Poppies
When grown from seed as an annual, poppies self-sow making them a great option for red flowers in your landscape. The University of Wisconsin-Madison Master Gardener Program notes that poppies can be started inside if necessary, but do need to be kept cooler than room temperature to do well. “They do best sown directly in the desired location in either early spring or late summer/fall to germinate the following spring. Sprinkle the small gray, black or brown seeds on prepared soil, but do not cover. Mixing the seeds with some sand makes it easier to spread them more evenly over the planting area as you can see where you’ve broadcast them.” The seeds should germinate in about a week or two in early spring. Next, check out our favorite yellow flowers for your home landscape.
