Hosta ‘Kingsize’ is a perennial known for its impressive size and striking appearance. This variety stands out for its immense dimensions, making it a focal point in shaded landscapes. Gardeners value ‘Kingsize’ for its robust presence and lush foliage, which brings a tropical feel to woodland or shade garden settings.
Understanding Hosta Kingsize Characteristics
Hosta ‘Kingsize’ is a substantial plant, reaching a mature height of 3 to 4 feet (36-48 inches) with a spread of about 6 feet (72 inches). Its foliage consists of large, deeply veined leaves that are dark, shiny green. These leaves are thick and corrugated, contributing to the plant’s imposing appearance. In mid to late summer, ‘Kingsize’ produces bell-shaped flowers in shades of pale blue or lavender, attracting hummingbirds. This hosta is a sport of ‘Empress Wu’, sharing its stature but lacking the glaucous coating, which results in its distinctive shiny leaf surface.
Planting and Site Selection
Proper site selection is important for Hosta ‘Kingsize’ to achieve its full size. This hosta thrives in partial to full shade, as direct sunlight can scorch its large leaves. Well-drained, rich soil is ideal; amending the area with organic matter like compost or rotted manure enhances fertility and moisture retention.
When planting, dig a hole twice the width of the root ball and deep enough to accommodate the roots. The crown should be positioned at or slightly below the surrounding soil level. Due to its large spread, ensure adequate spacing of 45-60 cm between plants for proper air circulation and growth. After planting, firm the soil around the roots and water thoroughly to establish the plant.
Care Requirements for Hosta Kingsize
Consistent moisture is important for Hosta ‘Kingsize’, especially during dry periods. Water deeply and regularly, ensuring the soil remains moist but not waterlogged, as hostas do not tolerate sitting in wet soil. Applying a layer of organic mulch, such as compost, shredded bark, or pine needles, helps retain soil moisture, regulate soil temperature, and suppress weeds.
Fertilization is needed once per year in early spring as new growth emerges, using a balanced, slow-release granular fertilizer. Avoid fertilizing after mid-summer to prevent promoting tender new growth vulnerable to early frosts or pests. Hosta ‘Kingsize’ is cold-hardy, thriving in USDA Zones 3 through 9, and requires winter dormancy with temperatures below 40 degrees Fahrenheit.
Managing Common Hosta Challenges
Hosta ‘Kingsize’ can encounter several common issues. Slugs and snails are frequent pests, creating irregular holes in the leaves; removing leaf debris and using bait traps can help control them. Environmental stressors like sun scorch can cause leaves to yellow or brown, particularly with too much direct sun or insufficient moisture. Drought stress also leads to browning leaf tips and wilting.
Diseases such as Hosta Virus X (HVX) can cause mottling, puckering, or stunting of leaves; there is no cure, so remove infected plants to prevent spread. Root rot can occur in overly wet conditions, emphasizing the importance of well-drained soil. Anthracnose, a fungal leaf spot, can appear as irregular spots, especially in warm, wet weather.
