Straw flower cactus plants make a beautiful addition to any house. Upon first glance, they appear to be normal cacti with bright, vibrant flowers growing out of the top. However, the flowers are glued to the cacti and not an actual natural part of them. While the flowers are technically dead, they are still capable of opening and closing with moisture and temperature changes, which gives them the appearance of being alive. When properly cared for, a straw flower cactus can last several years.
Provide a pot filled with equal parts peat moss, loam and sand to best replicate the natural conditions of the cactus.
Place the cactus near a window that gets sun throughout most of the day. If you put the plant on a patio or outdoors, make sure it gets partial shade as cacti can burn from too much sun.
Water the soil so it is thoroughly moist. Do not water it again until the soil is completely dried out. Follow this watering regimen for the entire time you have the cactus.
Fertilize the cactus once per month during the spring and summer months. Use a balanced fertilizer, such as a 10-10-10, and dilute it with water to 50 percent . There is no need to fertilize it during the cold months as cacti are dormant during this time.
