Plant and Insect Identification
Identifying a mystery plant on the Internet is tricky, especially if you don't know the botanical terms used to describe plant anatomy. Here are a few tips:
- Flowers, seed pod/fruits/cones, leaf shape and leaf attachment are all important details for accurate identification.
- Try using one of the online keys linked below. Typically online keys focus on plants of a specific region or type, such as weeds or trees.
- Mail or bring in a sample to the Hyde Herbarium in Seattle or email a close up and a growth habit photo to firstname.lastname@example.org.
- Images are not always identified correctly online--check the resource to see if it is reputable. An incorrectly identified image can be misleading.
- Use a hand lens or some type of magnification when identifying a plant to see further details of the plant.
- List all the characteristics of the plant, even traits throughout the year, because it helps in the identification process by focusing on details.
- Use books when keying a plant. The Botanical Garden Vols. 1 & 2 is a good alternative to a traditional key for visual people.
- Preserve samples of plants for identification, put them in a bag in a refrigerator (for a short time) or try pressing the plant piece flat between some newspaper in a phone book. The only issue with this is fruit/berries may cause a mold problem.
- Not in Seattle? Try local Master Gardener Programs for identification help.
