Stellar Ruby Magnolia

Stellar Ruby Magnolia brings a rich splash of color to the magnolia family. This evergreen variety is known for its narrow, upright habit and striking magenta flowers that bloom in spring, offering a dramatic contrast against its glossy green foliage. This tree grows 12 feet in height and 6 feet in width, making it ideal for smaller spaces, screens, or focal points, this magnolia stays neat and manageable without sacrificing visual impact. 

• Evergreen tree
• Moderate growth rate
• Vibrant magenta flowers with a citrus scent
• Evergreen foliage for year-round beauty
• Blooms in late spring for a seasonal pop

Plant in full sun with well-drained soil, and Stellar Ruby will reward you with continuous charm and color. It’s a true Southern gem that thrives in heat and humidity, but with proper placement and care, it can also adapt to sheltered spots in slightly cooler zones. Best suited for USDA zones 7 through 9.

Stellar Ruby Magnolia is low-maintenance and adds bold color and structure to Texas landscapes with minimal effort. Here’s what it needs:

• Watering: Water deeply during the first growing season to establish a healthy, resilient root system. Once mature, Stellar Ruby Magnolia prefers evenly moist, well-drained soil. Supplemental watering during heat waves, drought, or reflective urban sites helps maintain lush foliage and abundant blooms. Avoid waterlogged soil, which can stress the roots.
• Pruning: Pruning is minimal. Remove dead, damaged, or crossing branches in late winter or early spring to maintain a tidy shape. Light shaping after flowering can enhance structure, but heavy pruning may reduce the number of blooms the following season.
• Fertilizing: Apply a slow-release, balanced fertilizer in early spring to encourage vigorous growth and vibrant flowers. In nutrient-poor soils, a second light feeding in early summer can support foliage density and continued bloom. Avoid excessive nitrogen, which may lead to leafy growth at the expense of flowers.
• Mulching: Spread a 2-3 inch layer of mulch around the base to retain moisture, moderate root temperatures, and suppress weeds. Keep mulch a few inches away from the trunk to prevent rot and improve airflow. Refresh annually for optimal health.
• Winter Care: Stellar Ruby Magnolia is hardy and evergreen. In colder regions, apply a light mulch layer to protect roots from freeze-thaw cycles. Avoid late-season fertilization that could stimulate tender growth vulnerable to frost.

Stellar Ruby Magnolia is as durable as it is beautiful, but can still be susceptible to the following most common issues:

• Leaf Spot: Small brown or black spots may appear during wet, humid conditions. Remove affected leaves and increase airflow to reduce recurrence.
• Scale Insects: Small, waxy bumps along stems or leaf undersides can cause yellowing or leaf drop. Treat with horticultural oil during the growing season.
• Aphids: Clusters on new growth can produce sticky residue. Rinse with water or use insecticidal soap to manage infestations.
• Chlorosis: Yellowing leaves with green veins indicate nutrient deficiencies, often iron. Apply chelated iron and adjust soil pH if necessary.
• Bud Drop: Sudden temperature changes or inconsistent watering can cause flowers to drop prematurely. Maintain steady moisture and avoid pruning during periods of stress.
