(Spikes) Dracaena indivisa will add a tropical look to your garden border or container. Dracaena or ‘Spike’ as it is commonly known, adds structure and height with its long, slender, sword-shaped leaves. Spikes are very low maintenance. They do best in full sun to part shade, and will reach a height of 2 to 3 feet tall. Dracaena indivisa is a perfect choice as the ‘thriller’ in a mixed container planting, or add vertical interest to a mixed border.
