Catching the sun

Spent most of the day in the garden planting into pots some of the bulbs that arrived a few days ago.  Hope I don't need to bring them indoors again as I've nowhere to put them.  Learned a new tip today - use apple cider vinegar diluted 1lb ACV to 10 gallons  water and pour around azaleas and rhododendrons to feed them.  Hope it works. My azaleas are looking a bit tired. 
The plant caught my eye when I came into the room as the sun shone on the leaves and cast shadows on the wall.
