• Smaller alternatives to the traditional tree,
• Poinsettias are another classic holiday plant. Upsize from one or two by the fireside by stacking them in a tiered or pyramid shape. One of those trendy tiered ladder shelves can help you create your display, or simply stack your plants on a series of gift-wrapped (empty) boxes.
• Take the vertical garden idea farther and create a tree wall mural with hanging wall planters. Plenty of styles are available from your favorite retailer and can be used for potted plants, houseplant cuttings in water, or even air plants.
• Create a succulent tree with a florist foam cone shape, and cover it in damp sheet moss. Using florist pins, attach small succulents to cover the cone. To keep costs down, try using hens and chicks or cuttings from sedum. Keep it misted during the winter to keep it fresh. You can even replant the cuttings in the garden next year if they root.
