A Blossom and Some Blush

I don't know what this plant is called, it's doing fine and
todat I noticed its tiny, white flowers almost blanketed by
the lush green leaves.

Another variety that's been growing here for the past5/6 years.
The pretty white flower bloomed today and suddenly I felt that
the plant isn't as wild-looking as I'd assumed it to be!

A tinge of red and the blooms start to arrive on this euphorbia.
With more of green than any splash of colour in my yard, this is
very, very welcome!

In India, this must be the most-planted bougainvillea! When the
colour comes, it's orange but the veins on the bracts show its
future--magenta!
