Description

Horizon Scarlet Pelargonium stands as a premium F1 hybrid geranium celebrated for its bold, uniform scarlet-red flower clusters and consistent garden performance. This popular Horizon series variety produces large, rounded umbels packed with dozens of vivid scarlet single blooms, each petal holding a saturated crimson tone that does not wash out under strong full sun. Thick, semi-gloss dark green foliage forms full, bushy mounds that offer striking color contrast against the fiery red flower heads from late spring all the way through autumn. Unlike older geranium strains, this hybrid maintains neat growth without scraggly leggy stems even under intense summer heat.
This scarlet pelargonium is a staple for bright, sunny residential landscapes and commercial container displays alike. It shines in window boxes, patio planters, front yard flower beds, and edging along walkways, pairing beautifully with white lobelia and yellow marigolds for eye-catching color combinations. Its abundant blooms attract bees and small butterflies, adding gentle pollinator activity to sunny spaces. With continuous flowering through hot summer months, it delivers long-lasting vibrant color with far less upkeep than many seasonal flowering alternatives.

Planting Season: Start indoor sowing 8–10 weeks before the last spring frost; transplant outdoors once frost risk fully passes
Light Requirement: Full sun (6+ hours direct sunlight daily); minimal shade acceptable but reduces bloom volume
Soil Requirements: Light, fast-draining potting or garden soil with neutral pH; mix perlite to improve drainage
Seed Prep: No cold stratification required; soak seeds in room-temperature water for 12 hours to speed sprouting
Planting Depth: Cover seeds lightly with 1/8 inch (3 mm) fine growing medium
Water Needs: Keep soil evenly moist during germination; allow top layer to dry between waterings once mature
Seedling Spacing: Space transplants 10–14 inches (25–36 cm) apart to support full bushy growth
USDA Hardiness Zones: 9–11 perennial; grown as annual in zones 2–8
Additional Tips: Regular deadheading of spent umbels encourages constant new flower production; avoid overwatering to prevent root rot
