Warm, orangey yellow flowers with stunning, dark centres. This vibrant mix of black-eyed Susans (Thunbergia alata) brightens up the garden. The plants sprawl and can be placed along supports. The clock vine also looks great as a hanging plant. You can plant the flower seeds all year round. Sow at a temperature of 20 degrees in a seed tray or large flower pot (3 or 4 seeds per pot). The seeds can be planted outdoors from mid-May. The flowers bloom all summer long. The climbing plant grows to about 50 cm tall.
Space the clock vine seeds 20 cm apart. Space the rows at a distance of 20 cm. Plant at a depth of 0.5 to 1 cm. Give the Black-eyed Susan a sunny but sheltered spot. After sowing, water the seeds adequately. The flower seeds come in a bag containing approximately 0.5 grams. This is enough to sow 1 square metre.
