Did you know these poinsettia facts?

Poinsettia ‘Snowcap’

True flowers (yellow) of poinsettia in center of bright floral bracts.

♦ Poinsettias are NOT poisonous. That old myth was dispelled by a research project at The Ohio State University in 1975. While the latex sap may be irritating to the eyes, the plants are not toxic.

♦ All poinsettia flowers are yellow. The showy "flowers" of red, pink or white are actually floral bracts (modified leaves). The true flowers are those pouch-shaped things in the centers of the bracts.

♦ Poinsettias are in the genus Euphorbia. Also in that same genus are plants like crown of thorns and baseball cactus. It’s a huge and varied clan.

You’ll see lots of stories on poinsettias in the next several weeks. Let’s hit just the high spots – the critical care guidelines.

♦ Protect your poinsettia from freezing weather when you buy it or take it home from church. 30 seconds of exposure to below-freezing temperatures will ruin a poinsettia. Have the car warmed up.

♦ Keep your plant cool (70 degrees), bright (near a window) and moist at all times. The single biggest reason poinsettias become unattractive indoors is that we let them get too dry. You don’t want to keep it waterlogged, either, but certainly do not let it wilt.

♦ Your plant will not require fertilizer while it’s inside. It really isn’t attempting to grow, so additional nutrients are unnecessary.

♦ If you intend to keep your plant for the next year, leave it in its current pot until late winter or early spring. Trim it back once the floral bracts have faded. Poinsettias are rank growers, so it will need a larger pot by March, and you’ll probably want to pinch out its growing tips every month or so to keep it compact. By the end of the summer, it should be in a large pot (24 to 30 inches) filled with good potting soil. By October 1, you’ll want to be giving it total darkness for 14 hours each night and bright sunlight for 10 daylight hours. Those extended periods of uninterrupted dark are what triggers the flowering process. All that said, it’s easier to buy new plants each December.
