Flowers:
In early to late spring, 'Clyo Red' produces clusters of 5 to 9 fragrant, funnel-shaped flowers, each measuring 1 to 2 inches in length. The blooms are a striking red color, with pistils and stamens that extend elegantly beyond the petals. These blossoms often appear before or as the new leaves emerge, adding a vivid splash of color to the spring landscape. ​

Foliage:
The leaves are obovate to elliptic, measuring 1.5 to 4 inches in length and 0.75 to 1.25 inches in width. They are firm and thick, with a dark green upper surface and a velvety, gray-pubescent underside. In the fall, the foliage transitions to a rusty red hue, providing additional seasonal interest. ​

Fruit:
Following the flowering period, 'Clyo Red' develops woody, elongated capsules approximately 0.5 inches long. These capsules mature in late summer to early fall and split open to release numerous small seeds, contributing to the plant's propagation.

​Rhododendron canescens 'Clyo Red', commonly known as the Piedmont Azalea 'Clyo Red', is a deciduous shrub renowned for its vibrant red blooms and adaptability to various garden settings. To ensure its healthy growth and abundant flowering, consider the following care guidelines:​

Planting Location:
Select a site that offers partial shade, such as morning sun followed by afternoon shade, to protect the plant from intense midday heat. Filtered shade is ideal, especially in warmer regions, to prevent leaf scorch. ​

Soil Requirements:
Plant in moist, well-drained, acidic soils rich in organic matter. A soil pH between 4.5 and 5.5 is ideal. Amending the soil with organic materials like pine bark, shredded leaves, or compost can enhance fertility and structure. Ensure the planting area has good drainage to prevent root rot, as azaleas are sensitive to waterlogged conditions. ​

Watering:
Maintain consistent soil moisture, especially during dry periods, to support the shallow root system. Avoid overwatering, as azaleas do not tolerate soggy soils. Mulching with organic materials helps conserve moisture and regulate soil temperature. ​

Fertilization:
Apply a fertilizer formulated for acid-loving plants in early spring, following the manufacturer's recommendations for application rates. Avoid over-fertilizing, as azaleas are sensitive to excessive nutrients. A soil test can provide specific guidance on nutrient needs.

Pruning:
Minimal pruning is required. If necessary, prune immediately after flowering to maintain shape and remove any dead or damaged branches. Avoid heavy pruning, as it can stress the plant. ​

Pest and Disease Management:
Monitor for common pests such as lace bugs, mites, and scale. Diseases like root rot and powdery mildew can occur, especially in poorly drained soils. Implement good cultural practices, such as proper spacing for air circulation and avoiding overhead watering, to minimize issues.
