushii can be propagated through several methods, including seeds, stem cuttings, and division.
Seed Propagation
Seeds of Callirhoe papaver var. bushii may be sown in the spring or fall. They require a period of stratification, or cold treatment, before they will germinate. The seeds should be sown directly into the garden bed, as they do not transplant well. The soil should be kept consistently moist until the seedlings emerge.
Stem Cutting Propagation
Stem cuttings of Callirhoe papaver var. bushii may be taken in midsummer. Select a healthy stem and cut a 4-6 inch section with a clean, sharp knife. Remove the lower leaves and place the cutting in a pot filled with well-draining soil. Keep the soil consistently moist and place the pot in a location with bright, indirect sunlight. Once the cutting has developed roots, it can be transplanted into the garden bed.
Division Propagation
Callirhoe papaver var. bushii can also be propagated through division. This method should be done in the early spring. Carefully dig up the plant and separate the root ball into sections, each with several shoots. Replant the sections in well-draining soil and keep the soil consistently moist until the plants have become established.
Disease and Pest Management for Callirhoe papaver var. bushii
Callirhoe papaver var. bushii is a beautiful perennial plant that is quite resistant to most pests and diseases. However, it can sometimes be affected by a few common diseases and pests.
Diseases
Powdery mildew: This is a common fungal disease that affects many plants, including Callirhoe papaver var. bushii. It shows as whitish-grey powder-like patches on the leaves. Powdery mildew thrives in humid conditions, poor air circulation, and when the plants are crowded together. To manage powdery mildew, ensure good air circulation, limit watering the plant from overhead, and remove severely infected leaves.
Root rot: This is a fungal disease that affects the roots of the plant, causing them to decay. It is usually caused by poor soil drainage, overwatering, and poor soil condition. To manage root rot, ensure good drainage and be careful in watering the plants. Avoid overwatering and ensure the soil has good nutrients.
Gray mold: This is a fungal disease that causes wilt and rot of the plant stems and leaves. It affects the plants in humid conditions and when leaves and flowers stay wet for extended periods. To manage gray mold, prune the affected parts of the plant and remove them. Limit watering the plant from overhead, and ensure the plants are spaced correctly for good air circulation.
Pests
Spider mites: These are tiny pests that suck plant sap from the leaves. They are usually found on the undersides of the leaves and spin webs as they move around. To manage spider mites, it's important to keep the plant foliage dry by avoiding overhead watering. You can also treat the affected plant parts with insecticidal soap or neem oil.
Snails and slugs: These are common pests that can feed on the leaves and flowers of the plant. To manage snails and slugs, you can handpick them or use a slug bait.
Aphids: These are small, soft-bodied insects that feed on the plant sap. They usually cluster on the undersides of the leaves, and their feeding can cause leaves to curl or become distorted. To manage aphids, you can spray the plant parts with insecticidal soap or use natural predators like ladybugs.
By implementing good cultural practices, it is possible to prevent most diseases and pest problems. These practices include watering properly, providing good air circulation, proper soil management, and timely removal of affected plant parts.
