Tiny Mint Leaves

A houseguest in very early March asked if we could prepare a new recipe with mint, so I bought a plant.  The recipe didn't happen, and over the next few weeks the plant developed some kind of fungus.  I tried to save some cuttings, but that didn't work.  I have not yet returned the pot to the garage, and this week I've been watching these little tiny leaves react to the morning sunlight.
