Red Flowering Cactus

I've had a quick look in google images to see if I could get the name of this type of cactus but there are millions of them!

I've had it for years and it really is beautiful! This year it is covered in buds. This flower is the only one fully opened at the moment. I've put another shot in as an extra so you can see all the buds and get an idea of the type of cactus.

A very quiet Sunday has almost ended, always goes too quickly!! :o)
