Only 50 Plants until August

I am inspired by this. And because I'm always looking out for the best interests of my friends, I'm sharing it for your inspiration also.

But by his calculations, come August, we're going to have to add 20 more plants for the new baby. Wow! This baby is going to take up a lot of clean air!

Ok, seriously, I'm not going to buy 70 plants, but I'm thinking of starting with 10. How many do you want?
