Two Heads Are Better Than One

P80221Three or four might be better than two. Perhaps that is what this queen palm was thinking when it decided to get extras.

This is not a good picture, and the tree is a bit too shaggy with old foliage to see what is going on inside clearly. To the left, a secondary limb is curving downward and away from the main trunk, before curving back upward as a secondary canopy. Another limb is developing immediately above this secondary canopy, and another is visible to the right of the main trunk. It is hard to say how many individual canopies are within the collective canopy of this single specimen.

What is weird about this development is that the popularly available palms do not form branches. Think of it. When was the last time you saw a palm tree with a limb or branches? Before you answer that, yuccas (such as Joshua trees) and dracaenas are not palms. Also, clumping palms like Mediterranean fan palm do not form limbs from their main trunks. They merely develop multiple trunks from basal pups.

The very few specie of palm that develop branches regularly are very rare and live very far away. Date palms, either grown for dates or recycled into landscapes from displaced date orchards, have the potential to develop pups higher on their trunks, but rarely do so.

Palms are only trees because they have trunks. Otherwise, they are merely really big perennials, with single terminal buds from which all their foliage, flowers and fruit develop. If deprived of the terminal bud, a palm can not generate a new one, which is why a palm will die if topped.

So why does this queen palm have more than one terminal bud? It is impossible to say.

Bastards!

P71011Palm trees did not impress me much when I was young. Although striking in the right landscapes, they did not ‘do’ much. They made no fruit. They made no firewood. Only the big Canary Island date palms made any significant shade. What they did make was a big mess that was difficult to rake. They were expensive to maintain. They sheltered rats and pigeons. Their seedlings came up in the weirdest places.

Back then, the only two palms that I was really familiar with were the Canary Island date palm and the Mexican fan palm. Windmill palms were common too, but because they are so much less obtrusive, they did not get my attention. Queen palms had not yet become a fad, so were mostly in older neighborhoods outside of my world. I was aware that there was an odd type of Mexican fan palm, but never gave it much thought.

Then I went to college . . . and met Brent, from Southern California, where palms are more appreciated. I also met more palms that I had either ignored earlier, or had never seen before. After a while, Brent showed me around coastal Southern California, including the Pacific Coast Highway and Santa Monica, where I saw palm trees at their best.

I will never forget turning onto Bedford Drive in Beverly Hills, where the Beverly Hillbillies drove when they came to town. I had never seen Canary Island date palms and Mexican fan palms like that before. They were so majestic! They were so tall! They were so uniform! It did not change what I already knew about palms, but it did give me a different respect for them.

That odd Mexican fan palm that I mentioned earlier was actually the California fan palm, or the desert fan palm, which is classified as a distinct specie. It gets about half as tall, but twice as stout, with fluffier foliage. Because it is shorter and stouter, it stands straight, without bending like the taller and lankier Mexican fan palm does. It is also more genetically variable because it naturally grows in isolated oases rather than a contiguous range.

After seeing the California fan palm growing wild outside of Palm Springs, around the springs that Palm Springs is named for, it became my favorite palm. It is very stately in the right situations. It lines North First Street at Saint James Park in San Jose, and flanks the Palm Driveway at the Winchester House. Unfortunately, it really prefers to be out in the aridity and warmth of the desert. It looks rather sickly if it gets too much water.

While cruising around the Los Angeles area, Brent pointed out a few ‘bastards’, which are hybrids of California fan palm and Mexican fan palm. Apparently, they are not distinct specie, but rather subspecie. In other words, they hybridize freely. Each parent has attributes; and the bastards get the best of both.

Mexican fan palms, whether I like them or not, are very tall, elegant and graceful. They are exquisite skyline trees, with leaning or bowing trunks that can move casually in the wind. California fan palms are stout, stately and formal. If not watered too much, their straight and uniform trunks, and canopies of fluffy foliage, work nicely where conformity is desired. Bastards have trunks that are just thin enough to be elegant, but just stout and straight enough to be stately. Their canopies are more ‘lush’ than fluffy like those of the California fan palm.

Until recently, bastards were solitary trees that grew randomly from seed. They were not available in nurseries. If they had been, they would have been very variable because of their random breeding. However, someone took notice enough to cultivate what seems to be a cultivar known as Washingtonia X filibusta. (Washingtonia X filibusta is derived from the names of California fan palm, Washingtonia filifera, and Mexican fan palm, Washingtonia robusta. The ‘X’ designates it as a hybrid.) They are becoming the new alternative to the formerly all too common Mexican fan palm.P71011+
