Astilbe hybrid 'Ellie' - White Plume False Spirea

Astilbe attracts pollinators such as bees and butterflies due to its nectar-rich flowers. Its dense foliage also provides shelter for small insects, contributing to its ecological value. Additionally, it is deer and rabbit-resistant, making it an excellent choice for gardens prone to wildlife damage.

• Seasonality: Herbaceous perennial; dies back in winter and regrows in spring.

Flowering Season: Mid-summer (June-July)

Shade or woodland borders

Moist garden beds and low-lying areas

Mixed perennial gardens

Light up darker garden areas with white plumes

Great for cut flower use

The foliage of 'Ellie' is fern-like, with finely divided, dark green leaves that provide texture and depth. The foliage stays lush and green throughout the growing season, even when the plant is not in bloom, offering excellent coverage and interest in shaded garden areas.

'Ellie' produces stunning, pure white, plume-like flowers on tall, upright stems. These feathery flower spikes rise above the plant’s dark green foliage, creating a striking display. The flowers bloom in dense clusters and remain for several weeks, making them a standout feature in shaded gardens. These blooms also attract pollinators such as bees and butterflies.

• Planting Season: Plant in early spring or fall when temperatures are cooler, allowing the plant to establish its roots before the growing season or winter.
• Soil Requirements: Prefers rich, well-drained, consistently moist soil. Astilbe thrives in slightly acidic to neutral soil (pH 6.0-7.0). Adding organic matter, such as compost, helps improve moisture retention and soil fertility.
• Spacing: Space plants 18-24 inches apart to allow for air circulation and room for mature spread.

Planting Instructions:

1. Prepare the soil by loosening it and adding organic matter.
2. Dig a hole twice as wide and as deep as the root ball.
3. Place the plant in the hole, ensuring the top of the root ball is level with the soil surface.
4. Backfill with soil, tamp gently, and water thoroughly.
5. Mulch around the base to retain moisture and suppress weeds.

Minimal pruning is required for 'Ellie'. Remove spent flower spikes after blooming to maintain a tidy appearance and encourage healthy growth. In late fall or early winter, cut back the foliage to the ground as the plant enters dormancy. Fresh new growth will emerge in the spring.

Astilbe hybrid 'Ellie' prefers consistently moist soil. Regular watering is essential, especially during dry spells or hot weather. The soil should remain evenly moist but not waterlogged. Mulching helps conserve soil moisture and reduces the need for frequent watering.

Thrives in partial shade to full shade. While 'Ellie' can tolerate some morning sun, it performs best in shaded or lightly filtered light. Full sun exposure can cause the foliage to dry out or scorch, especially in hot climates, so it's best suited for shaded areas.

The flowers of 'Ellie' are ideal for cut flower arrangements. Harvest the flower plumes when they are fully open for maximum vase life. Astilbe blooms can also be dried for long-lasting indoor arrangements—simply cut the flower stalks and hang them upside down in a well-ventilated area to dry.

Fertilize in early spring with a balanced, slow-release fertilizer or compost to support healthy growth and vibrant blooms. A second light feeding after flowering can help sustain the plant through the summer. Avoid over-fertilizing, as it can lead to excessive foliage growth at the expense of flowers.

• Mulching: Apply a 2-3 inch layer of mulch around the plant to retain moisture, reduce weeds, and regulate soil temperature. This is especially important in warmer climates where soil tends to dry out faster.

• Pest and Disease Resistance: Astilbe is generally resistant to pests and diseases but may experience powdery mildew in overly humid conditions. Ensuring good air circulation around the plant helps prevent this issue.

• Winter Care: In colder climates, apply a layer of mulch or compost over the root zone to protect the plant from frost. 'Ellie' will die back in winter but regrow in spring.

Pollination Type:  Self-pollinating

Mechanism:

• Contains both male and female parts in each flower
  
• Insects (bees, flies) help transfer pollen, enhancing seed production but not required for bloom
  

Seed Production:

• While seeds can form, Astilbes are more commonly propagated by division for reliability

Astilbe ‘Ellie’ is a shade-loving, moisture-dependent perennial with elegant white plumes and dark green foliage. It pairs beautifully with plants that either highlight its color or complement its texture.
