There are over forty species of the Yucca plant. Yucca rostrata is often confused with a similar member known as Yucca rigidia, which is a slow-growing, medium-sized tree-like yucca, native to Mexico.
Yucca rostrata also has a cultivar called “Sapphire Skies” that produces creamy-white flowers between mid to late summer. It can grow up to 5′ feet tall and resemble a palm tree. The cultivar likes full sun and dry soils.
Light & Temperature
Big bend yucca needs to grow in full sun for best results. Place it in a well-lit spot in your backyard. As a winter hardy plant, it’s suited to USDA Zones 5 through 11.
Water & Humidity
This yucca needs regular watering – once a week – while it’s growing in summer and spring. Water it as soon as the soil looks dry. However, don’t drown the roots in excess moisture as the plants thrive well in dry soils. As soon as the temperature drops in fall and winter, cut down the watering to once a month.
The plant prefers dry, well-drained soil that is either neutral or alkaline, but if you only have slightly acidic soil, don’t fret. It can handle a wide pH range if necessary.
Fertilizer isn’t necessary. However, if you want to boost plant growth, add a balanced, time-released fertilizer during spring. Water well afterwards.
