Geranium thunbergii 'Jester's Jacket' comes from a sowing G. thunbergii, a species native to Japan with small white flowers and leaves marked brown. This highest form of 20 cm is often confused with G. yoshinoi 'Confetti' but it is probably from the same plant. The foliage of this geranium is remarkable, green splashed with cream and pink. In summer, small pale pink flowers appear on long trailing stems. In our garden, it grows geranium bordering massive part shade along with the delicate cyparissias Euphorbia 'Fens Ruby'.
I couldn't tell which plant you decided it was.
