These distinctive conifers are commonly seen in Florida gardens, but some are hardy enough to grow outdoors farther north. Most species bear stiff, closely overlapping, dark to bright green leaves. They accept a wide range of soils with adequate drainage. They thrive in contain- ers for several years.
These trees grow into striking specimens that take up a lot of space. As they age they bear spiny cones that can weigh up to 15 pounds. If one falls on your head from the top of the tree, you'll wander aimlessly for yearsshould you survive the initial impact.

- Make sure they receive bright light, either natural or artificial; they do well near a south- or west-facing window.
