1. No cultivars: Our plants are strictly native plants, many grown from locally collected seed. We care about this because songbirds, pollinating insects, and monarch butterflies know the difference!
2. No neonicotinoids: Neonicotinoids are a class of insecticides that are particularly harmful to bees. We never use insecticides that contain neonicotinoids.
3. No secrets: Every plant we sell has been grown right here at Pleasant Prairie Nursery. Most of our plants have spent a high percentage of their growing time outdoors, not in a protected greenhouse. Our native plants are seasoned and hardy, ready for planting.
We grow many of our native plants in 2.25" wide x 5" deep plug trays. The vertical ridges of the tray direct the roots downward and prevent the circling of roots into a rootbound mass. An opening at the bottom of the plug keeps the roots air-pruned, enabling quick growth when planted.
5" plugs can easily compete with larger pots for 1st-season growth.
When you order 5" plugs, some of your plants may be in 2.5"W x 3.5"H pots.
