Beneficial Insects Love Irises!

Purple Iris, 2006, my Hoopa Garden.

Irises make an important contribution to the garden environment by attracting a variety of predatory ground beetles. The larva of these beetles live in the soil, where they consume slug eggs and slug larva.

The key to putting ground beetle attracting Irises to work for you most effectively, is to plant just a few each of a large variety of Irises that bloom at different times, and spread them around the garden.  The longer you can keep the adult ground beetles happy, the more likely they will be to lay eggs in your soil.  Ground beetles also prefer soil rich in organic matter, with strategically placed sections of rotten limbs or other untreated wood, to use as daytime shelter and nursery areas for egg laying.
