Central Phoenix -- Two specimens grow in the ground in my garden. One is 25 years old, but still fairly small. It grows in full shade winter & summer, with monthly summer water and none in winter, and is under a winter cold frame. It is quite etiolated and seldom blooms. A two year old plant in the same bed, but in full afternoon summer sun is almost as big.

While amazingly beautiful when grown well, I've had a bugger of a time with this plant and found it one of my most demanding aloes. Too much heat= rot. Too little heat= rot. Grow it dry and it shrivels and sulks; give it water = rot. I have all the other members in this striata complex of species and none of them have given me the slightest trouble, kouebokkeveldensis included.

I'm on my third plant and will give up when this one inevitably croaks, confining myself to drooling over the huge and impossibly gorgeous specimen in the local Bot Garden glasshouse.

I suspect they're best grown in the ground as opposed to a pot. Oh well.

Great plant that, like the related Aloe striata, tolerates the Arizona heat and frosts very well. It also flowers in summer when not much is going on! Too much sun will bleach it out and you'll lose the pretty lines in the leaves, but too little will make it grow entirely out of proportion. The plants here are kept under shade cloth in summer that is removed in the milder months. I would imagine that morning sun would also suit this plant well, but avoid trees whose canopy is too dense.

This is a slightly larger, longer leaved version of striata with prominent, very ornamental, thin lines along the leaves. Large plants look very attractive. This one has small teeth along the leaf margins (A striata usually is smooth along the leaf edges). Flowers multiple times a year. Flowers are a bit roser colored (A striata usually bright orange). South African native- this variety is not endangered.
