Leaf Description

The leaves of Hydrangea arborescens Candybelle® Marshmallow are dark green, oval, and slightly serrated. The foliage provides a dense backdrop for the large, soft pink flowers, making the blooms stand out even more. The leaves remain attractive throughout the growing season before dropping in late fall.

Flower Description

Bloom Color: Delicate soft blush-pink blooms with a smooth, marshmallow-like tone that fades beautifully with age.

Form: Dense, rounded mophead flowers reaching up to 6–8 inches wide.

Bloom Time: Mid to late summer (typically June to August), depending on climate.

Stem Strength: Exceptionally strong stems that support the large blooms without flopping—a major improvement over older hydrangea varieties.

Pruning & Maintenance

Prune in late winter or early spring before new growth begins. Remove any dead or damaged stems and thin out older wood to encourage new growth. Candybelle® Marshmallow blooms on new wood, so pruning will not impact its flowering ability. Cutting the plant back by one-third will help maintain its shape and encourage more prolific blooming.

Water Needs

Candybelle® Marshmallow requires regular watering, especially during its first growing season. Keep the soil consistently moist, but avoid waterlogging. Water deeply during dry spells to maintain healthy growth and abundant flowering. Established plants are moderately drought-tolerant but will perform best with consistent moisture.

Light Needs

Thrives in full sun to partial shade. For optimal blooming, plant Candybelle® Marshmallow in a location that receives at least 4-6 hours of sunlight per day. In hotter climates, providing some afternoon shade will help protect the plant from intense heat and prevent leaf scorching.

Harvesting

The large, soft pink blooms of Candybelle® Marshmallow are perfect for fresh floral arrangements. Harvest the flowers when they are fully open for the best color and texture. The blooms can also be dried for long-lasting, decorative displays.

Fertilizing

Fertilize in early spring with a balanced, slow-release fertilizer or organic compost to promote healthy growth and prolific blooms. A second light feeding in mid-summer can help sustain the plant through the growing season. Avoid excessive fertilization, as this can lead to lush foliage at the expense of flowers.

Additional Care Tips
  • Mulching: Apply a 2-3 inch layer of mulch around the base to retain moisture, regulate soil temperature, and suppress weeds. Mulching also helps protect the shallow roots from temperature extremes.
  • Pest and Disease Resistance: Candybelle® Marshmallow is generally resistant to pests and diseases. However, monitor for common hydrangea issues such as powdery mildew or aphids, especially in humid conditions. Ensure good air circulation and proper watering to prevent these problems.
  • Winter Care: In colder climates, Candybelle® Marshmallow will drop its leaves and enter dormancy in winter. No special winter care is needed, though mulching the root zone can help protect the plant from extreme cold.
Pollination

Pollination Type: Flowers are primarily sterile florets, but some fertile florets may be present and are insect-pollinated.

Pollinators Attracted: Attracts bees, hoverflies, and occasional butterflies during bloom time.

Pollination Purpose: Though not planted primarily for pollination, it contributes to pollinator health during its flowering period.
