Beneficial plants are species that attract beneficial insects to your garden and farm. Nature has evolved to include checks and balances on conditions in the garden that are not in balance. Plants talk to each other and they talk to the insect world, emitting substances that attract the helpers they need when under stress from attack. The beneficial insects they attract will have a deleterious effect on the infestations of insects that are damaging them. Plants have also evolved to attract insects to pollinate them and many times these insects will pollinate your plants as well. There are many good books out on the subject such as 'Attracting Native Pollinators' by the Xerces Society. Less sprays or barriers are needed to protect your plants when you install plant species that attract beneficial insects. Native plants in your garden provide habitat for native insects which in turn provides food for native birds, a worthy thing to do. The plants you choose to include in your garden are not necessarily just going to look nice, thrive in the conditions in your area and/or provide herb, leaf or fruit for your enjoyment, they also can provide habitat for wildlife. The thoughtful gardener can have a powerful effect on what happens in their environs by choosing plant species wisely. A good book on why every gardener should include some native plants in their yard or farm is 'Bringing Nature Home' by entomologist Douglas Tallamy.

Below are two lists of plants that are grown at Intermountain Nursery that are considered beneficial. The top list contains plants that attract insects that prey on damaging insect species in Central California. The second list is of plants that attract pollinators and the time of year they bloom. Many farms are installing permanent rows of shrubs, perennials & trees called 'hedgerows' using the plants on these lists. Please contact us if you wish more information. Check out our availability list to see if the species listed here are currently available. These lists are still under construction, but rather than wait until they are complete, we have uploaded them now and we will continue to fill out more details as time goes on.  All species listed are beneficial even if the details are not yet noted. 12-02-2014
