Grown tall

I think we've had them for nearly forty years now it was at local fair that you could buy wee little cactuses in a pot. And our then four or five year old son ( now forty something) wanted one. See what has become of it. The smaller one by the way is the original and the taller one is the offshoot! When we started our small flat in a turn- the- century building and high ceilings the two of them came with us - very different, but we managed to transport them in our car. The taller one wouldn't fit in it today!
