Best Hydrangea Varieties For Florida: Heat Tolerant And Hardy Choices

When it comes to selecting hydrangea varieties that can withstand Florida’s heat and humidity, there are a few standout choices. Bigleaf hydrangeas (Hydrangea macrophylla) and mountain hydrangeas (Hydrangea serrata) are two types well-suited for North and Central Florida gardens. These shade-preferring shrubs produce spherical clusters of white, pink, blue, or purple flowers, depending on soil conditions and cultivar.

One notable variety to consider is the Endless Summer® series of hydrangeas. This collection, along with other reflowering hydrangeas, has successfully thrived in the Florida climate. Their ability to bloom continuously throughout the growing season makes them an excellent choice for gardeners in the Sunshine State.

It is worth mentioning that bigleaf and mountain hydrangeas require shade, moist soil, and cooler winters. Once established, these shrubs demonstrate moderate drought tolerance and moderate salt tolerance. Their rounded growth habit and large, leathery leaves add a touch of elegance and beauty to any landscape. While some cultivars can be grown in containers, it is important to choose varieties that are specifically adapted to the unique climate of Florida.

Ideal Placement And Care For Hydrangeas In Florida: Morning Sun, Afternoon Shade

Proper placement is key to ensuring the success of hydrangeas in Florida. Morning sun and afternoon shade are ideal for these plants, as it replicates their natural environment and provides the necessary conditions for healthy growth and prolific blooms.

As previously mentioned, hydrangeas should be placed on the northern or eastern side of the home, where they can receive the gentle morning sun. This allows them to soak up the necessary light without being subjected to the intense heat of the afternoon sun. By providing afternoon shade, perhaps from nearby trees or shrubs, you protect the plants from the scorching rays that can cause leaf damage and wilt.

In addition to proper placement, regular care is essential for hydrangeas in Florida. Adequate watering is crucial, especially during the hot and dry months. The plants should be watered thoroughly to ensure the moisture reaches the roots. This can be achieved by watering at the base of the plant, near the soil, rather than sprinkling the leaves. Mulching around the base of the plant helps retain moisture and prevent rapid drying of the soil.

It is also important to note that pruning is typically unnecessary unless there is dieback or the plants outgrow their preferred size. Hydrangeas naturally flower on both old and new growth, so excessive pruning can remove potential blooms.

Important Watering Tips For Hydrangeas In The Florida Climate

Water is vital for the success of hydrangeas in Florida, as the hot and humid climate quickly dries out the soil. To ensure healthy growth and vibrant blooms, proper watering techniques are crucial.

Consistent and thorough watering is critical, especially during the growing season. Hydrangeas prefer moist soil, so it is important to water them deeply to ensure the moisture reaches the roots. Shallow watering can lead to surface roots, making the plant more vulnerable to drought and heat stress.

To maintain necessary moisture levels and prevent rapid soil drying, consider mulching around the base of the plant. Mulch acts as a protective barrier that keeps the soil cool and retains moisture. This not only reduces the frequency of watering but also creates a more favorable environment for hydrangeas to thrive.

Regularly monitoring the soil moisture levels is essential to avoid overwatering or underwatering. Hydrangeas prefer evenly moist soil, but they can suffer from root rot if the soil becomes waterlogged. To check soil moisture, stick your finger into the soil up to the first knuckle. If it feels dry at that depth, it is time to water. Adjusting the watering frequency based on weather conditions and the specific needs of each plant will help ensure their overall health and vitality.

Hydrangea Types For North And Central Florida: Bigleaf And Mountain Hydrangeas

Florida’s unique climate presents certain challenges for gardening, but with the right selection of plants, it is still possible to create a beautiful and thriving garden. Two hydrangea types that have proven their ability to flourish in the North and Central Florida regions are the bigleaf hydrangea (Hydrangea macrophylla) and the mountain hydrangea (Hydrangea serrata).

Bigleaf and mountain hydrangeas are shade-preferring shrubs that produce clusters of white, pink, blue, or purple flowers, depending on soil conditions and cultivar. These hydrangeas are well adapted to shaded areas and can produce an impressive display of colorful flowers even under limited light conditions. Their ability to thrive in shaded areas makes them suitable for mixed-shrub beds or large massed-beds, adding beauty and charm to any landscape.

It is worth noting that these hydrangeas typically bloom for 5 to 9 weeks in late spring or early summer. Some varieties, however, have been known to flower for much longer, such as those observed at the UF/IFAS North Florida Research and Education Center, where some hydrangeas have flowered for over 30 weeks. This showcases their resiliency and their potential to bring long-lasting beauty to your garden.

When it comes to flower color, bigleaf and mountain hydrangeas offer a range of possibilities. The color of their flowers depends on the amount of flower pigment and aluminum present, which are influenced by soil acidity. More acidic soils produce blue flowers, while less acidic soils result in pink flowers. The addition of aluminum sulfate can enhance the blue color of the flowers. Additionally, purple flowers can occur in soil with a pH of 5.5-6.5 or when a pink cultivar is grown in acid soil.
