Unique Facts About Seeds

Cardinal Climber is a hybrid vine resulting from a cross involving Ipomoea coccinea and Ipomoea quamoclit.
Its botanical name, Ipomoea × multifida, reflects its hybrid origin.
The vine has finely divided, feathery foliage that gives it a delicate appearance.
Scarlet tubular flowers are particularly attractive to hummingbirds.

Growing Instructions

Planting Season: Sow outdoors after the danger of frost has passed and the soil has warmed. In cooler climates, seeds can be started indoors several weeks before the last expected frost.

Sowing: Sow seeds directly into prepared soil or start them in individual biodegradable pots. Cardinal Climber develops a climbing root system and is best disturbed as little as possible during transplanting.

Depth: Plant seeds approximately one-quarter inch deep and cover lightly with fine soil.

Spacing: Space plants approximately six to twelve inches apart when growing them along a trellis or other support.

Sunlight: Choose a location receiving full sun for vigorous vine growth and abundant flowering.

Soil: Grow in fertile, well-drained soil. Incorporating compost before planting can improve soil structure and provide nutrients.

Watering: Keep the soil consistently moist during germination and early growth. Once established, water when the soil begins to dry, providing additional moisture during prolonged hot or dry weather.

Germination: Germination commonly occurs within approximately seven to twenty-one days under suitable warmth and moisture conditions.

Transplanting: If started indoors, transplant carefully after frost has passed. Harden seedlings gradually before placing them outdoors, and avoid excessive root disturbance.

Fertilizing: Feed with compost or a balanced fertilizer if the soil is poor. Avoid excessive nitrogen, as it may encourage foliage at the expense of flowers.

Care: Provide a sturdy trellis, fence, arch, or other support for the twining vines. Guide young stems toward the support as they develop. Remove weeds around seedlings and provide consistent moisture.

Flowering/Maturity: Plants generally begin flowering during summer and can continue into early autumn when growing conditions remain favorable. The vivid red flowers stand out against the finely divided green foliage.
