The Chamaerops humilis palm is an easy plant to grow indoors. It thrives in bright light and dry air. It will usually top out at four feet when cultivated indoors. As the tree matures, it will start to sprout dangerously sharp spikes all over the trunk. The fronds are very fine and grow into a round shape that has a dozen or more leaflets each. The color ranges from deep green hues to silvery green. The roots of the Chamaerops humilis are very fragile, so once it has reached an ideal size, you can simply dress the soil to keep it healthy.
