In Picture, hosta 'Blue Wedgwood'.Blue colored hostas are a great way to add contrasting colors to your garden bed. Did you ever notice how some blue hostas look blue in spring but by mid-summer look green? Well that is because they are receiving too much sunlight. Blue hostas have a "wax" on their leaves that gives them their great blue coloring. However too much sunlight will burn off that wax coating, causing the hosta to go from blue to green in coloration. I have found that blue hostas can actually take more sun, because they have a natural "sunscreen" built in. That is only good if you don't care if your blue hostas turn green.
