Insectary plant

As such, beneficial insectary plants are intentionally introduced into an ecosystem to increase pollen and nectar resources required by the natural enemies of the harmful or unwanted insects pests.

Fennel, angelica, coriander (cilantro), dill, and wild carrot all provide in great number the tiny flowers required by parasitic wasps.

Low-growing plants, such as thyme, rosemary, or mint, provide shelter for ground beetles and other beneficial insects.

Composite flowers (daisy and chamomile) and mints (spearmint, peppermint, or catnip) will attract predatory wasps, hoverflies, and robber flies.

Other insectary plants include: mustard plants such as Brassica juncea, Phacelia tanacetifolia, buckwheat (Fagopyrum esculentum), marigold (Tagetes patula), elderberry, Korean licorice mint (Agastache rugosa), blackberry, Convolvulus, Crataegus, Anthriscus sylvestris, Chrysanthemum segetum, Scrophularia, Rosa canina, Hedera helix, Centaurea cyanus, Eschscholzia californica, Prunus spinosa, Lobularia maritima.
