More about Italian White

Helianthus debilis

Italian White Sunflower is a rustic farmhouse flower with an elegance all its own. Though its name suggests otherwise, the blooms are not pure white, but a soft buttercream with long, delicate petals surrounding a refined, dark brown center. This contrast gives each flower a striking yet understated beauty—more frilled and graceful than the bold golden sunflowers most gardeners know.

Highly branched plants reach about 5–6 feet and are incredibly floriferous, offering an abundance of blooms from mid- to late summer. That branching habit makes them exceptional for cutting, with plenty of stems for bouquets and farmhouse-style arrangements. Each bloom measures about 4–5 inches across, sized perfe... More

That branching habit makes them exceptional for cutting, with plenty of stems for bouquets and farmhouse-style arrangements. Each bloom measures about 4–5 inches across, sized perfectly for casual jars, vases, and rustic displays.

Italian White isn’t about towering giants with single massive heads—it’s about a cloud of buttercream blooms dancing on graceful stems. For gardeners seeking a sunflower that’s softer in tone but generous in flowers, this heirloom delivers charm, abundance, and a timeless touch of farmhouse style.  Blooms 90-100 days after sowing.  Each packet contains a minimum of 50 seeds.

How to Grow Sunflowers

Sunflowers are widely adapted to a variety of climates and are especially tolerant of cold temperatures.  Sunflowers will flourish in a wide variety of soil types, from clay to sandy, so long as sufficient nitrogen is available throughout the growing season.  The water requirements of sunflowers are similar to those of other field crops.  Plants should be irrigated if drought occurs within 20 days of pollination as this period is especially critical for seed development.

After danger of frost has passed, sow seeds 6" apart, 1/2" deep in rows 36" apart.  Germination will occur in 6-10 days.  Thin to one plant every 24" once seedlings have reached six inches tall. Can also be started indoors 4 weeks before the average last frost date.

Transplant outdoors after danger of frost has passed.  Plants should be spaced 18-24" apart to provide for ample air flow.

Sunflowers are susceptible to a number of common diseases including verticillium wilt, mildew, leaf spot, and rust.  However, the extent of these diseases is usually not of consequence to the home gardener.  Ensuring adequate airflow by thinning plants to the recommended spacing will reduce the incidence of disease and cultural practices such as crop rotation, tillage and removal of plant debris in the fall will limit its spread.

Sunflowers make great cut flowers. They are long-lasting and have a bright, cheerful appearance that adds a cheerful touch to any bouquet or arrangement. Sunflowers are also easy to care for, and can last up to a week when cut and placed in a vase with fresh water. When harvesting fresh cut flowers, cut the main head just before it blooms to encourage additional blooms on side shoots. Harvesting flowers in the morning will prevent premature wilting.

CONSIDERATIONS:

Sunflowers are outbreeding plants, relying on bees and other insects for their pollination. Varieties may be self-compatible or self-incompatible, meaning that pollen must be moved from one plant to another. Plants of different varieties must be isolated by 1/2 to 3 miles, depending on the population size and insects in the area, to maintain varietal purity. Hand pollination can be performed by bagging heads and rubbing the flowers of adjacent plants together each day for 10 consecutive days. Heads should be re-bagged after pollination to prevent pollen contamination and predation by birds.

HARVESTING SEED:

SEED LONGETIVITY:

Sunflower seeds can remain viable for up to five years if stored in a cool, dry place.
