|
Flower Description
|
- Color: Pale lavender to white, bell-shaped flowers
- Bloom Time: Blooms typically emerge in midsummer, adding vertical interest and a delicate touch to the plant’s bold foliage.
- Height of Flowers: The flower spikes rise above the foliage, typically reaching 12 to 18 inches.
|
Planting Instructions
|
- Best Time to Plant: Early spring or early fall, allowing the plant to establish itself before the heat of summer or the frost of winter.
Planting Instructions: - Soil Requirements: Prefers well-drained, loamy soil that is rich in organic matter. Amend with compost if necessary to ensure moisture retention.
- Spacing: Plant 18 to 24 inches apart to allow room for the foliage to spread.
- Depth: Plant at the same depth it was in the container, making sure the crown of the plant is level with the soil surface.
|
Pruning & Maintenance
|
- Pruning Needs: Remove yellowing or damaged leaves as needed throughout the growing season to keep the plant looking fresh. Deadhead spent flowers to prevent energy from being used on seed production.
- Winter Care: Mulch in colder climates to protect roots from frost. Leaves will die back naturally with the first frost, and foliage can be cut back once it dies down.
|
Water Needs
|
- Watering Frequency: Keep the soil consistently moist, especially in the first growing season to establish a strong root system.
- Drought Tolerance: While Hosta hybrids are somewhat drought-tolerant, they perform best with regular watering, especially during dry spells.
|
Light Needs
|
- Preferred Light: Partial to full shade.
- Tolerates: Some morning sun but prefers to avoid the harsh afternoon sun, which can scorch the leaves.
|
Harvesting
|
– Hosta ‘Red Cadet’ is not typically harvested as an edible or cut flower plant
– Gardeners may collect dry seed pods in fall for propagation
– For ornamental use, foliage can be trimmed as needed for tidy appearance, or removed after the first frost |
Fertilizing
|
Apply a balanced slow-release fertilizer in early spring as new growth emerges. Reapply midseason if needed, but do not over-fertilize as it can cause overly lush growth that is more prone to disease. |
Additional Care Tips
|
- Mulching: Apply 2-3 inches of mulch around the plant to retain moisture, regulate soil temperature, and suppress weeds.
- Dividing: Divide clumps every 3-5 years in early spring or fall to prevent overcrowding and promote vigorous growth.
- Pests: Generally pest-free, though slugs and snails can occasionally damage the foliage.
|
Pollination
|
Hosta hybrid 'Red Cadet' flowers are typically self-fertile, but they are also attractive to bees and other pollinators, which can enhance the chances of seed formation. |
Companion Plants
|
– Astilbe – adds feathery blooms and thrives in similar moist, shaded conditions
– Heuchera (Coral Bells) – offers colorful foliage and similar size contrast
– Ferns (e.g., Dryopteris, Athyrium) – pair well in woodland or shaded settings
– Brunnera macrophylla – heart-shaped leaves and spring blooms
– Pulmonaria – early-season flowers and speckled foliage complement hosta texture
– Tiarella – forms neat mounds with delicate flower spikes
– Tricyrtis – fall-blooming and moisture-loving, pairs well in understory beds |
