Answer: Sounds like you're growing one of the dozens of varieties of Philodendron. The spathe (flower blossom) can grow from 3 inches to 12 inches long, depending upon variety. None of the commonly grown Philodendron's are called 'Swiss Cheese Plant', but your description fits the variety 'augustisectum'. You can propagate your plant by taking the shoots it develops at the base of the plant and rooting them in moist potting soil, or by layering a stem. To layer a stem, simply bend one of the stems down to the soil and anchor it. If you make a small slit and hold it open with a toothpick or small stone, and then anchor the stem so the wound makes contact with the soil, new roots will grow from the wound. Once it has developed a root system, you can cut the new plant from the parent plant, dig it up, and plant it elsewhere in your garden.
