Just like McDonald's shamrock shake, Bank of Memories & Flower's shamrock plants are a sign St. Patrick's Day is just around the corner! The three sided clovers of Irish folklore are believed to bring good luck. The care of your indoor shamrock plant is quite basic. Water it at least once every 10-14 days, often enough to keep the soil evenly moist but not too wet. Keep your plant in bright indirect light at a daytime temperature no warmer than 75 degrees and cooler at night about 65 degrees. Fertilize once a month for best results and enjoy!
