So I found this on Pinterest Growing Luffas blog post and I still can't believe it. How did I not know that Luffas are grown on vines, and that I could grow them?! For some reason I thought they came from the ocean, like some type of sponge. Well, now I will have to find some seeds to start and try to grow them this year. Because who WOULDNT want to grow a luffa? Amazing.
