This wood is cleaned, but not sandblasted, which allows the natural look to remain intact. The hole sizes vary so every piece is unique. Plants can be set into the holes or glued on top of the wood. These pieces work great with small Tillandsias such as ionantha fuego, velutina, tricolor, neglecta, brachycaulos, pseudobaileyi, chiapensis, funckiana and scaposa medium, Houston, etc. Larger amounts of wood ordered will be sent via UPS ground to save money on shipping cost. This means it will likely arrive after your plants. A bill will be sent to the email address used on your profile if any additional shipping cost is due from the additional weight. We recommend taking your plant out of the cholla to water, or only dipping the plant into the water, to preserve the integrity of the wood.
