Sum And Substance Hosta
Hosta x 'Sum and Substance'Hosta ‘Sum and Substance’ (Hosta hybrid) is a breathtaking perennial revered for its impressive size and bold chartreuse foliage. Known as one of the largest hosta cultivars, this plant forms a giant mound of slightly corrugated, heart-shaped leaves that can reach up to 2 feet in length. The golden-green foliage intensifies in color with more sun exposure, creating a radiant effect in the garden. In mid to late summer, tall scapes emerge from the center of the mound, showcasing pale lavender flowers that attract pollinators like bees and hummingbirds, adding delicate charm to its striking presence.
Growing to a height of 2–3 feet and spreading up to 5–6 feet wide, ‘Sum and Substance’ is ideal for filling large spaces in shaded gardens. Hardy in USDA zones 3–9, it thrives in part shade to full shade and prefers moist, well-drained, organically rich soil. While tolerant of various soil types and sunlight levels, this hosta performs best in filtered shade with consistent moisture. Its adaptability makes it suitable for woodland gardens, borders, or as a standalone specimen in expansive landscapes.
Hosta ‘Sum and Substance’ is low-maintenance and easy to care for, making it perfect for gardeners seeking an impactful yet fuss-free plant. Regular watering during its establishment phase ensures healthy growth and strong roots. Mulching around the base helps retain soil moisture, suppress weeds, and protect roots during colder months. Fertilizing in early spring with a balanced, slow-release formula promotes vibrant foliage and vigorous growth. Minimal pruning is needed; simply remove spent flowers and discolored leaves to keep the plant looking fresh. Dividing the clump every few years in early spring or late summer helps maintain its vigor and prevents overcrowding.
