Do Joshua trees need to be dormant?
Life History. Joshua trees need to undergo a dormant period of cold weather before flowering, but once they flower, they are dependent upon one tiny insect for pollination. Yucca moths (genus Tegeticula) transfer pollen between flowers to ensure seeds will form, and then they lay their eggs inside the pollinated flower.

Look for sprouts growing up from within the protective branches of a shrub. Young sprouts may grow quickly in the first five years, then slow down considerably thereafter. The tallest Joshua trees in the park loom a whopping forty-plus feet high, a grand presence in the desert. Judging the age of a Joshua tree is challenging: these “trees” do not have growth rings like you would find in an oak or pine. You can make a rough estimate based on height, as Joshua trees grow at rates of one-half inch to three inches per year. Some researchers think an average lifespan for a Joshua tree is about 150 years, but some of our largest trees may be much older than that.

Legend has it that these pioneers named the tree after the biblical figure, Joshua, seeing the limbs of the tree as outstretched in supplication, guiding the travelers westward. However, this tale is not substantiated in the historical record. Some evidence suggests that the biblical figure Joshua, and the Joshua trees, represented the Mormon conquest of the desert.

Joshua Tree (Yucca Brevifolia) Care
A highly cultivated garden environment isn't going to be right for growing a Joshua tree. They thrive in poor soils and where summers are long, hot, and arid, and there's a significant drop in temperatures come winter. Your tree won't survive in a region with high humidity and rainfall.
Types of Joshua Tree
This is not a highly cultivated species, but if you're looking for a compact version of the tree for a smaller landscape, you can opt for Yucca brevifolia var. jaegeriana. This dwarf tree version typically grows to around 10 feet and has shorter branches than the standard Yucca brevifolia .
Pruning
Part of the appeal of the Joshua tree is its distinctive natural form—it won't need any pruning other than to remove any old, damaged flowering stems. By leaving the branches with dry leaves, they can insulate the plant in cold winters by absorbing moisture.
How to Grow Joshua Tree From Seed
Growing Yucca brevifolia from seed is tricky but not impossible. The flowers can only be pollinated by a species of moth native to the trees natural habitat, so hand-pollination using the likes of a small paintbrush is often necessary. For best results, you should sow fully ripe and fresh seeds.
Potting and Repotting
Joshua trees are slow-growing, but they do have an extensive root system. If they are being grown in a container, you should repot them in a larger pot every few years at the end of winter. Because they don't like being transplanted, you need to do this very carefully.
How to Get Yucca Brevifolia to Bloom
When a Joshua tree is in flower in spring, it produces densely clustered panicles that can be up to 20 inches long. The small, individual, white-green flowers are oval-shaped and have an unpleasant, mushroom-like fragrance. Not every tree flowers annually.

The plants also produce offsets, an important bit of Joshua tree information, which can be divided away from the parent plant. Caring for Joshua tree babies is similar to regular yucca care.
How fast do Joshua trees grow?
Joshua trees are fast growers for a desert species; new seedlings may grow at an average rate of 7.6 cm (3.0 in) per year in their first 10 years, then only about 3.8 cm (1.5 in) per year. The trunk consists of thousands of small fibers and lacks annual growth rings, making determining the tree's age difficult. This tree has a top-heavy branch system, but also what has been described as a "deep and extensive" root system, with roots reaching down to 11 m (36 ft). If it survives the rigors of the desert, it can live for hundreds of years; some specimens survive a thousand years. The tallest trees reach about 15 m (49 ft). New plants can grow from seed, but in some populations, new stems grow from underground rhizomes that spread out around the parent tree.
When do Joshua trees bloom?
Flowers typically appear from February to late April, in panicles 30–55 cm tall and 30–38 cm broad, the individual flowers erect, 4–7 cm tall, with six creamy white to green tepals. The tepals are lanceolate and are fused to the middle. The fused pistils are 3 cm tall and the stigma cavity is surrounded by lobes. The semi-fleshy fruit that is produced is green-brown, elliptical, and contains many flat seeds. Joshua trees usually do not branch until after they bloom (though branching may also occur if the growing tip is destroyed by the yucca-boring weevil ), and they do not bloom every year. Like most desert plants, their blooming depends on rainfall at the proper time. They also need a winter freeze before they bloom.

The name "Joshua tree" is commonly said to have been given by a group ...
What is the moth that pollinates the flowers of a Joshua tree?
Once they bloom, the flowers are pollinated by the yucca moth ( Tegeticula synthetica ), which spreads pollen while laying eggs inside the flower. The larvae feed on the seeds, but enough seeds remain to reproduce. The Joshua tree is also able to actively abort ovaries in which too many eggs have been produced.

Where do Joshua trees grow?
Today’s Joshua trees have a fairly restricted range, growing in an archipelago of isolated patches across the Mojave. During the lush Pleistocene, though, the trees grew across far more of the desert. At one point or another over that million-year period, Joshua trees grew near the Colorado River’s delta in present-day Mexico, 300 miles from the southernmost Joshua tree today. They grew in Death Valley at around 200 feet below sea level, perhaps lower. (Imagine sitting near a Joshua tree on the forested shore of Lake Manly, which filled Death Valley hundreds of feet deep.) And at one point or another during the Pleistocene, they likely grew almost everywhere between those two points.

How do yucca moths work?
The females work for a few days, collecting and distributing pollen and laying eggs, and then expire . Within the developing Joshua tree fruit, five distinct seed chambers begin to develop. In one of those chambers, the yucca moth larva hatches from its egg and begins to eat. The seeds, little flat black flakes about the size of a lentil, grow to fill their chambers like stacked coins in a banker’s paper roll. The moth larva eats through one of the five stacks, chews its way out of the fruit and drops to the ground, then burrows into the soil to pupate.

Is high elevation good or bad for trees?
In this fact sheet, the term high elevation will refer to elevations above 5,000 feet. High elevation sites are both good and bad for trees. They have shorter growing seasons because the frost-free period is shorter. Temperatures decrease 5 degrees (F) for every 1,000 foot increase in elevation. Situated at 7,000 feet and higher, Park City can be 20 degrees cooler on average
