Fun Facts About Poinsettia Plants

The genus Euphorbia, to which the Poinsettia Plant belongs is related to 1600 other
species.   The same genus contains Gopher Spurge (E. lathyris) which supposed to repel moles and other critters.  Other relatives are Snow-on-the-mountain (E. marginata) and Crown of Thorns (E. milli). Poinsettia plants are the best selling flowering plant during the holiday season. With so many colors and hundreds of varieties, it is challenging to pick just one favorite.

Selecting and Caring for Your Poinsettia Plants

Fresh poinsettia plants have little or no yellow pollen  showing on the flower clusters in the center of the bracts. Plants that have shed their pollen will soon drop their colorful bracts or leaves. Also, avoid purchasing plants that are wilted and have battered leaves.

To prolong the life of a poinsettia plant, avoid placing it in hot or cold drafts. They are highly sensitive to cold temperatures. Even a few minutes of exposure will cause the leaf and bract to discolor, wilt and drop.

Keep the soil moist, but not soggy. Drying out will cause premature leaf loss. Give them a bright location but no direct sunlight when they are in bloom. Ideal temperatures are 70-75 degrees F during the day and 60-65 degrees F during the night. To grow them beyond the holiday season fertilize them once a month.  Want to learn more?  Go to
