15 Of The Easiest And Fastest-Growing Flowers For Impatient Gardeners

Farmers, gardeners, and others who work the land full time know what an arduous process growing and cultivating can be. And when us non-green thumbs see the final results on our Pinterest or Instagram feed, we might envy the gorgeous flower beds and perfect fruits and vegetables we see. We might also get dangerously inspired — which leads many to begin starting a garden of their own, blissfully ignorant as to how much time it really does take to grow a healthy, thriving outdoor area. 

The good news? If you're a busy person with a jam-packed schedule — or honestly just admittedly impatient — there are plenty of flowers you can grow quickly and easily. Gardening will teach you the value of slowing down and enjoying the little things, but, fortunately, there are still some beautiful instant (almost) gratification options for those of us who thrive off quick results. According to Garden Fundamentals, you can make flowers grow even faster by starting them off in containers indoors while you're waiting for that final frost to pass.

Zinnias (Zinnia sp) are true show-offs in any garden. According to American Meadows, zinnias can grow either low to the ground or boldly tall, and come in an impressive variety of colors.

Zinnias like warmer climates if they're growing in the shade, but there are plenty of climates in which they'll do just fine.
