Gardener's HQ Yucca Gloriosa Growing Guide

This plant is native to the sandy, coastal regions of the southeastern US, from North Carolina down to Florida. Therefore, It thrives in well-drained, sandy soil, and also does well in rocky soil.

Ideally the Yucca Gloriosa plant enjoys an alkaline soil with a pH of 5.5 to 6.5.

Spanish Sword is drought tolerant so it does need to be watered regularly. Indeed good drainage is important — do not let it stand in water as standing water can cause root-rot.

While Yucca Gloriosa looks similar to the varieties of Yucca native to the desert regions of the Southwest, it will not thrive in a true, desert environment. As it naturally grows at the southeastern coast, it is adapted to areas with milder temperatures and greater rainfall.

This plant doesn’t require any pruning, except to cut away dead leaves, also cut down the flower stalk once it dies.
