Which plant genus includes popular bedding plants known for their heat tolerance and ability to bloom profusely?

The plant genus known for popular bedding plants that demonstrate exceptional heat tolerance and prolific blooming is Petunia. These plants are highly regarded for their vibrant colors and ability to thrive in warm conditions, often making them a favorite for ornamental displays in gardens and landscapes. Petunias can bloom continuously throughout the growing season, providing a long-lasting display of flowers. This resilience to heat and ability to produce abundant blooms is a key reason why they are commonly chosen for bedding plant applications in various horticultural settings.

Other options, while also familiar bedding plants, may not focus specifically on the combination of heat tolerance and prolific blooming to the same extent as Petunia. Geraniums, for instance, are popular but may not thrive in extreme heat conditions as successfully. Coleus is appreciated more for its foliage than for blooming profusely. Sutera (also known as Bacopa) is often used as a trailing plant but does not have the same robust blooming characteristics under hot conditions. Thus, Petunia stands out as the leading choice for these attributes.
