They do like full sun but would probably flourish in east exposure..
BTW All cactus are succulents but not all succulent are cacti.
Anyway,here is some info I came across....
Because of its cactus-like appearance, Euphorbia trigona is often mistaken for a cactus. However, there are reliable criteria by which Spurge (Euphorbia) can be distinguished from cacti. The spines comes from a horny shields whereas in cacti the spines come always from "areoles" (felted cushions). Paired spines, which are typical for (a large group of) euphorbias, never occur in cacti. Conversely, the typical cactus clump of spines is never seen in euphorbias.
With respect, you appear to have taken no notice of what I wrote, but are simply reiterating the incorrect statement I was attempting to put right .enigmaticcurses1977 wrote:Correct me if I'm wrong, but isn't a cactus a type of succulent?
Areoles - the small depressions where hair, spines and flowers (also offsets) appear on members of the family Cactaceae - just look at a cactus and they are obvious.applestar wrote: "Succulence" vs. "Succulents" are these just semantics or are they specific terms? I took "succulents"/"a succulent" to mean a type of plant -- a noun.
A succulent is a plant that possesses succulence - ie has fleshy water storage tissues.
Earlier in Jim Hardy's post describing where/how the spines grow was interesting, too.
But areoles=felted cushions ....haha I'm already lost. What are felted cushions.
Not true that all cacti are succulents. Here is Pereskia aculeata growing up my garden wall. The only cactus genus with true, permanent leaves and not succulent. The presence of areoles shows it is a cactus.
