With summer temperatures rising, gardeners should be on the lookout for flowering plants that can withstand the hardy conditions of heat, drought, and full sun without being too much work for the owner. These five plant species are gardeners’ favorites for their low maintenance and easy growing abilities.

  • Black-eyed Susan (Rudbeckia hirta) – These flowers are easy to grow, and can do well in hot, humid conditions. A cutting halfway through the summer also promotes a second bloom towards the end of the season. As a plus, deer tend to steer clear of these plants!

  • Madagascar Periwinkle (Catharanthus roseus) – These flowers are native to India and Tropical Asia, so they thrive in both dry and humid heat. Although the Madagascar Periwinkle has a flower adapted to pollination by insects, this species is also able to self pollinate. This gives an edge to the species, allowing it to be even more tolerant of harsh environments.
  • Lantana (Lantana camara) – As one of the easiest maintained flowering plants, Lantanas flourish in drought conditions. The only requirements are plenty of sunlight and soil that drains well. They bloom all season long, and are known as butterfly magnets.

  • Portulaca (Portulaca grandiflora)– Portulacas are a perennial succulent that is both drought and heat tolerant. They are low maintenance, and are known to bloom from early summer all the way through winter!
  • Garden Phlox (Phlox paniculata)– These flowers can grow 3 to 5 feet tall, and produce sphere shaped flower heads from mid-summer to fall. Phlox can be very hardy, and in humid areas, there are mildew resistant varieties available.
