Day 317: Hydrangeas

“With immense flower heads, hydrangeas flaunt an old-fashioned charm that is hard to resist. Colors also beguile with clear blues, vibrant pinks, frosty whites, lavender, and rose—sometimes all blooming on the same plant! The colors of some hydrangeas—especially mophead and lacecap—can change color based on the soil pH, which affects relative availability of aluminum ions. Acidic soils with a pH of less than 5.5 produce blue flowers; soils with a pH greater than 5.5 product pink flowers. White flowers are not affected by pH.” To read more click here

  1. Beautiful! Back in the day when you could still find rusty nails, grandma always put a couple of them in the hole before she planted a pink hydrangea so it would get purple. She didn’t know the science, but she knew it worked. 🙂
