1. Sunflower
Despite their towering beauty and cheerful demeanor, these tall beauties can become overwhelming. Spreading seeds like wildfire, they can quickly dominate a garden space, overshadowing smaller plants. Their extensive root systems also compete aggressively for nutrients, leaving little for their floral neighbors.
