Stunning large flowers with red-brown colour gradients. The sunflower 'Avondzon' (Helianthus annuus) shines like the evening sun in the flower garden. The 'Avondzon' lasts longer than other sunflowers. It is perfect for use as background planting. Sow the flower seeds in late March to mid-April under glass, or outdoors in a seed bed from mid-April to May. Plant the seedlings outdoors after five or six weeks. The flowers bloom from July to October. The plant grows to about 180 cm tall.
Space the sunflower seeds 35 cm apart. Space the rows at a distance of 45 cm. Plant at a depth of 0.5 to 1 cm. The Helianthus grows best in full sun. After sowing, water the seeds adequately. The flower seeds come in a bag containing approximately 4 grams. This is enough to sow 5 square metres.
