I planted some ‘petite yellow’ marigolds in a window planter in my office on March 22nd. They had germinated along with some volunteer ‘peach melba’ nasturtiums by April 1st. Three marigold plants and two nasturtium plants grew in the planter. I moved some of the plants so that they are evenly spaced.
Here you can see the first marigold flower with a background of nasturtium leaves.
The nasturtiums have already produced several flowers.
