zinnias at Annie's Annuals

by Trisha Shirey

  • Heat-loving, drought-tolerant annuals
  • Zinnias trace their parentage to South America and South Texas
  • Require well-drained soil
  • Sun or afternoon shade. Zinnias will not perform well in semi-shade.
  • Butterflies love them!? Plant in containers on the patio or porch for a close-up view.
  • If possible, water by hand or with drip irrigation. Early-morning sprinklers will wash away nectar that attracts the butterflies.
  • Easy to start from seed, or get nursery transplants
  • Plant after soil has warmed up in late spring/early summer
  • You can keep seeding throughout summer
  • Fertilize regularly to promote top performance all summer
