Althea Red Pillar

Red Pillar Rose of Sharon

Althea Red Pillar, or Hibiscus Syriacus ‘Red Pillar’, is a unique columnar variety of hibiscus that boasts brilliant red flowers and a narrow, upright growth habit. This hardy shrub can reach heights of 8-10 feet, making it an excellent choice for privacy screens, hedges, or as a tall focal point in the garden. Its striking red blooms, which appear from mid-summer through fall, create a dramatic visual contrast against the dark green, glossy foliage. The upright growth makes it ideal for tight spaces or areas where a more compact form is desired, while still providing an impressive floral display.

Althea Red Pillar thrives in full sun and is highly adaptable to a variety of soil types. It is relatively low-maintenance, requiring minimal pruning and care. Once established, it is also drought-tolerant, making it a perfect choice for gardeners looking for a colorful, easy-care plant that will provide long-lasting beauty throughout the growing season.

Care Instructions:

Planting:
Plant Althea Red Pillar in a sunny location where it will receive at least 6 hours of direct sunlight each day. Choose well-draining soil to avoid root rot. Dig a hole twice the size of the root ball, place the plant at the same depth as it was in the container, and space plants 3-4 feet apart to allow for air circulation.

Watering:
Water regularly during the first year to help establish a strong root system. Once established, Althea Red Pillar is drought-tolerant but benefits from occasional watering during dry spells. Ensure the soil is moist but not waterlogged.

Pruning:
Prune in late winter or early spring before new growth begins. Remove dead or damaged branches, and trim back older stems to encourage healthy new growth. A light prune after flowering can also help maintain the plant’s shape and size.

Pest Control:
Althea Red Pillar is relatively pest-resistant, but it may occasionally attract aphids, spider mites, or whiteflies. Regularly inspect the plant, especially the undersides of the leaves. Use organic insecticidal soap or neem oil if pests are detected.

Soil Tips:
Althea Red Pillar prefers slightly acidic to neutral soil that drains well. Incorporating organic matter or compost before planting will help improve soil structure and promote healthy growth. Avoid heavy, waterlogged soils to prevent root rot.
