Product Description
The Microsun F1 Hybrid Sunflower (Extra Dwarf) is one of the most compact and charming sunflowers available, growing to only 30 cm tall. Despite its small stature, this variety produces bold golden-yellow blooms with classic dark centres, making it a standout choice for pots, patios, balconies, and decorative garden borders. Its pollen-free habit ensures clean, allergy-friendly flowers that are perfect for cutting and indoor displays.
Microsun is a quick performer, flowering in as little as 50 days after a summer sowing, or around 60 days in cooler winter conditions. This rapid growth makes it a favourite for beginner gardeners, children’s projects, or anyone looking for fast results. Each plant produces a striking primary bloom, followed by numerous secondary flowers on branching stems for a continuous display throughout the season.
Short, robust, and reliable, Microsun F1 is also popular for commercial pot production thanks to its uniform habit and early flowering. Whether you’re filling patio containers, edging garden borders, or creating cheerful gift pots, Microsun is a versatile variety that delivers maximum colour in minimal space.

Growing Tips
Sow seeds directly into pots, containers, or the garden, as sunflowers dislike transplanting. Microsun is naturally compact but will produce more secondary blooms if planted in larger containers or open garden soil. Provide a sunny position and water deeply but infrequently to encourage strong taproot growth. A light liquid feed every two weeks will support healthy plants and abundant flowering.
Harvest & Display
Microsun’s golden, pollen-free blooms are perfect for clean indoor vases or brightening outdoor spaces. Its extra dwarf size makes it a standout for patios, balconies, and novelty border displays. Fast to flower, easy to grow, and incredibly rewarding, Microsun is the ultimate choice for gardeners who want big impact in a small package.
