Splendens (Nerium oleander ‘Splendens’)

Nerium oleander 'Splendens' is an evergreen oleander cultivar known for fragrant, soft pink double flowers. It is a vigorous shrub for warm climates and can also be grown in a large container where winters are colder.

Nerium oleander 'Splendens' grows best in full sun, ideally with at least 6 hours of direct sunlight daily. More sun generally supports denser growth and heavier flowering.

Water Nerium oleander 'Splendens' regularly while newly planted, then allow the soil to dry somewhat between waterings once it is established. It is drought tolerant, but moderate summer watering usually improves flowering.

Yes, Nerium oleander 'Splendens' is normally evergreen in frost-free or mild-winter climates. Freezing weather can cause leaf drop, shoot damage, or temporary dieback.

Nerium oleander 'Splendens' is generally suited to USDA Zones 8b through 11, with the best outdoor performance in Zones 9 through 11. In colder areas, grow it in a container and protect it from freezes.

Nerium oleander 'Splendens' may tolerate a brief light freeze, but regular freezing damages shoots and can kill exposed growth. Protect container plants before temperatures approach freezing and cover or shelter landscape plants during unusual cold.

Yes, Nerium oleander 'Splendens' tolerates heat, wind, and salt spray, making it useful in many coastal landscapes. Good drainage remains important, especially in areas with heavy rainfall.

Nerium oleander 'Splendens' can mature at roughly 6 to 12 feet tall and 8 to 12 feet wide in suitable conditions. Pruning, container culture, and cold damage can keep it considerably smaller.

Yes, Nerium oleander 'Splendens' grows well in a large container with drainage holes and a fast-draining potting mix. Container plants require more frequent watering in summer and should be moved to a protected location before freezing weather.

Use well-drained sandy or loamy soil for Nerium oleander 'Splendens'. It tolerates relatively poor soil, but waterlogged conditions can damage the roots.

Nerium oleander 'Splendens' usually needs only light feeding when grown in reasonably fertile soil. Apply a balanced fertilizer in spring according to the label, avoiding excessive nitrogen that can encourage foliage at the expense of flowers.

Poor flowering is most often caused by insufficient sunlight, excessive shade, drought stress, cold injury, or overly vigorous nitrogen-fed growth. Also remove basal suckers, which can divert energy from flowering.

Scale insects, mealybugs, and spider mites are among the pests that may affect Nerium oleander 'Splendens'. Inspect leaves and stems regularly and use a labeled treatment appropriate for ornamental shrubs if an infestation develops.

Yellow leaves can result from overwatering, poor drainage, cold stress, drought, or normal aging of older foliage. Check the roots and soil moisture before increasing irrigation or applying fertilizer.

Plant Nerium oleander 'Splendens' in spring after the danger of hard frost has passed, giving the roots a full growing season to establish. In mild climates, fall planting is also possible if the soil drains well.

Space Nerium oleander 'Splendens' about 6 to 12 feet apart for large informal shrubs, adjusting the distance for the desired hedge density. Allow extra room near walkways, buildings, and utility lines because mature plants can become broad.

Propagate Nerium oleander 'Splendens' most reliably from softwood or semi-hardwood cuttings. Root cuttings in a clean, well-drained medium, and wear gloves because the sap is toxic.

Prune Nerium oleander 'Splendens' lightly in late winter or spring, or shape it after flowering. Avoid unnecessary severe pruning because it can reduce flowering and create weak, dense regrowth.

Nerium oleander 'Splendens' can recover from hard pruning, but severe cuts should be reserved for renovation or major cold damage. Make cuts selectively and expect fewer flowers until new growth matures.

Yes, all parts of Nerium oleander 'Splendens' are highly toxic if ingested. Keep it away from children, pets, and livestock, and never use its stems for cooking, skewers, or firewood.

Yes, wear gloves and avoid contact with the sap when pruning or handling Nerium oleander 'Splendens'. Wash your hands and tools afterward, and do not burn the trimmings because the smoke may be toxic.

Nerium oleander 'Splendens' typically produces fragrant soft pink to rosy-pink double flowers, sometimes with white streaking or flecking on the petals. Flower color may deepen as the blooms mature.

Nerium oleander 'Splendens' commonly blooms from late spring through summer and may continue into fall. In warm, frost-free climates, flowering can occur for much of the year.

Yes, the double flowers of Nerium oleander 'Splendens' are generally fragrant. Fragrance and flowering intensity are strongest when the plant receives full sun and adequate moisture during active growth.
