segmented cholla

This was another cactus I found intriguing. I think it's either a Buckhorn or Staghorn Cholla. It grows in segments, that branch rather evenly, and looks pretty brown and dull. You have to look close to see the spines.

The end of the branches bulge out into the fruits and I'm guessing that's where it flowers, too. But I didn't see any flowering so couldn't identify them more specifically.

My sketches of this one are just the general shape and growing habit (of the one in the front yard at the house we visited), it doesn't have a lot of definition- for example, the stems have an interesting texture with even bulges rather like a quilted jacket or old-fashioned upholstery with lots of buttons in it! (except of course these have spines). Search out images with closeup of buckhorn cholla and you'll see what I mean.

agave

One of my other favorite cacti were the Agaves. I don't know the name of their varieties, but this one was a pretty blue-green with faint horizontal stripes on the leaves, and tiny spines on their margins.

These two pups were growing near the big one pictured above.

There was another plant with small, dark low-growing leaves hardly noticeable because the bright red flowers carried above them so attractive.

cholla

The chain-link Cholla cactus develops clusters of hanging fruits and segments drop off which can grow into new plants. The spines are dangerous to feet. It's also called the jumping cholla.

ocotillo

My favorite cactus was the Ocotillo. Wikipedia tells me this is not a true cactus. It dries out to seemingly-dead brown stems with spines, but when rain comes small round leaves emerge all along the stems. It flowers with bright red feathery blooms, one atop each stem. The plants were just starting to bloom when we saw them (but not the individual in front of the house which I sketched).

prickly pear

One type of cactus we saw a lot of in the desert was the Prickly Pear. There were smaller ones with a darker green color and shorter, denser spines and also pretty purple ones.

Some of them had curiously oblong triangular shaped pads, instead of round.

stout cacti

There were lots of short, fat cacti in AZ. Some are barrel cactus, with bright flowers on top. Others I thought were baby saguaros, but not sure. Some had pink flowers, others yellow, I assume depending on the species although I don't know the difference.

These are not really striped, I was trying to sketch the definition of the ribs.
