Letting annuals reseed in your garden is a great way to fill in spaces and cut down on the expense of buying annual plants every year! The trick is to be aware of new seedlings when preparing your flower beds for planting in early summer. Some seedlings don’t germinate until the soil has warmed up – so be patient! Patches of new seedlings may need to be thinned out  and can be easily moved when they are 2-3” tall. Some varieties that we have had good luck with are the following:

  • Verbena – “Bonariensus” reseeds very readily but other varieties can also reseed
  • Rudbeckia – you may know them as black-eyed susans; however, what you may not know is that there are 23 species of Rudbeckia and even annual or biennial varieties may winter over from plants left in the ground or reseed — we’ve had luck with “Prairie Sun,” “Indian Summer” and “Autumn Colors” varieties
  • Gomphrena
  • Ageratum – especially the taller varieties such as “Blue Horizon”
  • Cleome
  • Nicotiana – especially the taller varieties such as “Sylvestris” “Nicki” and ”Heaven Scent”
  • Alyssum
  • Heleniumwe’ve had luck with Helenium “Dakota Gold”
  • Calendula  – also called pot marigolds
  • Zinnia “Augustifolia”
  • Cosmos
  • Antirrhinum – you may know them as snapdragons  – will sometimes winter over from the plants left in the ground, and also reseeds

These reseeding plants have helped to reduce our overall flower bill. I hope that it will help you too. Happy gardening!
