Hello again, I have been given these cacti. There are two kinds, and despite searching everywhere (even in the http://cactiguide.com/ website) I cannot identify them. Does anyone here have a clue what they are? I have put my hand in the pictures so you can see what kind of size they are. The first, small one is supposed to be capable of blooming in the summer, but I have not personally witnessed this and do not know what colour that bloom would be. [edit: additional info, on its two "knobs", the spikes are a bright orange colour.] The two taller ones, well, there's not much to say about them, but I like them very much. :D [edit: their spikes are covered in some kind of white fluffy stuff, and they sting, like really sting, they will get in your skin and never let go.] Thank you!
Hi, Not sure of the first pic but the two taller ones are Acanthocereus tetragonus 'Fairy Castle Cactus' Darren
