Height/Spread:
Depending on the type. Smaller trees can grow to be 2 to 4 feet tall and wide, while larger trees can grow to be 30 feet tall and 25 feet wide with offsets. Allowing offsets to grow can result in clumps that are several times the size of the individual plant.
Bloom time:
Depending on the type, some will bloom in the spring and others in the mid-to-late summer. Polycarpic perennials are perennials that bloom every year for the rest of their lives. Monocarpic variants, such as Hesperoyucca whipplei (syn. Yucca whipplei), blossom once and then slowly decline and die, much like their close relatives, Agave spp.
Color and characteristics:
Leaves are usually long and narrow, sword-shaped, spine-tipped, and grouped in rosettes; they can be thick or thin. Some plants have razor-sharp foliage. Flowers bloom on huge stalks that arise from the plant’s core, some reaching a height of over 10 feet. Flowers are often white or cream in color, with a tinge of pink, purple, or green in some kinds.
Toxicity:
Animals (and people) are generally scared off by the spiky and thorny nature of some yuccas. They can, however, be moderately poisonous to cats, dogs, and humans if consumed.
Yucca vs. yuca:
Yuccas are not related to yucas (one ‘c’), despite the fact that they are frequently mistaken. Yuca, often known as cassava, is a plant containing edible, starchy tubers/roots that are used to make tapioca and cassava flour. The yucca plant’s roots are not edible.
How fast does a yucca plant grow?
- Fast growth (up to 2 feet each year), eventually reaching a height of 1530 feet and a width of 8 feet, with several trunks.
- In smaller gardens, the striking silhouette is out of scale either used alone or in combination with other large-size foliage plants.
How do you stop yuccas from growing taller?
After the flowers have dried, snip off the spent blooms. 3 to 4 inches above the point where the stalk emerges from the main stem, cut the stalk. The yucca height is controlled by this, as the bloom stalks are several feet tall.
How tall do outdoor yucca plants grow?
Yucca thrives on soil that drains well and can be in full sun, as it is a native of the southern United States. It can even resist temperatures as low as 10 degrees Fahrenheit. (-12 C.), making it possible to grow a yucca plant in a variety of climes.
The creamy-white flowers bloom best in full light from mid-to-late summer, with some yucca reaching heights of up to 10 feet (3 meters) and leaves up to 2 1/2 feet (76 cm).
How long does a yucca tree live?
In fact, the Joshua tree is also known as the yucca palm, and Palmdale, which is home to a plethora of yucca palms, was named after it.
A pollinating moth has a unique and mutually beneficial interaction with Yucca trees.
The yucca pollen grains are transferred to stigmas (female flower parts), where the moth deposits its eggs. Just as yucca seeds begin to develop, larvae of the yucca moth emerge from these eggs. The larvae feed on the seeds, leaving some behind to help another generation of yuccas grow and provide food for future generations of yucca moths.
Yuccas are related to agaves and exist in similar environments, with the exception that yuccas are more cold tolerant than agaves and, unlike agaves, nearly all yucca species do not die after flowering, lasting for more than 100 years when correctly located.
The yucca plant is found across the United States, with some species native to the Midwest and Southeast.
Although native to Central America, the huge yucca is the most popular yucca in Southern California (Yucca elephantipes). It can reach a height of up to 30 feet in a short amount of time.
The leaves of the lanceolate plant are velvety and luscious green. Giant yucca can tolerate almost full light in Ventura and coastal areas, but in our interior valleys, it prefers half-day exposure and will be damaged by harsh afternoon rays.
The Spanish bayonet (Yucca aloifolia) is known for its towering vertical inflorescences, which can reach a height of 2 feet this time of year. Because its leaves are extremely pointed, it should not be planted near entrances or walkways, as its name suggests. It’s a slow-growing shrub that reaches a height of around 10 feet.
The banana yucca (Yucca baccata) generates intriguing fibers as well as tasty 6-inch fruits that are frost resistant. Yucca linearifolia (to 4 feet tall) and Yucca rostrata (to 10 feet tall) are beautiful, slow-growing tiny trees with extremely thin leaves that form enormous bunches on the ends of thatched trunks, giving them the appearance of palm trees from a distance.
All of the yuccas mentioned above are native to the Southwest or Mexico, are drought tolerant, and can thrive in full to half-day sun.
Take 3- to 6-inch stem cuttings topped with leaves this time of year, detach all but the most upper leaves, lay them on their sides in the shade for a few days, and then plant them in fast-draining soil in 6-inch (1 gallon) containers. Within a month, if placed in dappled sunshine and watered enough to keep the soil moist, roots should begin to grow.
If your yucca produces seeds, you’ll need to scarify them by rubbing them on sandpaper before putting them in a cactus soil mix at a depth equivalent to the seeds’ length. Place in partial light with a layer of compost on top. Within two weeks, the seeds should sprout.
“I have a tangerine tree that has produced abundantly since I planted it around 10 years ago,” RoseMarie Walker, who gardens in Granada Hills, wrote in an email.
every year for several months, I provided friends and neighbors. Everything is incredibly delicious and seedless.
“It’s almost barren this year.” Despite the abundance of blossoms, I can immediately count the limited number of tangerines it contains. So, what happened?
“I had it trimmed last fall.” “Could that be the issue, or is it infected?” “Could it be too much rain, or is it infected?”
The fact that you received your regular flower harvest but very little fruit suggests a variety of possibilities. The severe rain, as you say, may have played a role in your meager yield. Certain minerals, such as calcium and boron, that play a role in keeping flowers and fruit attached to their stems, would have leached or flowed through the soil as a result of the rain.
It’s also possible that your tree merely needs a break after ten years of intense fruiting, especially because some tangerine kinds are noted for alternate bearing, which means they produce huge crops every other year.
Also, as you indicate, it’s possible that the rain triggered a fungus infection in your flowers, contaminating them and causing them to fall off before fruit could grow.
It’s a good idea to fertilize your tangerine tree according to the instructions on the bag of specially designed “citrus food” that you can get at any nursery or garden center.
By the way, the word tangerine derives from Tangier, a place on Morocco’s northern edge near the Straits of Gibraltar, straight across from Spain, where an unique mandarin variety that would become known as tangerine was produced.
The first tangerines were exported to the United States from Tangier in 1842, arriving at Palatka, Florida. From there, their popularity skyrocketed.
“Why do I keep reading that hellebores don’t grow here?” wrote Joan Stevens in an email. In Pasadena, I live in zone 10A. I think hellebores are gorgeous, and I’d like to plant some of the brightly colored kinds. Is it worthwhile to try, in your opinion?”
Yes, hellebores thrive in our climate. For many years, I’ve had a clump of cream-colored hellebores growing in a mostly shady position. Flowering in late winter and early spring, with chalice-shaped flowers swaying softly above blue-gray foliage, this is undoubtedly a seasonal delight.
When the temperature warms up, the foliage dries up and vanishes, yet the plant reappears every winter.
Over the last two decades, there has been a lot of hellebore hybridization, and as you mentioned, there are numerous flower colors available, including yellow, red, violet, and blackish purple. Hellebores are virtually nonexistent from the nursery trade in our area, but are widely available through internet merchants.
Plant them among other shade-loving perennials like Japanese anemone, cyclamen, and clivia.
Do yuccas spread?
Yuccas are drought-resistant and low-maintenance plants. The main stalk of the Yucca plant sends out rhizomes, which help the plant to grow. The rhizomes produce new plants, which is why yucca spreads so quickly that it is considered a pest by some. Cutting the rhizomes with baby plants from the main root is one way to propagate yuccas. The same concept applies to dividing yuccas to regulate their development. Because the yucca plant can jam itself with too many clumps packed closely together, it’s vital to thin it out by dividing it as it grows.
What happens if you get poked by a yucca plant?
The dramatic silhouette of the yucca plant in Tucson’s bright desert setting makes it a spectacular addition to any drought-tolerant garden. Residents and gardeners should be cautious, as a new Australian study has discovered that the razor-sharp needles of yucca plants can inflict permanent ear and hearing damage.
Getting to the Point
Plants with strong natural defenses abound in the desert. There are dozens of sharp ways the desert flora says hello, from the sharp spines of organ pipe and saguaro cacti to the spiky thorns of an ocotillo or the small, hooklike needles of a jumping cholla cactus “Please don’t touch me.”
The sharp points and edges of blade-like yucca leaves stand out in this ecosystem for their toughness and the damage they may cause. People who interact with yucca carelessly or mistakenly can receive a rapid and deep puncture wound from the plant’s points. A yucca plant’s spike can often reach bone level and create a small, pinprick-like lesion when removed. Because yucca plants are fibrous and robust, the tip of the yucca blade normally stays attached to the blade and only rarely breaks off in the skin. Yucca punctures, unfortunately, can supply some of the plant’s deadly chemicals, known as “Directing “saponins” into the body can cause a reaction, complicating recuperation and causing damage to red blood cells in the area.
A Real Earful
A yucca injury can occur quickly. When individuals swivel their heads, they frequently miss seeing a sharp blade. Yucca is a popular non-native accent plant in Melbourne, as it is well adapted to the Australian environment. However, the plant’s popularity may be to blame for the high number of yucca-related accidents.
Over the course of five years, 28 patients were hospitalized to Melbourne’s Royal Victorian Eye and Ear Hospital with yucca blade ear injuries. While the pointy tips of yucca cause people to be concerned about keeping the plant out of their eyes, they are less wary about the plant tips near their heads.
Yucca points can cause significant, painful, and possibly irreversible harm. Straight, sharp yucca blades stabbed into the ear canal and perforated the eardrum at the right angle. While punctures to the eardrum (also known as the tympanic membrane) are painful, the perforation can be healed with time and care. Yucca spines, on the other hand, can go deeper than the eardrum. The tiny and delicate bones of the middle ear can be accessed and fractured once a spine has pierced through the tympanic membrane. The ossicles, or fragile bones in the ear, are required for full and proper hearing. Their size and precision, on the other hand, make it extremely difficult for the bones to heal properly if they are broken. Ossicles injuries frequently result in a person’s hearing being permanently impaired.
Even if a yucca puncture does not injure the middle ear, it can leave a mark. Sensitivity and edema in the area around a puncture are frequently caused by saponins in yucca spines. As the body heals, a yucca injury is often sore for a week or longer.
Even the Best-Laid Plants
What should you do to protect yourself from yucca injuries? If you have yucca plants in your garden or landscape, take the time to clip off the spiked points that might harm your eyes and hearing. Spikes that splay out below the level of the forehead should be dulled to assist reduce injury. Cutting off the low tips of the plants helps to keep children and dogs safe.
You might also experiment with less harmful gardening choices. Thornless plants, such as the chuparosa plant’s gorgeous crimson sprays or the Baja fairy duster bush, provide some of the most spectacular hues in the Arizona desert. The yellow bird of paradise shrub is a natural plant with vibrant color and blooms that resemble yucca flowers in their piled structure.
Remember to keep an eye out for our flora and fauna, whether you live in the desert full-time or only visit the dry regions on occasion. Before turning or elevating your head, give spiky plants a wide distance and make sure you’re not in danger.

What happens if you cut the top off a yucca?
Pruning a yucca’s top growing tip effectively stops the plant from expanding and adding height. There will be no new leaves emerging from the plant’s top, and the existing leaves will continue to photosynthesize light but eventually die and fall off. Only if latent buds under the pruning wound emerge and form new upright stem leaders will new leaves appear. When you cut the top off a yucca, you get a stark, unattractive plant that looks like a decapitated body with a sharp architectural outline.
Should yucca plants be cut back?
Pruning a yucca is best done just before it enters its growth stage, as it is with most plants. This will take place in the early spring. Although early spring is the best time to trim a yucca, it can be done at any time. Simply ensure that the yucca plant receives plenty of light while it recovers.
Should yucca plants be cut back in the fall?
Yucca filamentosa (Adam’s needle) is the only yucca that has naturalized as far north as Michigan. It is native to the southeast and eastern sections of the United States, but it has made its way to Michigan. We live in near-desert Central Texas, surrounded by yuccas, and it’s still hard to imagine that a yucca can survive in the snow and cold. Pruning Yucca is rarely necessary, with the exception of removing any dead or broken blades. You must have this plant where you want it since digging out the root will (a) not work because they are HUGE, and (b) cause a slew of tiny little plants (often known as “pups”) to sprout all over the place. If you cut the plant off at the base, the plant will simply ensure its life by putting out more small plants. Cutting it off at the base would be a difficult task that would necessitate the use of a chainsaw and a suit of armor. The only trimming required is of the bloom stalk, which should be cut down as close to the ground as possible when it has finished blooming in late summer to keep the plant clean.
Except for the bloom stalk, don’t try to chop off or dig up anything on your yucca unless you have a lot of space to fill in your garden. You probably didn’t understand that when you were informed that the yucca would come back if you chopped it off at the base, that several would come back at the cut-off base, and then next year when you cut those off at the base… and so on. What are your thoughts on having a yucca forest in your backyard?
Are yucca roots invasive?
Expert landscapers advise against planting yuccas next to the house since they grow tall and their roots are invasive. Keep them away from any buildings. The vast root systems, according to Garden Design, can destabilize foundations, sidewalks, swimming pools, and retaining walls, as well as disturb irrigation pipes. It’s difficult to get rid of the roots once they’ve grown and settled in.
