    Mad customer

    I ordered this to go for a centerpiece at a party I was throwing. I expected it to look like the pictures and be covered in flowers. However, there was only 1 tiny little flower on this bush when I received it. Not happy!

    Roses are Red

    Order 2 of these plants. I was skeptical because I have never heard of this website before. I was very happy with the quality of each plant when they arrived at my doorstep. A little pricey with shipping costs though.
