Cactus Flowers bloom in Summer and Rain

Identical bloom or continuous bloom:

That is the question.

Are these two pictures, of same plant?

This was shot on 5th July in better lighting conditions by iPhone 5.

This was shot yesterday on 19th July 2015 with overcast sky, just after a brief drizzle.

I do not remember if it was same plant but it could be. In all probability it is. Resemblance is too striking.

If answer is yes, it means:

Cactus Flowers' bloom last more than a fortnight!

Amazing. 

See ya cacta, in a eek!
