America's favorite seed-starting system and our bestselling product of all time! Even if you've never gardened before, you can be successful with this temperature-controlled system consisting of a bottom watering tray, a clear humidity dome with adjustable ventilation holes, a Styrofoam planting tray with 60 drilled holes, and 120 planting plugs called "bio sponges," complete with pre-drilled holes. Refill bio sponges are readily available here at Park and very reasonably priced. All you do is drop one seed into each sponge, fill the base of the tray with water and fertilizer, and wait for those green sprouts! At transplant time, simply pop out the sponge and plant the whole thing into the ground or pot.

This perennial ornamental grass will astonish you. It quickly forms a rounded, cushion-shaped plant that looks elegant enough for formal settings, with long, slender, strappy dark green foliage. Then in late summer, pink plumes shoot up from all over the plant, filling the fall garden with brilliant color. Sometimes the blooms go right into winter, even as they fade to a bronzy tan. Wildlife love the seeds in the plumes, and you will enjoy cutting the stems for fresh or dried arrangements. Very easy in full sun! Zones 5-10. Pkt is 15 seeds.
