While I was hiking, someone pointed out that a trained observer can tell the difference between masculine and feminine ocotillo plants. This thought had never occurred to me. Is this true? My friend said the masculine plants are streamlined and straight, whereas the feminine plants spread out and are more open. Is this true or simply a wives' tale?
No this is not true. There is not a female and male plant.
The plant is pollinated by Carpenter Bees and Humming Birds.
After the ocotillo is grown to 10' or more, how do you keep it growing straight up? We have 3 ocotillos. The first one curves gently at the bottom in an upward pattern. It remains with all branches growing straight up. The 2nd and 3rd ones look like something came down onto the top of them and tried to flatten them. How do we keep the canes growing straight up after curving up from the bottom?
Yes, you can stake the Ocotillo if necessary.

It has been healthy and producing flames regularly for 8 years. The conditions have not changed.
Yellowing leaves could indicate watering issues, to much or to little, nutrient concerns and possible insects.
Scale can become an issue for Ocotillos and they are a sucking insect.
The use of an insecticidal soap should clear them up.
Here is a link to refresh you on the care requirements.

I have an ocotillo that is 13 years old and it grows what I would call suckers. They grow off of a stem and grows down. If I let them go, the plant ends up looking like an octopus. I have never seen one in the wild do that and I have asked the nursery that I bought if from and they do not know what causes it or what to do about it.
A mature Ocotillo can grow to 15 feet tall and the same width.
It is not uncommon for the plant to send out canes that will lie close to the ground as the base widens.
A mature plant can grow up to 60 canes or branches.

Can ocotillo be planted in large pots?
My research has turned up virtually no information on growing an Ocotillo in a container.
The reason is clearly due to the size that this plant can grow too, and the specific growing conditions needed.
Ocotillo would need to be planted in ground for success it would seem.
Here are some articles with more information.

I have yet to get one orange bloom on my ocotillo. I planted it bare root 10 years ago on south slope of natural Tucson desert amongst many mature Saguaro. It performs like all ocotillo, green leaves at appropriate times just never a bloom? What can I do to get it to bloom? P.S. There are no native ocotillo on the slope just saguaro O'Mara in Tucson
Bare roots can take longer to form roots though they should have become established within 2 years.
Watering is very important for the Ocotillo. In warm months it will need to be watered every 2 to 3 weeks.
In cold weather water every 3 months. Water should be well draining.
I would try increasing watering to see if this can encourage flowering.

We bought this house 5 years ago, and there are 5 or 6 ocotillo around the front and back yard. It seems like in the first year they greened up with leaves in the spring. They are no longer doing that. They are on our drip system. I have never fertilized them because I thought they didn't need it. Would love to have them green up, what do I need to do? Thanks so much for any help, Una Loge.
Ocotillos are a bit unusual because they can survive for long periods and even flower without leaves. Often they will photosynthesize using the green parts of the stem.
Giving them more water can encourage them to leaf out, but it's not guaranteed. The best way is to water them at the base and also the surrounding area, since the roots spread out pretty far around the stem.
