Flowers:

The flowers of Nerium oleander 'Hardy Red' are its most striking feature, showcasing vibrant deep red, trumpet-shaped blooms that appear in clusters at the ends of branches. Each flower measures approximately 1.5–2 inches in diameter, with five delicately overlapping petals and a faintly ruffled edge. Blooming profusely from late spring through fall, the flowers exude a light, sweet fragrance, attracting pollinators such as bees and butterflies. This extended blooming period makes it a standout in the landscape.

Fruit:

After flowering, the plant produces slender, elongated seed pods that are 4–7 inches long. These pods are green when young, turning brown as they mature. Inside, the pods contain silky-haired seeds that are adapted for wind dispersal. While the fruit is not typically ornamental, it adds a natural element to the plant’s appearance. Note: The fruit, like all parts of the plant, is toxic if ingested.

Foliage:

The foliage is evergreen, consisting of long, narrow, lance-shaped leaves that measure 4–8 inches in length and 1–2 inches in width. The leaves are arranged in pairs or whorls of three along the stems. They feature a leathery texture with a dark green, glossy upper surface and a paler underside. The foliage forms a dense canopy, providing a lush, year-round backdrop to the plant’s vibrant flowers. Its resilience to heat and drought makes the foliage stay attractive even in challenging climates.

Planting Instructions:

• Location: Choose a sunny spot with at least 6–8 hours of direct sunlight daily. Partial shade is tolerated but may reduce flowering.
• Soil: Prefers well-draining, sandy, or loamy soil. It tolerates poor soils, including slightly salty and alkaline conditions.
• Spacing: Allow 4–6 feet between plants to accommodate their mature size.

Watering:

• Water deeply during the first growing season to establish a strong root system.
• Once established, it is highly drought-tolerant and only needs occasional watering.
• Avoid overwatering, as soggy soil can lead to root rot.

Fertilization:

• Apply a balanced, slow-release fertilizer (e.g., 10-10-10) in spring and mid-summer to encourage vigorous growth and abundant blooms.
• Avoid over-fertilizing, which can lead to excessive foliage at the expense of flowers.

Pruning:

• Prune in late winter or early spring to shape the plant and encourage new growth.
• Deadhead spent blooms to promote continuous flowering.
• Remove dead or damaged branches as needed.
• Always wear gloves when pruning, as all parts of the plant are toxic.

Temperature and Hardiness:

• Hardy in USDA zones 8–10.
• Can tolerate temperatures down to 15°F but may experience some dieback in colder zones.
• Protect the plant with mulch or cover during unusually harsh winters.

Pests and Diseases:

• Generally pest-resistant, but watch for scale, aphids, or spider mites. Treat infestations with insecticidal soap or neem oil.
• Root rot can occur in poorly drained soils.
• Oleander leaf scorch (caused by Xylella fastidiosa) can be a concern in some regions. Remove infected plants to prevent spread.

Toxicity Warning:

• Highly toxic: All parts of the plant (leaves, flowers, sap) are poisonous if ingested. Keep away from children and pets.
• Exercise caution when handling the plant, and wash hands thoroughly after contact.

Additional Tips:

• Use as a screen or hedge for privacy or as a focal point in drought-tolerant landscapes.
• Encourage airflow around the plant to reduce humidity-related issues.
• Pair with heat-loving companions like Lantana or Agave for a Mediterranean garden vibe.

With proper care, Nerium oleander 'Hardy Red' will reward you with long-lasting, vivid red blooms and an evergreen presence that enhances any landscape.
