Olbrich Botanical Gardens continues to be a leader in sustainable gardening in the Midwest, by choosing plants that are not only beautiful and well-adapted to the conditions of their sites, but also good for our planet. Plant species incorporated at Olbrich are selected for their innate ability to enhance our environment and contribute to the food web that supports insects of all kinds, which then support small reptiles, amphibians, mammals, and birds.

How do these new plant offerings support the Gardens' mission?

  • Reduced plastic waste
    • Plant plugs share a single tray versus individual pots.
  • Reduced fossil fuels
    • Plug trays help fit many plants in a small space for shipping.
  • Strong root systems
    • Plugs - small soil volume and vertical design of each plug promotes healthy rooting, with lots of roots supporting a relatively small mass of top growth.
  • Value - Good for the planet & good for YOU!
    • Reducing growing supplies and shipping costs = good prices!

We have a saying when using plugs,

"Buy the plant, not the pot and soil"

All proceeds directly benefit the mission and daily operations of Olbrich Botanical Gardens!
