Green and colored Valentines hearts

Why should "Valentines day" not go green? I found this heart shaped leaf in the "Kruegerpark" on a bush in South Africa.I should have taken more pictures. I was on a Jeep Safari and "on feet time" was very limited due the big 5 all around. I held it on my hand, so lifted into a layer with Photoshop and gave it a red Valentine glow. Enjoy.
