What to Know for Beautiful Blooms Hydrangeas are beloved for their show-stopping blooms, rich textures, and seasonal color changes. But caring for them successfully requires a bit of strategy — especially when it comes to pruning and placement. Here’s a detailed guide to the three main hydrangea types you’ll find in northern Minnesota, how to…
Hydrangea paniculata ‘Rendia’
This variety has abundant, long lasting, rounded flower heads that start white and progress to pink, intense raspberry red and finally wine red. Flowers start blooming in July and take on red coloration earlier in the season than other pink paniculatas. Flower color is best in the fall when night temperatures are 10 degrees cooler than day temperatures. Compared to Strawberry Sundae, Diamond Rouge is slightly bigger and has distinct raspberry-red flowers that color earlier in the season. Benefits from multiple prunes in production to produce strong stems. Flower color varies based on climate and growing conditions.
Hydrangea paniculata ‘Rensun’
Strawberry Sundae is similar to Vanilla Strawberry but much more compact. Flowers emerge creamy white in mid- summer and change to pink as night temperatures cool down. With its compact habit, this hydrangea adds striking flowers to small spaces and is nicely proportioned for patio containers. The color lasts well into fall. Excellent for fresh cut and dried flower arrangements. Flower color varies based on climate and growing conditions.
Hydrangea paniculata ‘HYPMAD I’
With a commanding presence in the summer and fall garden, White Diamonds is an exceptional compact hydrangea with glistening white panicles that are held upright and eventually fade to parchment and pink. Smaller and more manageable than most H. paniculata, White Diamonds boasts dark green leathery foliage that displays increased heat and drought tolerance. Use as an anchor in the mixed border, plant as a hedge or in a large grouping for a magnificent effect.
Hydrangea arborescens ‘BAIful’
FlowerFull Smooth Hydrangea produces significantly bolder blooms, sturdier upright stems, and two-to-three times more blooms per season than other Hydrangea arborescens. It’s proliferation of blooms is held high on strong stems that don’t flop in the wind and rain.
Cold climate gardeners, rejoice: there’s finally a purple hydrangea for you! Introducing Invincibelle Mini Mauvette® hydrangea – it’s unlike anything that’s ever come before. Why? Well, it blooms every single year, even in cold climates and is impervious to bad pruning. It’s the same type of hydrangea as the classic and much-loved ‘Annabelle’ but instead of plain white blooms, the flowers are a deep pink-mauve, and they’re held up on strong, sturdy stems that don’t flop. The show begins in early summer and because Invincibelle Mini Mauvette is a rebloomer, it continues clear through frost for an endless supply of flowers for the landscape or vase (both fresh and dried!).
This long-awaited introduction is a step forward in paniculata breeding. With strong, upright stems and large cone-shaped flower panicles that stay upright, this plant is a summer stunner. Like the other paniculatas from Mr. Renault at Pépinières Renault, the flower color starts out white in July then progresses to dark pink. Coloring occurs from the bottom and progresses to the top of the panicle. Berry White® blooms a little later than Strawberry Sundae® and about the same time as Vanilla Strawberry™. Color shades can vary according to location, climate and type of soil. Our growers like this plant, and we think you will, too.
The enormous flower heads are a blend of vanilla and strawberry, held upright on red stems. Flowers emerge creamy white in midsummer, change to pink as the night temperatures drop and finally turn strawberry red. New blooms emerge as older blooms change color, giving the plant a multicolored effect in late summer and early fall. The red coloring lasts at least 3-4 weeks. Plants grow upright, then cascade later in the season. Excellent for fresh cut and dried flower arrangements. Flower color varies based on climate and growing conditions. Bred by Jean Renault in France.
This new, compact form of the famed Annabelle hydrangea is perfect for smaller spaces. Masses of big, white flower heads put on a spectacular show throughout summer, and the straight sturdy stems hold up even in heavy rain. Ideal for borders or in containers. Superb cut flowers. Deciduous.
