Thunderbird features straight, lance shaped leaves covered with burgundy red spots. In full sun, cooler temperatures or drought, the leaf color looks mostly purple. Mangaves are rare intergeneric crosses between Manfreda and Agave which allows them to grow twice as fast as typical Agaves and makes them extremely adaptable to all climates as indoor outdoor plants. Softer leaves than Agaves with no sharp teeth. Great for container gardens. Easy to grow & fun to collect!
