What Kind Of Hydrangeas Grow Well In Colorado?

Hydrangeas are a popular and beautiful flowering plant in Colorado, known for their large and colorful blooms. However, growing hydrangeas in Colorado can be challenging due to the state’s unique climate and conditions. Most parts of Colorado are dry, with hot summers and cold winters. The ideal timeframe for planting hydrangeas in Colorado is during early spring or late summer. Oakleaf and panicle hydrangeas, which have large lobed leaves and tall cone-shaped clusters of flowers, are suitable for the Denver area. Most varieties prefer full sun, but not harsh sun.

Pee Gee, a variety with large, cone-shaped flowers, thrives well in both hot and cold climates. Hydrangeas grow particularly well in North and East-facing exposures, but it is best to avoid Southwest or Western exposures. The cultivar “Annabelle” (white pompom flowers) can do well if sited properly, but many newer introductions have not had good success.

If you’re looking to grow hydrangeas in Colorado, consider trying one of the “ever-blooming” H. macrophylla cultivars, which bloom on both old and new trees. Endless Summer® The Original™, Endless Summer® BloomStruck™, and Endless Summer® Twist-n-Shout™ are some of the best options for growing hydrangeas in Colorado.

What is the most heat tolerant hydrangea?

The Smooth hydrangea, native to the eastern United States, is a heat-tolerant plant with dense growth and attractive grayish green leaves. It can reach heights and widths of about 10 feet and is accustomed to warmer climates. The Bigleaf hydrangea, with its shiny, toothed leaves and symmetrical shape, is another heat-tolerant plant with a mature height of 4 to 8 feet. It is divided into two flower types – lacecap and mophead – and is among the most heat-tolerant hydrangeas.

The Panicle hydrangea, another heat-tolerant plant, needs five to six hours of sunlight and can grow up to 20 feet. It is hardy and heat-tolerant, reaching heights of about 6 feet and turning reddish bronze in autumn. Oakleaf hydrangeas are drought-tolerant but still need moisture during hot, dry weather.

Should I cover hydrangeas for freeze?

Hydrangeas need protection depending on the winter temperature drop. If the air temperature doesn’t drop below 0 degrees (zone 7) there is no need for winter protection. In colder climates, wrap or cover marginally hardy hydrangeas, especially those that bloom on old wood, like mop head/big leaf hydrangeas. Newer varieties bloom on both new and old wood. Hardier hydrangeas like paniculata and arborescens don’t need extra winter protection, but extreme cold can cause die-back of their branches.

If a colder than normal winter is predicted, consider covering plants with burlap or a mulch mountain. There’s still time to plant hydrangeas, as they can grow in Zone 4 and warmer zones (5 to 9) and fall is the best time for planting. Follow the steps above, especially watering and mulching.
