Hosta sieboldiana 'Frances Williams' - Frances Williams Hosta

Frances Williams attracts pollinators such as bees and butterflies with its summer blooms. The dense foliage also provides shelter for small insects and wildlife. Deer and rabbits tend to avoid this hosta due to its thick, textured leaves, making it a great option for gardens prone to browsing by wildlife.

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

• Flowering Season: Mid-summer (June-July)

• Bloom Description: Frances Williams produces tall spikes of pale lavender to white, trumpet-shaped flowers that appear in mid-summer. These delicate blooms rise above the dense foliage and attract bees and butterflies, adding a touch of vertical interest to the plant.

Shade gardens – woodland plantings – large borders – specimen planting for bold foliage – foundation plantings – underplanting of trees

The standout feature of Hosta 'Frances Williams' is its large, heart-shaped blue-green leaves with wide, irregular chartreuse to golden-yellow margins. The leaves are heavily textured and corrugated, providing a bold and distinct appearance. As the plant matures, the foliage becomes more deeply textured, making it an excellent focal point in shaded garden spaces.

– Funnel-shaped blooms held above foliage on tall scapes

– Pale lavender to nearly white in color

– Blooming period: early to midsummer

– Flowers are modest but attractive and can attract bees

• Planting Season: Best planted in early spring or fall when temperatures are cooler, allowing the plant to establish roots before the growing season or winter dormancy.

• Soil Requirements: Prefers rich, well-drained soil that retains moisture but doesn’t become waterlogged. Adding compost or organic matter will improve the soil’s fertility and moisture retention, which is essential for optimal growth.

• Spacing: Space plants 48-60 inches apart to allow for mature spread and to create a dramatic ground-covering effect in mass plantings or borders.

Planting Instructions:

1. Dig a hole twice as wide and as deep as the root ball.
2. Place the plant in the hole with the top of the root ball level with the soil surface.
3. Backfill with soil, tamp gently, and water thoroughly.
4. Apply mulch around the base to retain moisture and suppress weeds.

Pruning is minimal for Hosta 'Frances Williams'. Remove spent flowers after blooming to maintain a neat appearance and redirect energy to the foliage. In late fall or early spring, cut back the dead foliage to the ground to allow new growth to emerge. Regularly remove any damaged or yellowing leaves to keep the plant healthy and tidy.

Frances Williams requires regular watering, especially during its first growing season. Keep the soil consistently moist but avoid overwatering or waterlogged conditions. Established plants are more drought-tolerant but perform best with consistent moisture, particularly during dry spells.

Thrives in partial shade to full shade. For the best foliage color and health, plant Frances Williams in a location that receives morning sun and afternoon shade or dappled sunlight throughout the day. Too much direct sunlight, especially in hot climates, can cause leaf burn and reduce the vibrancy of the chartreuse margins.

While Frances Williams is primarily grown for its foliage, the tall flower spikes can be harvested for use in fresh floral arrangements. The pale lavender to white flowers add a soft, vertical element to indoor displays. Harvest the flowers when they are fully open for the best effect.

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

• Mulching: Apply a 2-3 inch layer of mulch around the base to retain moisture, regulate soil temperature, and reduce weeds. Mulching also helps protect the shallow root system from temperature extremes.

• Pest and Disease Resistance: Frances Williams is generally resistant to pests and diseases. However, slugs and snails may occasionally target the foliage, especially in damp conditions. Use slug deterrents or traps if needed to protect the leaves.

• Winter Care: In colder climates, Frances Williams will die back to the ground in winter. No special winter care is needed; simply cut back the dead foliage in early spring to allow fresh growth to emerge.

Self-pollinating – can produce viable seed from its own pollen

– Can also cross-pollinate with nearby flowering hostas if pollinators are present

– Pollinated primarily by bees and occasionally by wind

– Perfect companion plants:

– Astilbe – complements hosta with plume-like flowers and similar moisture/shade needs

– Ferns (e.g., Dryopteris, Athyrium) – offer fine-textured contrast to bold hosta foliage

– Brunnera macrophylla – pairs well with large-leaf hostas and adds delicate blue spring flowers

– Heuchera – adds vibrant foliage color and blends well in partial shade

– Pulmonaria – early blooms and speckled foliage for multi-season interest

– Tiarella cordifolia – low-growing and great for carpeting around hostas

– Solomon’s Seal (Polygonatum) – graceful arching stems rise behind Frances Williams’ broad leaves
