Growing Zones 5-9
Penny Mac Hydrangea (Hydrangea macrophylla 'Penny Mac') is a deciduous, ornamental shrub with outstanding blooms! Your Penny Mac is a Bigleaf variety of Hydrangea and you'll be astounded by the large, mophead clusters of delicate florets that adorn your Penny Mac Hydrangea from summer through fall. Each bundle of exquisite blossoms reaches a majestic 7 inches in diameter and will re-bloom repeatedly, blanketing the 8-inch long, dark green foliage in brilliant color.
As the weeks pass, you'll see that the blooms tend to age with a reddish tint for some additional fall color. Penny Mac's foliage transitions to shades of burgundy and purple for a lovely autumn display. Growing 6-8 feet in height and only 3-4 feet in width, these are fantastic upright-growing shrubs that are space-saving, yet put on a significant amount of height!
As with other Hydrangeas, blooms will tend to be bluer in acid soils and pink in alkaline soils. However, whatever the color, your Penny Mac Hydrangea is sure to dress your landscape in exquisite color from summer to fall, as well as draw butterflies and hummingbirds to your yard! Hardy throughout USDA zones 5 through 9 and are very long-lasting blooming ornamentals. The mopheads dry to a lovely tan hue and persist well into winter!
Planting and Application:
Penny Mac Hydrangea has an upright, arching form, lending elegance to the huge heads of flowers atop the stems. These low-maintenance shrubs are perfect for your home's foundations or as an anchor to soften the corners of structures. Tall enough to add narrow hedges and screening around your property, providing flowering definition and privacy without sacrificing space!
Plant one beside your front door for a welcome that guests won't soon forget, or use several as an eye-popping hedge along your driveway. This is an amazing shrub with a lot of options for showcasing its remarkable features. Limb up and expose the multi-stem trunks for a unique specimen tree-form or allow to keep the branches to the ground for hiding an eyesore anywhere!
- Big Mophead Blossoms in Pink or Blue
- Deep Rich Green Quilted Foliage
- Reblooming Bigleaf Hydrangea
- Easy Care Purple/Burgundy Fall Color
- Great for Hedges, Specimen, Foundation & Cut Flowers
#ProPlantTips for Care:
Penny Mac Hydrangea is a vigorous grower, so you won't have to wait long for it to establish itself in your yard. Bigleaf Hydrangea buds are set on new wood so this is especially a great Hydrangea if you live in a colder climate. Plant these Hydrangeas in moderately moist and well-drained soil that is in full sun to partial shade. Preferring morning sun and afternoon shade, especially for those in hotter climates. Mulch the root system well and prune Bigleaf Hydrangea after flowering. Most will bloom earlier on last year's wood so don't cut them back in fall or spring - but wait to see if any pruning needs to be done to remove any dead branch tips as they begin to grow in spring. As the plants age, it is best to remove a few of the oldest fattest canes out to the ground leaving in some younger stems for best bloom. Old blooms can be removed in fall or spring.
- Full Sun & Partial Shade
- Moist To Average Moisture & Mulch
- Almost Any Well-Drained Soil
- Color of Bloom is pH-Dependent
- Prune After Flowering & Early Spring
