With their large, long-blooming flowers and wide, deep green leaves, hydrangeas are a garden favorite – especially when full sun is not available. Hydrangea mophead blooms, which range from deep indigo blue to light pink, brighten up partly shady spots among ferns and hostas.
The Pee Gee and similar types are also great for sunny spots and have blooms that start late spring as white or green and fade to a wide variety of pinks, bright reds and burgundy colors over the mid to late summer.
All types hold their flower heads through the winter as they fade and can even be cut and saved as dry flowers, sometimes lasting several years as dried flower arrangements. Hydrangea shrubs can be large or compact with large "Mop Head," Lacey or Conical blooms.
Current Availability (Apr. 29)
Hydrangeas perform best in partial sun and with regular applications of an acid fertilizer which
can affect the color of their blooms. For more growing tips, see below.
Mophead Hydrangeas have large composite flowers that can cover the shrub. Color ranges from pink to purple blue. See below for more info.
Lace Cap Hydrangeas have an antique look with more delicate appearing flowers than their Mop Headed cousins.
Hydrangea paniculata 'Grandiflora' sports large conical, ivory flowers. Sometimes referred to as Tree Hydrangea because they can be trained to have a single trunk
Hydrangea Care and Color
Hydrangeas are acid loving shrubs and so do well here in the Pacific Northwest where our abundance of conifer trees lower the pH of our soils. The lower the pH, the higher the acidity and the bluer hydrangea flowers become.
Some hydrangea flowers will become pinker as their soil changes. If blue is more desired than adding an amendment like GrowMore Hydrangea Blueing Formula or an amendment like EB Stone's Rhody and Azalea Food will help the blue return.
