Last year I discovered a method of growing plants from seed called winter sowing. You take an empty gallon milk jug (or any clear, plastic container) and make mini greenhouses out of them. Cut holes in the bottom for drainage, slice the jug open about 3/4 of the way around, leaving one side as a hinge, fill with about 4 to 6 inches of potting mix (not soil) and sow the seeds as it says on the package. Close the container using duct tape to hold the top to the bottom, remove the cap for ventilation and to allow moisture to enter, and mark the container so you know what you planted. Take the container outside in a sheltered area, preferably somewhere where the sun doesn't shine on it all day, and wait for them to sprout when it gets warm. When they are big enough to handle, plant them in your garden. You can grow tons of plants this way for a whole lot less than buying full size plants. I have 16 containers outside right now of hardy perennial seeds, and the annuals will get started in about a month.
Daylilies are my thing too. Last year I bought about 130 different named cultivars and plan to cross a few. Also, when they begin to crowd each other out, I'll thin the clumps and sell the fans, making a little of my jingle back that I spent on the plants. Now what I need is a greenhouse, but that'll just have to be a dream for a while.
