Hostas are popular perennials for shady gardens. Hosta ‘Blue Jay’ is a sought-after cultivar. Its distinctive blue coloration and robust growth make it a favorite for adding visual interest and texture.
Distinctive Features of Hosta ‘Blue Jay’
Hosta ‘Blue Jay’ is known for its intense, powder-blue foliage. The leaves are heart-shaped, slightly cupped, and exhibit a thick, corrugated texture, contributing to their unique appearance. The glaucous texture gives the plant its signature blue hue, most vibrant in late spring and early summer.
It forms a dense mound, reaching approximately 18 inches tall, with flower stalks extending up to 28 inches, and spreads about 24 inches wide. In mid-summer, delicate spikes of pale lavender, almost white, tubular flowers emerge above the foliage, adding appeal.
Planting and Cultivation
Proper site selection and soil preparation are key for Hosta ‘Blue Jay’. They thrive in partial to full shade; blue varieties need shadier conditions to maintain their intense blue coloration. Direct, hot afternoon sun can cause the blue pigment to fade, turning leaves green.
It prefers well-draining, humus-rich soil that is consistently moist. An ideal soil pH is slightly acidic to neutral (6.0-7.0). Amend the soil with organic matter like compost or aged manure to improve drainage and nutrient content.
Dig a hole twice the root ball’s width and deep enough for the crown to sit at soil level. Space plants about 20 inches apart to allow for mature spread. Water thoroughly after planting to settle the soil.
Ongoing Care and Maintenance
Consistent moisture is important, especially during the first growing season. After establishment, aim for about an inch of water per week. During hot or dry periods, increase watering to keep soil evenly moist and prevent root rot. Watering at the base of the plant in the morning is beneficial.
Fertilization supports growth and vibrant foliage. In early spring, as new leaves emerge, apply a balanced, slow-release granular fertilizer (e.g., 10-10-10). Avoid fertilizing after mid-summer to prevent tender new growth susceptible to frost damage. Incorporating compost into the soil annually also provides a steady supply of nutrients and enhances soil structure.
Remove yellowed or damaged leaves throughout the growing season to maintain vigor and appearance. Deadheading spent flower stalks is optional but can redirect the plant’s energy towards foliage development. As winter approaches, foliage yellows and dies back. After a hard freeze, cut the plant back to the ground. Apply a thin layer of mulch around the base to insulate roots and protect them during winter dormancy.
Common Issues and Solutions
Slugs and snails can chew holes in leaves. They are most active at night and thrive in moist environments. Manage them with physical barriers like coarse sand, or shallow dishes of beer as traps. Removing leaf debris and maintaining good air circulation also helps reduce their habitat.
The blue color can fade to green with too much direct sunlight. If leaves lose their blue hue, assess exposure and consider relocating to a shadier spot. Browning leaf edges often indicate insufficient watering or sun scorch. Ensure consistent soil moisture and adequate shade. If the plant appears stressed (wilting or stunted growth), review its watering schedule and check for proper soil drainage.
