Heartleaf Philodendron.....small, medium and large......

Here are 3 forms of heartleaf philodendron that I found in the research greenhouse yesterday.

1. Small narrow leaves.....unique secondary branching habit.....

2. A little wider leaf but still small compared to normal.....these guys also branch naturally......

3. The big guy (below) has larger leaves and shorter internodes than standard heartleaf....
