Sub-Tropical regions are found at slightly higher latitude from the more moderate climates in the tropics. Our subtropical rooms largely contain plants from the wetter regions in these places. In fact, we have an entire room dedicated to aquatic plants that is maintained under sub-tropical conditions. The plants in our sub-tropical collection expect a cool winter dormancy, and some will only flower in response to getting enough hours below certain temperatures. Late winter when we warn the rooms containing our sub-tropical collections is when you can expect to see the plants bursting into bloom – a preview of the conditions to come outdoors.
