s. Many garden visitors have commented that the garden gives them a lot of great ideas. A new demonstration garden was created on the Indiana State Fairgrounds in 2012 by Purdue Extension-Marion County staff and Master Gardener volunteers. The demonstration garden primarily features annual flowers and vegetables. In 2013 the Purdue Extension-Marion County Demonstration Garden became an official All-America Selections (AAS) Flower and Vegetable Display Garden. It is the only AAS Display Garden in Indianapolis and one of only a half-dozen in Indiana. An AAS Display Garden provides the public an opportunity to view the newest AAS winners in an attractive well-maintained setting. The demonstration garden is located 350 feet east of Discovery Hall where the Purdue Extension-Marion County office is located. This is in the northwest corner of the Indiana State Fairgrounds, 1202 E. 38th St., Indianapolis, IN 46205. There is no charge to view the garden or for parking for garden entrance (except during the State Fair when normal fees apply). For directions or more information on the garden, call Steve Mayer at 317-275-9290, or e-mail: [email protected].

Many thanks to all of the Marion County () Master Gardener volunteers who planned, planted, and maintained the demonstration garden on the Indiana State Fairgrounds this year! They also harvested the vegetables and delivered the produce to the food pantry. The garden would not be possible without all of their volunteer work.

The total 2025 harvest from our demonstration garden for the food pantry was 1,886 pounds, 1.7 ounces. What’s the value of the produce donation? At an estimated value of $1.97*/pound, the garden produced about $3,715 worth of nutritious food.

*=The estimated value of $1.97 is the average fair value of one pound of donated food product at the national level for fiscal year 2024, determined by the pounds received as of calendar year 2023 and studies performed by Feeding America. Note: The average value of one pound of donated product will vary from year to year based on the mix of product items donated and the current value of the product.

STEAM Theme in the “Goth Garden”: This garden area included two garden ornaments: a raven & a gargoyle sculpture (“Art”). A sign was also placed in this garden area asking a question (“Science”): Why do many plants in this area appear black? The answer related to plant pigments and their role in photosynthesis, and how anthocyanins can absorb the green light that would normally be reflected by chlorophyll, causing the leaves to appear red, purple or even black.

Goth Gardens are not just for Halloween. In one part of our garden this year, we introduced the concept of this type of gardening. Although not new, gothic gardening was listed by Garden Media Group as one of seven garden trends for 2024, according to the Greenhouse Management magazine website. This garden area featured dark foliage and also some near-black, maroon or red flowers or fruit. People liked the broad palette of dark-foliaged plant candidates for use as accents in other landscapes, too. Elements of our AAS STEAM theme in the “Goth Garden” included Science & Art.
