10 Yucca Brevifolia seeds~Joshua tree  

Joshua trees are fast growers for the desert The trunk of a Joshua tree is made of thousands of small fibers and lacks annual growth rings, making it difficult to determine the tree's age. This tree has a top-heavy branch system, If it survives the rigors of the desert it can live for hundreds of years with some specimens surviving up to a thousand years. The tallest trees reach about 15 m tall. New plants can grow from seed, but in some populations, new stems grow from underground rhizomes that spread out around the Joshua tree.

The leaves are dark green, linear shaped,  they are borne in a dense spiral arrangement at the apex of the stems. The leaf margins are white

The flowers are produced in spring from February to late April, in panicles  with six creamy white to green tepals. The tepals are lanceolate and are fused to the middle.  The fruit that is produced is green-brown, elliptical, and contains many seeds.  Like most desert plants, their blooming is dependent on rainfall at the proper time. They also need a winter freeze before they will bloom.
