Hello, I have a plant I am told is a cactus tree. ? It starts out like a sunflower looking plant then it shoots up real tall and i mean tall it grows tiny purple flowers on it, the trunk is fuzzy with thorns or so and it actually dies after it blooms, leaving behind lots of small babies to share with friends. Help I believe that one is doing good and the other is or maybe morphing to the next stage or its dying, here the pictures.

Gosh, not sure what that really is, I have never see anything like it unless it is some type of Pereskia or maybe Jatropha?

Anywho, I think it might have had too much of something - water or perhaps sun.

I don't know what it is, but it is not a cactus.

I know, I know...at least I think so.
It's not an ECHIUM?
I had lots from seeds I received in a trade from the US, but they never liked it here (inside winter, they just died one by one).
None left.
Yes, if it is an Echium they shoot up real big flower stalks with thousands of real nice blue flowers.

Fixpix, I think you have right. Or yo're close.
I found some Echium like Echium piniana, who look similar. (Arrangement of leaves on stalk, leaf veins and how was describe the flower of the plant ...)
