I planted a bunch of Rudbeckia seeds this year via Winter Sowing. Let's just say I planted a lot and many different kinds. I have tons of them too ;) I separated all the babies and made a huge flower bed of them all mixed. There is one that has variegated leaves. Some of the leaves have more streaks than others, but it's like white, lighter green and dark green.
Here's the best picture I could get using a flash tonight...
