Received seed for this plant as a trade. While flowers are stunning and plant is a profuse bloomer, it acts as an annual by setting many seeds before dying back in winter. My experience is that it does come true to seed, but watch out - if you don't collect the seed before they drop, they will sprout the following spring and can be prolific.

Black Dragon is an absolutely gorgeous dark purple to dark burgundy flower, 8-9" in diameter. She doesn't like as much water as most hibiscus, so be more sparing with her.
