Cluster succulents that look like extra long green beans
Poisonous Succulent Plants
Has a white sap (like sticky milk) and grows in front of the Phoenix Art Museum and many other newer landscapes in Phoenix. No thorns, no flowers (I think).
Drought Smart Plants reply:
Any plant that has sticky latex sap is potentially Euphorbia - a poisonous plant.
Without a picture, I have no way of telling you any more about the plant, as there are lots and lots of really different looking plants in the family.
This genus ranges from the Christmas Poinsettia, to Firesticks to Devils Backbone, all with varying degrees of poisonous attributes.
See more here: Euphorbia.
Please use caution with these plants.
