In the world of gardening, there’s something to be said for instant gratification. While the slow, steady growth can be deeply rewarding, sometimes we gardeners crave a quicker payoff. In this blog post,we’ll introduce you to the best fast-growing plants that can transform a bare patch of soil into a vibrant, colorful display in a matter of weeks.

Annuals

Within 4-6 weeks, the plants will be covered in vibrant flowers in shades of yellow, orange, and red. Marigolds are also incredibly easy to grow, thriving in poor soil and hot, dry conditions that would send many other plants into a sulk.
