Kadie, this can be a disappointment, but in the one bloom you can see very pure dark coloring in the petals. You may find in the next bloom cycle that it is quite different. Keep in a filtered light situation once bud starts to unfurl.
I find that in photo's from ordering. Sometimes the photo has been taken when the bloom is not completely open and some completely open, as is yours.
I will not post here, but I have two trees that have bloomed quite different from first blooming to the next. Awaiting on the next to see what it throws at me.
