Proven Winners 2 Gal. Blue Chiffon Rose of Sharon Shrub
Features include suitability for USDA zones 5-9 and a mature size of 48-72 inches wide by 96-144 inches tall. It is a deciduous shrub, meaning foliage will drop in winter with new growth in spring. Best for large spaces or long borders where a wide, soft hedge is desired. This cultivar offers a vibrant blue-toned bloom that can create a cool, calm backdrop in mixed borders. Choose this if you want a standout blue-flowered specimen with substantial height over time; it’s less ideal for very small yards unless paired with a lower-growing species to soften the base. Caution: the large mature size requires ample planting area and stable soil to reach full height and width.
Proven Winners 2 Gal. Purple Pillar Rose of Sharon Shrub
Best for tall, narrow spaces, this cultivar grows to a mature width of about 24-36 inches and a height of 120-192 inches. It thrives in USDA zones 5-9 and handles full sun to partial shade. Best for vertical accents such as island plantings or privacy screens where height is a priority and space is limited. Limitation to consider: its narrow width means it won’t fill wide beds as quickly as broader shrubs, so plan for complementary low-growing plants nearby.
Proven Winners 2 Gal. White Pillar Rose of Sharon Shrub
The White Pillar presents a crisp, light bloom and a similar tall habit to Purple Pillar, reaching 24-36 inches in width and 120-192 inches in height. The plant is suited for USDA zones 5-9 and tolerates full sun to partial shade. It is a strong choice for bright, airy borders, white-focused landscaping schemes, or as a vertical backdrop in perennial beds. Caution: ensure winter protection in colder pockets of zone 5, as extreme cold may impact early spring growth flush.
3 Rose of Sharon Live Plants, Light Pink Flowering Tree
This option arrives as a live plant in a 4-inch container, ready for transplanting. It produces abundant light pink blooms throughout the summer, shaping a tree-form shrub with a naturally rounded crown. Best for focal points, specimen plantings, or a low hedge with seasonal color. Best for gardeners seeking quicker flowering impact from a shorter, container-grown plant. Limitation: as a live plant, it requires careful acclimation and proper planting time to ensure successful establishment in your landscape.
First Editions 2 Gal. French Cabaret Red Rose of Sharon Shrub
French Cabaret Red brings a dramatic red bloom to the garden. It thrives in USDA zones 5-8 and grows to a mature width of 4-7 feet and height of 5-8 feet. As a deciduous shrub, you’ll see foliage loss in winter with new growth emerging in spring. Best for bold color statements in mixed borders or near entryways where a strong seasonal focal point is desired. Consider spacing needs and eventual height when planning companions to avoid crowding or shade on neighboring plants.
Buying Guide
What should I consider before buying a Rose of Sharon?
- Climate suitability: Most cultivars thrive in USDA zones 5-9; verify zone compatibility for your location.
- Sun exposure: Full sun promotes the most prolific blooming; partial shade can reduce flowering intensity.
- Growth habit and space: Pillar forms are best for narrow spaces; larger hedgerow varieties need room to grow.
- Soil and drainage: They prefer well-drained soil; overly wet sites may lead to root issues.
- Maintenance: Deciduous habit means winter foliage loss; plan for seasonal pruning to maintain form and encourage blooms.
And a quick compare-contrast
- Best for bold vertical accents: Purple Pillar and White Pillar, due to their narrow width and tall height.
- Best for wide-border impact: Blue Chiffon and French Cabaret offer strong color and larger spread.
- Best for quick color in a sunny bed: Light Pink live plants provide immediate flowering when established.
How to plant and care for Rose of Sharon
