Bloom Time: Summer to fall

Plant Size: 2-6 feet

Hardiness Zone: 6-9

These are among the most well-known hydrangea cultivars. Typically coloured in shades of purple, pink, or blue, their huge, spherical flower heads are a striking feature in any landscape. The pH of the soil can be changed to produce a multi-coloured or colour-changing effect, exactly like with other hydrangea varieties.

Bigleaf hydrangeas can have lacecap or mophead heads. According to Kristina Aguilar, associate director of plant information and mapping at Longwood Gardens, “the term mophead is traditionally used for the large, all-sterile florets in round heads.”

6. Tiny Tuff Stuff

The violet-blue lacecap flowers of “Blue Cassel” are quite lovely. These blooms are reblooming and will bloom on both new and old wood.

These shrubs can be planted anywhere in your garden that receives partial shade, either as an understory plant or as a lovely hedge or border. If the soil is very alkaline, this cultivar will exhibit blush tones. The “blue cassel” leaves are a consistent, vivid green throughout the entire season, with little to no fall color variation.

10. Mountain Hydrangea

Bloom Time: Early to late Summer

Plant Size: 3-5 feet

Hardiness Zone: 6-9

Mountain hydrangeas, also known as Hydrangea serrata, are versatile plants that can thrive in various light conditions, including full sun to partial shade. However, they generally prefer partial shade, especially in hotter climates, as too much direct sunlight can scorch their leaves and flowers.

If you’re growing mountain hydrangeas in full sun, it’s essential to provide them with adequate moisture and protection during the hottest part of the day. This can include regular watering, mulching to retain soil moisture, and possibly providing some afternoon shade during peak summer months.

11. Nikko Blue

Bloom Time: Early Summer

Plant Size: 4-6 feet

Hardiness Zone: 6-9

“Nikko Blue” is a cultivar of the Bigleaf Hydrangea (Hydrangea macrophylla). Like many hydrangea varieties, Nikko Blue generally prefers partial shade to filtered sunlight, especially in hotter climates. While it can tolerate some morning sun, it may struggle in full sun, particularly in the afternoon when temperatures are highest.

In areas with cooler climates or where summers are mild, Nikko Blue may tolerate more sun exposure, but it’s still essential to monitor for signs of stress such as wilting or scorched leaves. Providing adequate moisture, mulching, and planting in well-draining soil can help mitigate the effects of full sun.

Overall, while Nikko Blue hydrangeas can handle some sun, it’s generally recommended to plant them in locations with partial shade to ensure optimal growth and health.

12. Rock ‘n Roll

13. Wee Bit Grumpy

The purple petals of “Wee bit grumpy” may be the most vivid on this list. The purpose of the hybridization of this hydrangea is to produce petals with intense color saturation. The shrub is a lovely mounded plant that looks good in most parts of your garden.

It would look particularly lovely, in my opinion, spread over your perennial beds, bringing not only wonderful foliage in the spring, but also rich colour as you wait for the arrival of the purple blossoms.
