Nerium is perfect for patios, balconies and Mediterranean-style gardens.

What are Nerium plants?

Nerium Oleander is an evergreen flowering shrub native to the Mediterranean region. It is known for its glossy, lance-shaped leaves and clusters of funnel-shaped flowers in white, pink or red.

Oleander is especially popular in warm climates, where it can grow into a large shrub. In cooler regions, it is often grown in pots so it can be moved to a sheltered spot during winter. Depending on the conditions, Nerium can grow between 100 and 300 cm tall.

Oleander White offers crisp, bright blooms, Oleander Pink produces soft pink flowers for a romantic look, and Oleander Red creates a vibrant and eye-catching display.

When to plant Nerium

The best time to plant Nerium is in spring, once the risk of frost has passed. This gives the plant the entire growing season to establish strong roots.

In mild climates, planting in early autumn is also possible. However, in colder regions it is safer to plant in spring to avoid frost damage. When growing Nerium in pots, ensure the container is large enough and has proper drainage.

How to care for Nerium

Nerium is relatively easy to care for, as long as it receives enough warmth and sunlight. In the right conditions, it will bloom abundantly throughout the summer.

Light and location

Nerium thrives in full sun. Choose a bright, warm location where the plant receives at least six to eight hours of direct sunlight daily. The more sun Oleander gets, the more flowers it will produce.

It prefers a sheltered spot protected from strong winds. On terraces and balconies, place the plant against a warm wall for extra heat.

Soil

Oleander prefers well-draining soil. It grows best in fertile soil that does not stay wet for long periods.

When planting in pots, use high-quality potting soil and make sure the container has good drainage holes. Avoid heavy, waterlogged soil, as this can cause root problems.

Watering

During the growing and flowering season, Nerium needs regular watering, especially in hot weather. The soil should stay slightly moist but never soggy.

In pots, water more frequently during summer, as containers dry out faster. In winter, reduce watering significantly, particularly if the plant is kept in a cooler location.

Pruning

Prune Nerium after flowering to maintain its shape and encourage bushier growth. Remove faded flowers and trim back long or untidy stems.

More extensive pruning can be done in early spring before new growth begins. Regular pruning helps keep the plant compact and promotes abundant flowering.

Winter care for Nerium

Nerium is not fully winter hardy in colder climates. It can tolerate light frost for short periods, but prolonged freezing temperatures may damage the plant.

In regions with cold winters, it is best to grow Oleander in pots so it can be moved indoors or to a frost-free greenhouse during winter. Keep the plant in a bright, cool location and water sparingly until spring.

Where to place Nerium in the garden

Nerium is perfect for Mediterranean-style gardens, sunny terraces and patios. It looks stunning as a statement plant in large containers or as part of a warm, drought-tolerant planting scheme.

Oleander combines beautifully with lavender, olive trees, citrus plants and ornamental grasses, creating a relaxed, southern European atmosphere. Its evergreen foliage also provides year-round structure.
