Making a fall gardening checklist

Fall is nearly upon us, and while many gardeners lament the end of the growing season, plenty of work remains to be done before winter sets in. I actually enjoy fall gardening tasks as they are a way to end the year with a bang and get all set to hit the ground running in spring. Here is a short...

Pink surprise lily flowers

Surprise lilies shock with late bloom

When I try to think of plants that live up to their common name, surprise lily (Lycoris squamigera) tops the list.  In fact, this plant has quite a few common names that are equally fitting, including ghost lily, magic lily, resurrection flower, naked lily, and mystery lily, among many...

Using wild columbine at home

During the flowering lull of late spring in my home gardens, I often admire the unique, dangling blooms of our native wild columbine (Aquilegia canadensis).  This plant occurs in nearly every county of Illinois and its native range spans the Eastern US, from Florida and Texas to Canada. ...

Ants on a Peony

How ants help peonies

In the plant world, insects can be considered either friend or foe based on their status as beneficial partners or pests.  We often think of pollinators as the primary friends plants have in the insect world, but there are certainly other beneficial insects that don’t necessarily pollinate flowers...

Throughout the fall season, garden centers are filled with a beautiful selection of mums (short for chrysanthemums).   In the garden, mums provide a both a spectacular fall display and a late season nectar source for pollinating insects.  It is a wonderful time to plant these attractive, fall-...

Deicing Salts and Plant Damage

While this winter has brought little ice and snow cover, this past weekend’s winter weather put a coating of ice on most smooth surfaces.  Gardeners, businesses, parks and others with landscaping near walkways must apply deicing salts for safety, but these products can harm plant life.  Deicing...

Flowering herbs provide ornamental beauty to the edge of this pollinator garden

Grow herb gardens for more than the kitchen

Herbs are a wonderful garden addition that provide easily accessible, fresh herbs for culinary use. However, I find that herbs are too often overlooked in most garden plans and can really provide a ton of ornamental and ecological benefits as well.  In general, herbs are pretty tough plants and do...

Standing dead stems are important overwintering habitat that should not be removed from the garden until insects emerge later in spring.

Spring Garden Cleanup

This past week’s warmer weather has been an exhilarating blast of spring when contrasted with the icy, extreme cold just one week earlier.  The warmup has spurred many of us to get back out in the garden to start getting ready for spring.  While our landscape beds and gardens will be places of...

Pollinator Pockets

Hand pollination of last year’s hosta flowers produced the seeds used to grow this tray of hosta seedlings.  However, it will take a few more years for these plants to mature and truly express the traits gained from hybridization. Photo credit: Barb and Rick Schroeder

Hostas

Plants in the genus Hosta, collectively referred to as hostas, are one of the premier plants for ornamental gardens that lack full sun.  These resilient perennials are a mainstay of Midwestern shade gardens and remain popular in temperate regions worldwide. However, that wasn’t always the...

The tufted seedheads of reed canary grass are easily noticed this time of year.

Plant Phenology for Identification

There are so many plants in nature that tend to reveal themselves during some kind of phenological event, such as flowering or fruit set, and then scream for attention.   For example, consider Joe-pye weed (Eutrochium purpureum), which one of my favorite native wildflowers, frequenting the partial...

Landscaping with native grasses

Nothing beats the light and airy look of tall, distinctive grasses in a landscape arrangement. The fluffy seedheads and slender, and attractive stems practically dance in the wind on breezy days, adding texture as well as a structural element to any landscape bed.    For many years, there was a...

Bluebells are a beautiful native wildflower that adds a splash of blueish-purple to both woodlands and landscape gardens in spring.

Virginia Bluebells

We all have our favorite spring wildflowers for one reason or another. Maybe they are part of a native plant community we visit often, such as a close-by natural area or favorite park trail?  Perhaps our preference comes from the plants we are able to cultivate at home, in our own gardens?  For me...

Daylilies

This time of year, daylilies are far from the center of attention in most landscapes.  The beautiful, vibrant flowers that adorn the scapes of most traditional varieties earlier in summer have long faded, leaving a much less interesting plant that very much resembles a clump of grass. As their name...

Butterfly milkweed is the only Illinois milkweed with orange flowers, which provide a showy display each summer, often blooming a second time around early

Illinois has an Abundance of Milkweeds

In recent years, milkweeds have gained attention from the public due to their exclusive relationship with the imperiled monarch butterfly. I think many of us are familiar with common milkweed (Asclepius syriaca), which reminds me of childhood leaf picking experiments to see the characteristic sap...

Buttonbush

I always love it when a particular plant that I know from the natural world doubles as a landscape plant.  Not everything that is beautiful in nature can handle what we throw at it in human landscapes, some native plants are just too sensitive.  However, one old favorite of mine from wetland...

The ‘Annabelle’ hydrangea is a cultivar that was originally collected from a wild specimen in southern Illinois and remains one of the most popular in production today.

The 'Annabelle' Hydrangea

The ‘Annabelle’ hydrangea has been a mainstay of the ornamental shrub world since its release in the 1960’s.  This showy shrub is filled with beautiful snowball-like flowers that adorn its spindly branches each summer.  The blooms begin as pretty green puffs that turn white at maturity, often...

Houseplants and Indoor Air Quality
