True or false

Real trees. (Harry Scull Jr. / News file photo)

1.) True. “Evergreens” refers to firs, pines, spruces, hemlocks (and some broad-leaved plants such as boxwoods that keep their leaves). All trees are plants, in case that’s where you went wrong.

2.) False. Fraser firs are most popular, followed by other kinds of firs such as Douglas, Concolor. Decades ago Scots pines and spruces were most popular; 2018 stats aren’t in, however.

3.) True, probably beginning late-15th century; later widely popularized in Victorian England.

4.) False. Real trees grow on farms using sustainable practices, and provide wildlife habitat. They are often the only choice for farmers who might otherwise sell the land to developers. Artificial trees come mostly from China, use petroleum products, and end up in landfills in an average of eight years.

5.) True. Additional claims about aspirin, soda pop, etc. are mostly unproven.

6.) True. The poisoning legend is a complete myth as proven by many universities. Poinsettias are a Euphorbia and are not edible however. (Eating bushels of them would make any mammal throw up.)

7.) True.

8.) False. Poinsettias will die if you leave them standing in their own water so remove the foil cap and dump the dish after watering. They will last longest if you lower the nighttime temperature (60 to 65 degrees) and keep the room no hotter than 70 in the daytime. Avoid drafts.

9.) False. Boxwood trees are made by florists or in garden centers by clipping ends of boxwood branches and sticking them into foam, attempting to make a cone-shaped “tree.”

10.) True. Be careful what you introduce in the house and watch for nibbling.

Short answers

Paperwhites. (

11.) Paperwhites. Other bulbs need a cold treatment.

12.) Norfolk Island Pines. Once a 6-inch plant, mine is now 6 feet, I take it outside in summer, and use it inside as a Christmas tree.

13.) Lenten Rose or Christmas Rose.

14.) Christmas cactus.

15.) Cut back the stem but not the leaves, and grow the leaves through summer.

Quiz results: 15 correct: You are probably a true plant person.
12-14 correct: You’ve been reading and listening. Fewer correct: That’s OK – you’ve been busy. But take time to notice how plants enrich our lives all year long.
