The whole plant can be seen here, and another (even more floriferous) plant here.  A plant without flowers, nicely illustrating the formal nature of its foliar habit, can be seen here.

This cultivar is also known as Petrocosmea species G25KC00, reflecting some uncertainty about the accuracy of the P. rosettifolia name.
