    I purchased this plant in late summer during an extended heatwave. It was scraggly and nearly leafless with no flowers, but I had researched this cultivar and took a chance on this xeric, hardy desert plant. The bright orange desert globemallow is a common sight in New Mexico, but this was described as having larger flowers than the orange ones that grow wild, and "watermelon" colored. I put it into a new rock garden in October and didn't expect to see flowers until spring. It snowed and froze at the end of October. A week later after warm temperatures, it produced two lovely watermelon-hued blossoms. I'm looking forward to a full blooming cycle in the spring.
