Vanilla planifolia - 4 inch pot. Growth is about 3 to 4 inches long. Solid green foliage. Greenish-yellow flower. Blooms in the spring. Not Blooming size. These will take a long time to get there (3-6 years) , but will eventually flower. Blooming plants can get quite large. The flowers last only a half day. But if you pollinate them they will produce vanilla beans which eventually, through several procedures, produce Vanilla extract. Even if you don't grow them for the Vanilla, they make attractive vine like plants. Make great coversation pieces. Like it hot and humid.
