Cycas ophiolitica (Cycas Marlborough Blue) is a large shrub native to Australia that can reach 5-10 feet tall when planted in the right conditions. This plant thrives in semi-shade with moderate water and can tolerate an arid climate. The foliage is rather ornamental with fine, soft leaflets that create a beautiful, silvery-blue hue contrasting against the vibrant environment.
If you'd like to add Cycas ophiolitica to your garden, it is best suited to growing in USDA Zones 9-11, but some enthusiasts successfully grow them in colder regions with a bit more care. Generally, a sheltered, partially-shaded spot is ideal with well-draining soil. During cold weather, it is advisable to keep the plant in a pot and bring it indoors. This will help to prevent frost damage to the fronds. Additionally, if the plant is grown in a pot, water it sparingly in the winter and more regularly during the summer months. By doing this and providing it with some protection from extreme temperatures, you can ensure that your Cycas ophiolitica thrives in a cold climate.
