Not really red as you can see, but still Royal! As this Monarch butterfly will attest to.
A touch of red does appear in the base of the flower tubes, but the lobes are dark pink with a touch of orange in the middle. Interestingly, there are no true reds or blues in the Buddleia genus.
Royal Red Butterfly Bush has a relaxed habit which keeps it from getting quite as tall as some of the other butterfly bushes. The flowers start opening from the bottom of the panicle and gracefully continue up along the stem. Flower stems are often in threes, with the larger flower in the middle.
