If you are short on ideas for a gift for a friend, or if you are organizing a dinner and want each guest to be able to take home a unique and original souvenir, why not put together a small terrarium? You need just a tiny bit of earth, an assortment of cacti, technically called succulent plants, and some lentil sprouts set into a Fido or Quattro Stagioni jar along with a few stones to make the composition a little more Zen and harmonious. How gorgeous do they look?!
