These aptly named cone-bearing seed plants are almost always trees, but there are also a few shrubs in the family. Conifer shrubs can be an excellent addition to landscaping. Many conifers are also “evergreens,” so they stay green year-round. Instead of producing flowers, they produce cones—giving owners plenty of options when it comes to decorating for the holidays. They’re also sturdy and resistant to even the chilliest of winters, including freezing temperatures.
