Petunia ‘Capella Rim Raspberry’: Compact Elegance with Bold Blooms

Petunia ‘Capella Rim Raspberry’, or Petunia hybrida ‘Capella Rim Raspberry’, commonly known as Capella Rim Raspberry Petunia, is a showy, compact-flowered petunia designed for early color and long-lasting garden performance. Developed by Danziger, this cultivar is part of the Capella series, which is known for its naturally controlled mounding habit, large single blooms, and ability to thrive in both containers and landscape settings.

The defining feature of ‘Capella Rim Raspberry’ is its dramatic color contrast: rich raspberry-purple centers rimmed with clean white edges. These vibrant blooms not only captivate the eye but also attract bees, butterflies, and hummingbirds, making them ideal for pollinator-friendly gardens. Petunia hybrida ‘Capella Rim Raspberry’ belongs to the Solanaceae family, which includes many well-known ornamental and edible plants such as tomatoes and peppers.

Features of Petunia ‘Capella Rim Raspberry’

This petunia was selected for its ability to remain compact during propagation and early production, making it excellent for quarts and small pots. Despite its restrained early growth, it continues to size up in the garden, eventually reaching 8–10 inches (20–25 cm) tall and spreading 10–14 inches (25–36 cm) wide. It’s a reliable performer in both hot summer beds and hanging baskets where strong color is desired with minimal maintenance.

It features a single flower form, with large blossoms that hold their shape well even in variable weather. These traits, combined with its early flowering time, make it a favorite among growers and gardeners alike.

Growing Petunia ‘Capella Rim Raspberry

Light

Capella Rim Raspberry Petunia needs full sun—at least 6 hours per day—to perform its best. Insufficient light will result in leggy growth and reduced flowering. Ideal placement includes sunny garden beds, patios, or window boxes with direct exposure.

Soil

Plant in light, well-drained soil or a high-quality potting mix for containers. Avoid heavy clay or poorly drained sites, as excess moisture at the roots can lead to rot. Soil should be moderately fertile and slightly acidic to neutral in pH (6.0–7.0).

Watering

Water deeply when the top 1–2 inches (2.5–5 cm) of soil feel dry. Capella Rim Raspberry tolerates some dryness but performs best with regular moisture. During hotter weather or in containers, check soil more frequently. Always allow the soil to dry between waterings to avoid soggy roots.

Fertilizing

This petunia benefits from regular feeding. Apply a balanced, water-soluble fertilizer every 1–2 weeks, especially during heavy blooming periods. You can also use a slow-release fertilizer at planting time for low-maintenance care.

Pruning

To keep the plant tidy and blooming, deadhead spent flowers regularly. Trim back any leggy stems to encourage fuller growth. A midseason light pruning can rejuvenate older plants and promote fresh blooming into late summer.

Propagation of Petunia ‘Capella Rim Raspberry’

Capella Rim Raspberry can be propagated by both seed and stem cuttings:

  • By seed: Surface-sow seeds indoors 7–14 days before the last frost date. Seeds require light to germinate and perform best at 70–75°F (21–24°C). Start in a seed tray or plug tray with a moist seed-starting mix, and transplant once seedlings have several true leaves.
  • By cuttings: Softwood stem cuttings can be taken and rooted in a well-draining medium. Bottom heat and humidity will improve success rates.

This variety transplants well once established and roots easily, making it suitable for both amateur and commercial growers.

Uses for Capella Rim Raspberry

  • Hanging baskets and window boxes: Its mounding habit and large blooms cascade gently for a lush display.
  • Container gardens: Ideal for mixed or solo planters, this petunia stays compact and doesn’t outgrow companions.
  • Garden beds and borders: Works beautifully as a low-growing front-of-border plant or color accent along pathways.
  • Mass plantings: Use for a uniform display of raspberry-white blooms that pop from a distance.

Pests and Diseases

Capella petunias are relatively trouble-free but can occasionally suffer from:

  • Aphids, thrips, or whiteflies: Watch for small pests on leaves or buds. Treat with insecticidal soap or neem oil.
  • Powdery mildew: May appear in humid conditions. Improve air circulation and avoid overhead watering.
  • Root rot: Usually a result of poor drainage. Ensure soil dries between waterings and always use well-draining media.

Regular monitoring and early intervention will help prevent these problems.
