Factors to Consider before choosing heat-resistant flowers

Although we selected the best possible heat-resistant flowers for hanging baskets. However, all of them are not equally good for your specific outdoor conditions. You have to consider some key factors before selecting the right one.

Sunlight:

Before choosing any flowering plant, keep in mind the sun. Not all flowers withstand 6-8 hours of direct heat. Plants such as Fan Flower, Sweet Potato Vine, and Dichondra only bear full to partial sun. So, analyse the sun timings in your specific area before final flower selection.

Heat and Drought Tolerance:

In general, all the flowers enlisted in the above list are well-suited for warm weather and dry soils. However, plants like Verbena, Angelonia, Pentas, and Scaevola require consistent watering. On the other hand, Lantana, Portulaca, and Vinca can bear extreme heat and drought conditions. Therefore, choose the best suited for your conditions.

Climate Compatibility:

Although these flowers tolerate heat well, they still perform differently depending on your local climate.

• Dry climates: Lantana, Portulaca, Trailing Rosemary, and Vinca thrive with minimal water.
• Hot and humid regions: Pentas, Angelonia, and Scaevola maintain excellent flowering performance.
• Warm coastal climates: Petunias, Calibrachoa, and Verbena flourish with moderate temperatures and good air circulation.

Maintenance Requirements:

Some flowering plants require regular pruning and deadheading to maintain their bloom. While others need relatively low maintenance, so keep this in mind while selecting flowers for hanging baskets.
