Wow! I am glad because I did not know its name, nice flowers. I have some thing like that and I let the old vegetation mound over and every spring fresh green covers it with same sort of flowers.

Rain water is acidic and to copy nature I put in a table spoon of vinegar in five liters of water to get a PH of 6.
Bacteria thrives under acidic conditions and succulents in alkaline, so rain activates the bacteria to produce micro nutrients for the plant. That is why they bloom during spring rains
