Happy Valentine’s Day!

Looking for something more special than “just” a bunch of flowers? Read my post at the “Annals of Botany” blog to find out how to make rainbow roses.

    I’ve seen these flowers before and loved them but didn’t realize its easy to do it at home :) I will have to experiment with some different species of white flowers and colours see how they turn out…I’ll send pictures!

    Petra, you should do a guest post and try this and definitely take pictures! Maybe we can do it at work and start it in a lunch break, and then look at the flowers the next day. :)
