Pollination Info for White Oleander

White oleander (Nerium oleander) is predominantly pollinated by insects, primarily bees. The plant produces abundant nectar and pollen, serving as an attractive food source for bees.

The flowers of white oleander are funnel-shaped and have five petals. They are typically white in color but may occasionally have a pinkish hue. The flowers contain both male and female reproductive organs and are considered self-fertile. However, cross-pollination can still occur when pollen is transferred from the stamen (male reproductive structure) of one flower to the stigma (female reproductive structure) of another flower.

In addition to bees, white oleander may also be pollinated by other insects such as butterflies, moths, and wasps. The plant relies on pollinators to produce seeds, which are contained within elongated pods that split open when mature.

It is important to note that while white oleander is insect-pollinated, the plant is also toxic to many insects. The flowers and leaves contain a type of toxin called cardiac glycosides, which can have deadly effects on certain animals that consume them. However, bees have evolved to have a certain level of immunity to these toxins, allowing them to safely pollinate white oleander.

Can I propagate my White Oleander plant?

Yes, White Oleander can be propagated using stem cuttings. Take a 4-inch cutting from the tip of a healthy stem, remove the lower leaves, and dip the cut end in rooting hormone. Plant the cutting in a pot filled with well-draining soil and keep it moist until roots develop.

What are some common problems with White Oleander?

• Yellowing leaves: This usually indicates overwatering or nutrient deficiency.
• Black sooty mold: This is caused by an infestation of scale insects. Use insecticidal soap to control the pests.
• Brown spots on leaves: This is a fungal disease called leaf spot. Remove the affected leaves and treat with a fungicide.

Planting & Care Instructions for White Oleander

Planting:

• Choose a sunny location with well-drained soil.
• Dig a hole twice the diameter of the root ball and slightly deeper than the container.
• Remove the plant from the container and gently loosen the roots.
• Place the plant in the hole and backfill with soil, tamping down as you go.
• Water thoroughly after planting.

Care:

• Water regularly, especially during hot, dry weather.
• Fertilize in the early spring and mid-summer with a balanced fertilizer.
• Prune only to shape or control size and only in the late winter or early spring.
• Protect from frost if necessary, as oleanders are sensitive to freezing temperatures.
• Be aware that all parts of the plant are toxic if ingested.

By following these guidelines, you can enjoy the beautiful white flowers of your oleander for years to come.
