Tropaeolum comes into bloom from summer to autumn. They carry trumpet shaped flowers, these are a little unusual due to having long spurs. Nasturtium flowers may be orange, red or yellow.
It is best to sow Nasturtium seeds in their final location, whether this be in a container, or in the garden itself. Do this about a week after the last frost.
Nasturtium seeds should be sown at a depth of about 6 mm (1/4 inch) into a slightly acidic soil. The soil should be moist and has good drainage.
Nasturtium likes to grow in an area of the garden that is sunny. Depending on the species annual Tropaeolum should be spaced at 20 cm / 8 inches (small), 35 cm /14 inches (medium sized), or 60 to 90 cm / 2 to 3 feet (large Tropaeolum).

Annual Tropaeolum plant species, such as Nasturtium and Canary creeper, are climbers, so supply a trellis or similar frame that they can grow on. They prefer a moist soil so keep well watered.
