Seeds of Luffa by post

I'm a member of a facebook group for Portuguese speakers on facebook (I'm Portuguese) and one of the ladies is planting Luffa in her garden and she promises to send seeds to people that would send her a letter with a envelope and a stamp for her to send a couple of seeds to us!

I'm going to try it out! 

I hope that she sends me some seeds and I get to plant some vegetable sponges in my garden!
