If I were made in charge of the gardening realm, the first change I’d make would be getting rid of waiting times to get blooms. I’d ensure whatever is planted starts blooming instantly. 

Although this is just my impossible fantasy, there are some fast-blooming flowers out there that can actually start blooming in less than 2 months! 

In today’s article, let’s take a look at 12 fast-blooming flowers that can help fill your garden with mesmerizing color. Keep in mind that these flowers typically bloom within 40-60 days after germination, especially when grown in warm, sunny conditions. 

Zinnias
  • Perfect For Late Starters

Fast-blooming flowers are ideal for those who missed spring planting. If you have any unwanted gaps and empty spaces in your garden, cover them up by planting these flowers. 

  • Instant Gratification For New Gardeners

If you haven’t fully mastered patience yet, flowers that bloom quickly can help build confidence and give you a quick boost of motivation.

  • Keep The Garden Colorful All Season

Fast-blooming perennials often have succession planting potential, and many can even rebloom with some light deadheading.

Though these aren’t very popular flowers, Godetia blooms offer unique petals and bold colors in less than 55 days. However, they must be given full sun for complete growth. 

Impatiens

Okay, this one’s kind of cheating… don’t be mad at me! You’ll need to start with nursery transplants or starts to see fast results. But honestly, impatiens are just too gorgeous (and come such bright colors) that I had to slide them into this list.

From transplants, they’ll start blooming in just 14-21 days. They’re a great and reliable choice for shady garden spots.

If you try growing them from seed, though, you’re looking at 85–90 day, so stick to starts if you want quick color.

Flower seedlings
  • Start seeds indoors, ideally in warm soil. Germination is faster in warm, loose soil or seed trays.
  • Use a balanced fertilizer after germination. Apply as directed on the fertilizer package; no need to conduct experiments on your own.
  • Avoid using overly nitrogen-heavy fertilizers as they can encourage excessive leafy growth at the cost of proper blooming. If anything, a higher phosphorus concentration can support better bloom development.
  • Deadhead early bloomers. This keeps the plant from going to seed, potentially encouraging a decent rebloom.

I’ve always said that gardening is the hobby of the patient. Growing the best flowers and plants can take months and even years of practice and learning! 

However, if you’re someone who’s still in the process of acquiring patience, fast-blooming flowers can be a solid way to build your confidence and obtain proof that gardening is not the complex, troublesome hobby it’s typically made out to be.

Embarking on this journey of growing quick flowers can also equip you with the skills and planting knowledge you need to progress in the realm of gardening later on, acting as a sort of “practice round”.
