The flowers in the first two pictures are called epiphyllum - they're a cousin to the "Christmas cactus" flowers, only the blossoms on these are about three inches across and five to six inches from leaf to end of petal.

And yea, I'm really proud of that sweet old cabbage rose. FWIW, BTW, the light green leaves behind it are the leaves of one of my two orange trees. As you can see, it's loaded with fruit. As this property is on the original adobe soil, and enjoying the benefits of the closest thing to Yavanna's own garden when it comes to climate, I have blossoms, green and ripe fruit on my citrus trees at all times of the year (which is anything but usual.)
