Canary Creeper - Tropaeolum Peregrinum
This is a pretty climber with lots of yellow flowers in summer, which soon covers fences if given some string to cling to.
Sow in spring 6mm deep in good compost. Make sure that the compost is moist but not wet and seal in a polythene bag until after germination which usually takes 10-15 days at 13-18C. They can also be sown 6mm deep where they are to flower in late spring. Transplant when large enough to handle into 8cm pots, and grow on in cooler conditions. Gradually acclimatise to outdoor conditions for 1-15 days before planting out after all risk of frost, 23cm apart in a sunny spot on light well drained soil.
