Pollination Info for Rhododendron catawbiense 'Boursault'

Boursault Rhododendron (Rhododendron catawbiense 'Boursault') is a deciduous shrub that produces gorgeous blooms during the spring. The plant is known for its beautiful, showy flowers that have a strong, sweet fragrance, making them a popular choice for home gardens.

In order for the Boursault Rhododendron to produce blooms, it needs to be pollinated. Pollination is the process by which pollen from the male parts of the plant (stamen) is transferred to the female parts (pistil), resulting in the production of seeds.

Most Rhododendron species are pollinated by bees, butterflies, and other insects. Boursault Rhododendron flowers are especially attractive to bumblebees and honeybees, which are the main pollinators. The bright, showy flowers with a strong fragrance and sweet nectar attract these insects to the plant.

It is important to note that the Boursault Rhododendron is a cross-pollinating plant. This means that the plant requires pollen from another Rhododendron plant to produce fruit and seeds. To ensure proper pollination, it is recommended to plant multiple Rhododendron plants near each other. This helps to increase the chances of cross-pollination and fruit production.

If there are no other Rhododendron plants nearby, it is still possible to pollinate the Boursault Rhododendron manually. This can be done by using a small paintbrush or cotton swab to transfer pollen from the stamen to the pistil. This process should be done early in the morning or late in the day when the flowers are most receptive to pollen.

In conclusion, Boursault Rhododendron requires cross-pollination to produce fruit and seeds. The main pollinators are bumblebees and honeybees. Planting multiple Rhododendron plants near each other increases the chances of cross-pollination, but manual pollination can also be done if necessary.
