Pink pearl is a hefty, petal-full, spherical dahlia bloom.
It is in my blush collection with her color almost white but with with light pink tones and sometimes a cream tone to her center though sometimes it is just whitish. A big sister of cameo zoe and diminuitive Irish d porter  in looks, color and how they play together. And she is more prolific than either of those even though she is bigger.
These round ball are a solid 4" across if not even 4.5". Bigger than any true ball dahlias I grow (there are many formal decrativie that act and are close to the true ball form). They are decnt producers of both blooms and tubers. 
Medium to shorter plants but make long stems. Pinch plants early.
Great for wedding work or market boquetes in the blush color pallet (highly popular color with my customers) where she would be your focal flower. 
My only complint, once she starts getting tired the stems get too weak for the full big flower heads. In fall, I always have to remind myself how many stems I picked off of my poor tired dahlia plants when they stop preforming immaculately. They are allow to get tired when stem upon stem was produced.
