Copper Sprinkler Works Flower Sprinklers© water an area up to 15 feet in diameter. The spray nozzle is adjustable for a range of 4 - 15 feet diameter. Each flower sprinkler comes with a step-spike equipped wit a brass swivel for easy hose-hook-up and allows sprinklers to be run in series. With the exception of the Daffodil, all sprays have a round diameter (again, adjustable from 4 - 15 feet in diameter). Daffodil flowers have a fan-shaped spray that comes out from the top of the sprinkler and waters in a horizontal pattern straight out from the sprinkler (vs. in an upward spray diameter).
