Hydrangeas are beloved for their showy blooms and lush foliage, adding a touch of elegance to any garden. But can these beautiful shrubs thrive in the challenging climate of Colorado? The good news is, yes, you absolutely can grow hydrangeas in Colorado! However, it’s essential to understand the unique considerations this environment presents and choose the right varieties for success.
Factors Affecting Hydrangea Growth in Colorado
Colorado’s high altitude, intense sunlight, dry air, and fluctuating temperatures can pose challenges for hydrangeas, which generally prefer more moderate conditions. Here’s a closer look at how each factor comes into play:
- Intense Sunlight: While hydrangeas generally prefer some shade, the intense Colorado sun can scorch their leaves. Opt for varieties that tolerate more sun or plant them in areas with morning sun and afternoon shade.
- Dry Air and Low Humidity: Colorado’s arid climate can quickly dehydrate hydrangeas. Regular and deep watering, especially during dry spells, is crucial.
- Fluctuating Temperatures: Colorado’s weather can be unpredictable, with sudden late frosts and early warm spells. Choosing cold-hardy hydrangea varieties and providing winter protection is key.
- Soil Conditions: Colorado soils tend to be alkaline, while hydrangeas thrive in slightly acidic soil. Amending the soil with organic matter and ensuring proper drainage is essential.
Choosing the Right Hydrangea Varieties for Colorado
Not all hydrangea varieties are created equal when it comes to Colorado gardens. Some, like the popular ‘Endless Summer’ series, are known for their adaptability to a range of conditions, including those found in Colorado. Other excellent choices include:
- Panicle Hydrangeas (Hydrangea paniculata): These hardy hydrangeas are well-suited to Colorado’s climate, tolerating full sun and colder temperatures. Popular panicle varieties include ‘Limelight,’ ‘Vanilla Strawberry,’ and ‘Bobo.’
- Smooth Hydrangeas (Hydrangea arborescens): These native hydrangeas are highly adaptable and cold-hardy. Look for cultivars like ‘Annabelle,’ ‘Invincibelle Spirit,’ and ‘Incrediball.’
- Mountain Hydrangeas (Hydrangea serrata): As their name suggests, these hydrangeas are naturally adapted to mountainous regions. They prefer partial shade and offer delicate lacecap blooms.

Tips for Growing Hydrangeas in Colorado
- Planting Time: Spring is the ideal time to plant hydrangeas in Colorado, allowing them to establish themselves before winter.
- Soil Preparation: Amend the soil with plenty of organic matter, such as compost or peat moss, to improve drainage and acidity.
- Watering: Water deeply and regularly, especially during dry periods. A layer of mulch around the base of the plant will help retain moisture.
- Fertilizing: Feed hydrangeas in spring with a balanced, slow-release fertilizer. Avoid fertilizing after mid-summer, as this can encourage new growth that is susceptible to frost damage.
- Pruning: Prune panicle and smooth hydrangeas in late winter or early spring, while mountain hydrangeas typically don’t require extensive pruning.
- Winter Protection: Protect hydrangeas from harsh winter conditions by mulching around the base and covering them with burlap or a frost blanket.
Common Questions About Growing Hydrangeas in Colorado
Q: Can I change the color of my hydrangeas in Colorado?
A: Yes, but only certain varieties. Bigleaf hydrangeas (Hydrangea macrophylla) can have their bloom color influenced by the soil pH. In Colorado’s alkaline soils, these hydrangeas will typically bloom pink. To achieve blue blooms, you’ll need to significantly lower your soil pH.
Q: My hydrangea’s leaves are wilting, even though I water regularly. What’s wrong?
A: Wilting leaves can indicate overwatering or underwatering. Check the soil moisture a few inches below the surface. Colorado’s dry air can also contribute to wilting, so ensure you are providing enough water.
