Red Ti and Pride of India are both cordylines. They make good orchid companion plants with the same water, drainage and light requirements. They are somewhat salt sensitive and tend to tip burn (similar to oncidinae) if allowed to dry out. They appreciate a good flush/wash with rain water to minimize salt buildup. These varieties have been grown without heat but under a solid cover through the winter and temperatures down to high 20's. As they grow larger, they do better in large deeper containers that prevent them from tipping and give their large roots room to grow.
