Flowers For Hot Weather – Useful Guide

Are you finally satisfied with the look of your garden? Well, have you considered what to do when hot weather comes? Will your effort go to the drain as your flowers slowly start to wilt on hot summer days?

It doesn’t have to be this way!

If you live in a hot climate, you need to choose flowers that are heat resistant.

The key is knowing what and when to plant. That’s why we made a list of the best plants for hot weather. We hope our suggestion will help you make the right decision.

How to grow heat-tolerant flowers?

Growing colorful flowers in a hot climate pose particular challenges. A lot of plants soar when the temperature goes up. While an occasional hot day or a hot week isn’t that bad, imagine living somewhere where temperatures reach extreme levels.

By the end of the day, your flowers will wilt and dry. Also, when you can’t expect respite from the heat at night, for instance, in hot and humid regions, the effects are even worse.

However, if you choose hot weather plants and flowers, you will have much more success in keeping your garden colorful during the summer. Some species are more tolerant than others, and you can use them as annuals when other plants stop flowering.

Can you protect your flowers from the heat?

While heat-resistant flowers don’t require some special protection, it’s better to be safe than sorry. Here are a couple of things you can do to protect your plants from high temperatures.

Add mulch

It’s essential to keep the plant’s roots cool, especially on hot summer days. For instance, you can spread an about 2-inch layer of mulch, which helps soil retain moisture and maintain an optimal temperature level. Be aware that dark mulch will absorb more heat while lighter one will help the soil stay cooler.


If you have bedded annuals, make sure to add at least one inch of water per week. On the other hand, containers require more since they are above the ground and are more susceptible to winds. You can use a drip system if you have one for easy and consistent watering. Only water in the early morning.

Provide shade

If you add shade-producing shrubs, trees, and other structures to your landscape, you will lower down the surface temperatures and reduce heat in your yard. Did you know that shaded surfaces can be up to 45 degrees cooler than the exposed part of the yard?
