The yucca most commonly available as an indoor plant in New Zealand is the Yucca Elephantipes. Known variously as the Spineless Yucca, Spanish Dagger, Adam’s Needle, Spanish Bayonet and Soapweed yuccas are hardy perennials. They have thick woody stems that bear, at their upper ends, clusters of long, dark-green, spear-shaped leaves. During late spring and summer, yuccas may produce dramatic clusters of white, bell-shaped flowers. So striking are these flowers that early settlers of the south-western United States called them “Lamparas de Dios” or “Lanterns of God”. Pollination and proper yucca care are necessary for the formation of these flowers on indoor plants.
The Yucca plant – care for this versatile indoor and outdoor plant is flexible, easy care, easy to maintain – and being considered one of the top air cleaning indoor plants is just another benefit.
Yucca thrives in full sunlight, so they're perfect for that west-facing window where everything else burns up. They also do well in bright, indirect sun. Growing yucca in low light will lead to fewer flowers and thinner growth for the plant. Yuccas do not need high quality soil, but it needs to be well-draining. However, it still needs to be heavy enough to hold the plant upright. Yucca plant soil should also retain water well. Try a 3:1 mixture of sand and peat in your container. Yucca is highly sensitive to water-logging. Water regularly in the spring and summer growing season, but make sure the plant has excellent drainage and dries between waterings. Water sporadically in the winter. Never let a yucca plant sit in a tray of water.Fertilize during the growing season with liquid fertilizer or controlled-release fertilizer according to label instructions.
