At our September workshop I demonstrated how using seeds that sprout quickly can give you some quick filler plants for your miniature garden. Here are some examples of those seeds that work well. I put them in a large planter and covered them lightly with potting soil. They grew over a three-four week period.Your results will vary depending on the light conditions and the heat applied to the planting tray. Experiment to get the best results. I have had cat grass in my exhibits in the Flower Show and have seen the sprout grow at least an inch a day once they start growing.
