Here's our recommendations for drought tolerant garden plants that can also cope with winter frost and full sun. We've included some plants that gardening books might tell you are more tender, but our customers say perform well in their outback gardens. Test them out in yours! NOTE: While your tubestock plants are young and establishing, for at least the first three months after planting, water regularly to help them form roots and new shoots. New tubestock plants should be protected from frost, until they have developed a woody stem, or are much larger in size.
