Pollination Info for Summer Wine Ninebark (Physocarpus opulifolius 'Seward')

Summer Wine Ninebark (Physocarpus opulifolius 'Seward') is a deciduous shrub that produces clusters of small, white or pink flowers in late spring or early summer. The flowers are hermaphroditic, meaning that each flower contains both male and female reproductive parts.

The flowers of Summer Wine Ninebark are primarily pollinated by insects such as bees, butterflies, and moths. These insects are attracted to the nectar and pollen produced by the flowers and inadvertently transfer pollen from one flower to another as they move from plant to plant.

The fruit of Summer Wine Ninebark is a small, dry capsule containing several seeds. These seeds are dispersed by the wind and the plant can also propagate through root suckers.

It is important to note that Summer Wine Ninebark is self-fertile, meaning that it can produce fruit and seeds without requiring cross-pollination from another plant. However, cross-pollination with other plants of the same species can increase genetic diversity and improve overall plant health.
