We decided to buy these beautiful garden lights taking advantage of the Mother's day promo that most stores seem to have for it: $19.99 for a set of three instead of up to $39.99 regular price. Each set has 3 beautiful plastic lily flowers: red, yellow, and green (we chose to get two sets to put them up on two sides of a pathway). The flowers are solar powered, so you don't need any wires or plugs. During the day, they accumulate solar energy; by the time it gets dark, they are fully charged, so they light up and glow. They light up on their own: automatic sensors tell them when it is dark, so you do not have to turn them on and off, either.
The lily flowers look very lovely alongside the pathway. Even during daytime they draw the eye, serving as beautiful garden decor, and when they start glowing at night - it is magical. I am thinking about buying some for the lawn as well.
