Picking Winning Plants

Feeling stumped about what to put in your garden?  Do you like what you see at nurseries but feel uncertain that the plants will do well in your yard?  Many local garden centers and online nurseries have professional horticulturists on staff who will gladly answer your questions.  However, be wary of “impulse buys.”  Garden centers often feature the plants that are blooming that week because they sell well.  A plant might look great in the nursery, but it may not be a winner in your garden.

A few tools will help you make educated decisions.  Know your site’s growing conditions.  Come armed with knowledge from plant reference books, reputable internet sites, or local public gardens or universities.  Your local land-grant university works with the horticulture Cooperative Extension Service for your area (http://www.nasulgc.org/About_Nasulgc/members_land_grant.htm).  They may also have plant databases, ongoing plant trials, new plant introductions, or recommendations.

Image of A plant awards list can also be one of the best tools to narrow the field of choices.  These awards are given to plants with proven performance in different regions.  Awards help set the standard for plant breeders and give the public a quick reference for superior performers.  The U.S. National Arboretum has introduced several award winners of its own (discover our Gold Medal plants at http://www.usna.usda.gov/Newintro/awards.html).

Awards and recommendations may be based on trials, popularity polls, horticultural society competitions, conventions of professional organizations, and the experience of amateur growers.  Plant trials are usually completed by botanic gardens, professional plant growers, universities, or other horticultural institutions.  Plants are rated on various features, such as ornamental value or disease resistance.Image of 'black pearl'

Choosing plants from the following award lists can add to your gardening success.  So, next time you’re stumped, think about adding some tried and tested award winning plants to your garden.  Happy planting!
