Use the verb burgeon to describe something that is growing, expanding, and flourishing. If you have a green thumb, in the spring your flower gardens may burgeon. If you don't have a green thumb, your collection of plastic plants may burgeon.
Although burgeon means to grow and flourish, it doesn't necessarily have to apply only to plants. Your town can have burgeoning downtown development. Your tiny retirement account can burgeon into an excellent emergency fund if you invest even a small amount each month. You may have a burgeoning career as a villain if you overthrow a planet by using your mind-controlling ray gun on the populace.
