    Testimonials

    ★★★★★

    This shop has great customer service. Although they mainly sell pots they also have a few plants to sell. I bought one of these plants and it shipped very fast. The plant I received is beautiful but it was the wrong plant. I contacted the shop right away. I told them I will keep the plant but I’d still want to buy the one I wanted. The plant I wanted also cost less so I offered to pay the difference too. The shop apologized for the mistake and said they will send the right plant right away and to keep the plant i already received. I thought that was awesome, thoughtful and very professional and that goes a long way. Thank you so much and I really appreciate that.

    Simply a beautiful and artistic Peety pot. Will be the pot for an Adenia metamorpha and the two will definitely display awesome artistry.
