The Chicago Botanic Garden Plant Evaluation Notes (PE Notes) are reviews of recommended plants for gardens in the Upper Midwest, as determined through scientific evaluation over a period of time -- four years for perennials, six years for shrubs and vines, and seven to ten years for trees. The program studies and recommends plants that are readily available in area nurseries.

    A Comparative Study of Joe-Pye Weeds and Their Relatives

    Over a 12-year period, the Chicago Botanic Garden evaluated 26 taxa of Eutrochium species and related genera with the goal of identifying outstanding Joe-Pye weeds for Upper Midwestern gardens.

    A Comparative Study of Cultivated Asters

    Over our 6-year trial, seven asters received five-star excellent ratings for their overall performance. Top-rated asters displayed consistently strong habits, superior flower production, excellent disease resistance, and full winter hardiness throughout a six-year evaluation term. Additionally, 19 asters received four-star good ratings for their strong performances.

    A Comparative Study of Phlox paniculata Cultivars

    From 2001 through 2009, the Chicago Botanic Garden (USDA Hardiness Zone 5b, AHS Plant Heat Zone 5) evaluated 78 Phlox taxa in full-sun trials. Download the results in this PDF.

    A Comparative Study of Tradescantia Cultivars

    Spiderworts may be pegged as common garden plants, but their unique flowers and strong habits mark them as uncommonly good garden plants. A kaleidoscopic palette of colors marks the ephemeral blossoms of Tradescantia cultivars. Just over half of the spiderworts in the study received four-star good ratings for their performance and ornamental qualities. As plants begin to turn shabby from decline or leaf spotting, shearing stems to the base will encourage a flush of new growth later in the season.

    Comparative Studies of Veronica and Veronicastrum

    Throughout spring and summer the spiky flowers of Veronica rise like sentinels in the sunny garden. Speedwells can be long-lived provided that garden soils drain freely, which is especially important during winter months. A midsummer shearing after the first bloom encourages late summer flowering. Deadheading throughout the bloom cycle produces many new, spikes later in the season.

    A Comparative Study of Platycodon grandiflorus Cultivars

    Balloonflower is a bushy, clump-forming perennial, up to 3 feet tall, with winsome buds and exuberant blossoms in midsummer. In the border or cottage garden, balloonflowers are good companions to other summer-blooming perennials and are long-lived under normal conditions.

    A Performance Appraisal of Hardy Bellflowers

    The distinctive blossoms of bellflower (Campanula) come in hues of blue and violet, from the deepest purple to softest gray blue. Grown in full sun or light shade, bellflowers are generally easy to grow and trouble free in well-drained, alkaline soils.

    A Report on Leucanthemum xsuperbum and Related Daisies

    Many new cultivars have renewed excitement in the Shasta daisy, including cultivars with frilly double flowers or thin curly petals. Plant in rich, well-drained soil: Shasta daisy is often considered a shortlived perennial, especially when grown in heavy or wet soils.
