Bigleaf hydrangeas are widely planted and wildly loved by gardeners because of their lush floral displays in shades of lavender, pink, and blue. They have a wide-spreading form and loads of thick stems that can grow up to 6 feet tall. Their large, deep green, broad-oval leaves are stunning as well.
The flowers of the bigleaf hydrangea (Hydrangea macrophylla) can change colors depending on the pH of the soil in which they are planted. The flower color of all bigleaf hydrangea plants is affected by the degree of acidity or alkalinity in the soil. Pink- or red-flowered kinds tend to develop purple or blue flowers when grown in acid or neutral mixtures, and the ones that are normally blue turn pink or a reddish-purple color in alkaline potting soil.
In the summertime, gardeners tend to become pretty love-struck over the hundreds of varieties of the bigleaf hydrangeas available to them. There are more than 400 known cultivars between two species: lacecaps and Hortensia.
Lacecap hydrangeas: This hydrangea produces flowers that resemble flat caps with frilly edges. The flower is a round disk of smaller flowers, edged with larger flowers that are quite showy.
Hortensia hydrangeas: This is a low-growing shrub and the most common form of hydrangeas that are grown in pots. Each of the plants has a short, woody stem and several branches with opposite pairs of pointed oval leaves that are quite shiny. The leaves have stalks that are about an inch long and the main stem and branches can each terminate with a round flower head that can be up to about 7–8 inches wide, made up of many four-petaled flowers from 1–2 inches wide. Sometimes you may find smaller specimens available that have only the unbranched main stem topped by a single flower head. The flowers have greenish buds that will open up to be blue, pink, red, or purple.
When: Plant bigleaf hydrangeas in the spring or the fall.
Where: They are hardy in USDA zones 5 through 9 and will do best in sun to partial shade depending on your location. You can grow bigleaf hydrangeas in shady areas all across the United States, but too much shade often results in really pretty leaves but no flowers. If you have high shade in your yard that is created by deciduous trees or evergreen, you might find that it's the perfect place to plant these flowers (if you live in the East, Northwest, or Midwest part of the country). If you live in California, just about any shady area will work for you if it is not too dense. In the northern part of the country, they require no shade at all. They prefer moist, well-drained soil, but if they're grown in highly alkaline soils they can develop yellow leaves, which is a symptom of chlorosis.
How: Start by digging a hole as deep as the root ball, but two to three times as wide. Set your plant in the hole, and fill it about half full with soil and water thoroughly. When the water has completely drained, fill the remainder of the hole with soil and water again. Space hydrangeas from 3 to 10 feet apart, depending on your location.
If you have access to healthy cuttings, bigleaf hydrangeas are easy to grow using this method because of their readiness to root. Here's how it's done:
This section is filled with information on some of our favorite varieties of hydrangeas.
Nikko Blue (hortensia): This plant grows to be about 6 feet tall with large clusters of blue or lavender flowers. The flowers bloom on old wood. Pruning is required just after the flowers die out in order to maintain the size and shape of the plant and to remove weak, damaged, or old branches and leaves.
Variegata tricolor (lacecap): The gorgeous green leaves of this fast-growing plant are edged with a creamy white color. The flowers are blue or lavender, and this deciduous plant is an excellent choice for a shrub border. It will grow from 4–6 feet tall and wide.
Alpen Glow (hortensia): Words alone cannot describe the beauty of the red, snowball-shaped clusters that are the crowning glory of this exquisite plant. A deciduous shrub, it produces mophead clusters of flowers in the summer that can grow as large as a cantaloupe. The glossy, green leaves only add to the beauty of its extraordinary blooms. If soil pH is highly acidic, the coral-red flowers will become more purplish.

We used to have a hedge of hydrangeas in front of our home in Wisconsin many years ago. Now I have a beautiful pot of them in our Houston backyard. They are so lovely and loaded with blossoms. Thanks for the tips on propagating them.
