Gardeners' Notes:

This is one of the most beautiful and striking trunking Yuccas there is, no question. They look very exotic when mature and trimmed to show the trunk, they definitely have the closest look to the tropical Yucca gigantea out of any other Yucca. Yucca aloifolia grows beautifully here in Salt Lake City, Utah (zone 7b) and has pretty much no issue whatsoever. It definitely never gets too cold for them here, and they just absolutely love the scorching 90-100 F+ summers we have. I recommend this yucca (if you can find it) 100%, you pretty much couldnt find a better looking Yucca than Yucca aloifolia besides a very select few. If you live in Utah or anywhere on the west coast and live in zone 7a+ give one a try, you will NOT be disappointed. They love full blazing sun and are extremely drought, ... read more

Very good plant for dissuading prowlers or unwanted traffic. Very sharp spiked and will draw blood. You can root these from cuttings by simply stripping the lower part of the plant and soaking in water for 5-10 days. (approx.)
I recommend gloves and caution.

Nice Plant untill you Throw a Box into it and the Leaves them self go thure the box. I can see why they would call it a Spanish Dagger or Spanish Bayonet.

I planted a 15-gal Y. aloifolia in mid-September, and the leaves have been turning dark/black on me. Any idea what causes this darkening of the leaves? Several lower leaves turned black and died, and many upper leaves are now showing early stages of the same affliction.

Nip the ends of the leaves 1/4 inch with shears or nippers. I know of no detrimental effects as these leaves eventually become the skirt. You can brush against the plant with your bare arm.

A nice architectural plant capable of surviving the wet, cold winters here in the UK. It has a lovely habit similar to that of Yucca elephantipes (guatamalensis), and grows a multi trunk habit similar.

Like has been re-itterated though this plant is lethal, upon buying this plant I was stabbed by the sharp spiny leave and it really hurts, so take extra care, once it's sited, leave it.

Although this plant can be grown in the UK, it does not seem to be very popular - possibly the vicious spiked leaves put people off. I wonder - if a visitor was injured could they sue you?
If your winters are too cold to grow Cordyline australis, then this is a good look alike - although it rarely branches much --instead it produces clusters of trunks.
In the UK it can be damaged at temperatures below -10C, but the sidegrowths or'pups' will soon take over. It has been crossed with Y flaccida to produce Y recurvifolia, and Y filamentosa to produce Y gloriosa.

I love this plant because it grows much faster than other yuccas and produces dozens of offsets ('pups' or 'toes').
Since I now have a bigger garden I would like to grow a huge thicket of them. A... read more

I live in East central IL and am wondering what time of year it is appropriate to divide and transplant the Yucca. We have a very elderly clump of it growing down the road at an old farmstead and want to move it soon. Does anyone recommend moving and planting it in the fall? I'm sorry if this is not the correct place to post this.

I live in northeast Tennessee @ 1500 ft. elevation and have had great success with this plant, even in a more shaded area. In full sun, it would probably be amazing.

If you're someone that has a brown thumb and the worst soil possible, than this is the plant for you! All you have to do is dig a clump and sit it on the ground where you want it, that's it. I have been stuck by mine plenty of times when weeding around it but I still find it an enjoyable plant.

Spanish Bayonet has several positives. It is attractive and the bloom stalk is particularly nice. It will grow happily in the hottest, brightest part of the yard; it will also grow on soil where nothing else will. It spreads through shoots at the base of the plant, but it is also easy to propogate; simply cut a piece into sections, set them on bare ground, and give them a little water. They will take root very quickly.

But there is a reason that many people plant it under windows to discourage intruders. It is an extremely formidable plant, and the needle-like leaftips will puncture even the toughest protective gear. It can also be a significant hazard to yard work; I can't count the times I've backed into it when mowing the lawn. I would very specifically warn agains... read more

My Mother was an avid gardener in South Louisiana, and she really liked succulent and cactus type plants. Spanish Bayonet was one of her favorite plants to use as a barrier along a fence line, mostly to punctuate the corners of the property. She felt that they discouraged both children and dogs from coming into her yard and disturbing her plants and cats.

She always kept them up and they never looked brown or unsightly. They also never got taller than pruning range, so I suspect she kept them cut down to a reasonable height. I was just a child, so I don't really remember.

My Mother was of the school that thinks that good fences make good neighbors, but she always had something attractive and/or barrier like growing up on her ugly chain link fences, lik... read more

First of all, my spainsh bayonets survive in central new york state. My neighbors cannot believe I have them. I was very excited to put them in five years ago. I chose them because I wanted my corner driveway garden to be drought tolerant. My hose does not go that far and we cannot waste water since we have a shallow well. Now they are out of control and I need to move them. Three grew into more somehow. They are also taller than my burning bush which is behind them. I guess I have mixed feelings about these interesting plants. I don't know where to place them. Any ideas?

Growing this yucca is a challenge for where I live in Southern New Jersey, however it does perfectly fine in Southern New Jersey coastal towns. I've had mixed results ovewintering aloifolia over the years with some years no problems, and other years, some amount of damage. It seems I am right on the edge of where this yucca will comfortably grow. Last winter (2002/03) for example, was a very cold and wet winter. An aloifolia I had growing in a southern exposure against a south facing wall had no leaf damage, but the growth spear rotted on me when the weather started getting warmer in the spring. The spear eventually pulled away from the stem and some upper stem rot started to occur. I applied a fungicide and eventually the rot stopped and the growth started up again. But because there was ... read more

This yucca is found all over the east bay of the San Francisco bay area. If looked after, it offers some beauty. Left unattended, it grows tall and spreads. I see it more in the 20' range and taller - not 10' as listed.

Once established, it is likely permanent. Cutting it down, digging it up - some part of it will survive about anything. Even if you feel you've successfully conquered it, root can sit dormant for up to 10 years - then reappear.

Leaves are very sharp and contain an oil or fiber that causes irritation if it breaks your skin.

Where I live in El Sobrante, one could not go 1/4 mile in any direction without seeing this yucca at least once.


On Nov 1, 2003, astanton from Anaheim, CA (Zone 10b) wrote:

Around the roots of this tree, hundreds of little white bulbs mature at once spreading like rhizoms, which seem to all be baby yucca trees! It is impossible to get rid of them and they grow through whatever else you planted there. The spread is up to 4 feet from the base of the tree itself, half the height of the tree--my tree is about 8 feet tall now, we started it from a baby-on-the-trunk 7 years ago.

It appears that yucca trees spread several ways: babies grown on the trunk of the mature tree, seeds, and rhizomous-bulbs that they self-create around their roots. It is quite unpleasant trying to get rid of them once they established well and like where they are!

I was sucessful planting this from seeds. I collected mature pods and let them dry. Then I ripened the seeds and placed them on the surface of a pot filled with well-drained organic soil. After a week or ten days, new plants were growing. In the first days you have to water it regularly, once every five days to a week, depending on the weather. After the first transplanting you can water them less frequently. Keep them always in full sun.


On Oct 2, 2001, Floridian from Lutz, FL (Zone 9b) wrote:

Spanish Bayonet has an erect trunk armed with sharp pointed straplike leaves each about 2' long. The young leaves near the growing tip stand erect; older ones are reflexed downward, and the oldest wither and turn brown, hanging around the lower trunk like an Hawaiian skirt. The tip of the trunk develops a long spike of white flowers. Spanish Bayonet also produces new buds, or offshoots, near the base of the trunk, forming a thicket.

It is native to coastal areas from North Carolina to Mexico and in the West Indies and will flourish in full sun with light, sandy soil. Spanish bayonet may be the ultimate in "security plants" - it can be planted beneath windows and other access points where its fiercely pointed leaves will prevent passage of all interlopers human and otherw... read more
