Yuccas
My favorite plant so far in my garden is my yucca plant. This plant is usually grown in warmer climates (zone 8 and above), but can withstand harsh winters, some frost and even dry spells. Yuccas are perennial plants known by their spiky look and their green color. There are approximately 50 known species of yucca. Some of them bear fruit and flowers (however, mine do not). Yuccas require direct sunlight and are slow growing. Definitely a great ornamental plant to add to your garden.
