Skimmia is a member of the rue family (Rutaceae), which also includes citrus trees. The family link is clear from the leaves: if you crush them, they release a citrus fragrance. In the wild Skimmia grows in the forests of China and other parts of Asia such as the Himalayas. However, the version in your garden was created in a Dutch greenhouse. If you want the plant to thrive in your garden, you need to place a male Skimmia alongside a couple of ladies to ensure pollination. The male plant can be identified by its shape: it flowers slightly more vigorously and the flowers have pistils.
