When designing a bouquet of plants, there are a few things to consider: shapes, colors, and types.
None of the flowers used in this pot are the same color. The bottom layer has plants with dark purple green leaves. Since they are dark by nature, the shadows that fall onto them don’t dim their color. The center of the arrangement has light green leaves, the lightest plants used in the whole bouquet. To ease up on the bright colors, the white green colored plants were used at the sides. To top it off, green fern like plants and purple plants were used. The purple plants used emphasized the purple of the bottom layer of the plants; otherwise, it would just look gray.
The leaf types are different for each plant. The center plant has the largest leaves, drawing the eye to that area. The bottom layer of plants has small rounded leaves that contrast with the larger ones. The top layers are different with a purple flower that has feather like leaves and a fern-like plant. To connect the layers, the tiny flowers are used on each side.
Lastly, each of the flowers used in the pot have the same or similar environments. They like to live in the shade, likely have the same water needs, and other similarities. This makes it easier to care for the pot. You don’t have to worry that adding something to help one plant may hurt the other.
To recreate a grouping of plants like the one in the picture, you would have to use similar ideas in your pot. Consider all the different possibilities in advance, before you set out to make it a reality.
