Invasive Species of the Month
Creeping Bellflower
Campanula rapunculoides
Exposure: Sun or Shade
Blooms: June-October
Bloom Color: Purple
Height: 1-3ft
An aggressive perennial weed from Eurasia. Flowers are about one inch long with five petals, nodding from one side of the stem.  Leaves are in a heart shape with fine teeth and a rough texture. Stem has hair and a purplish color. It can spread by its root system making eradication difficult. Management strategies include spraying with herbicide and manual weeding. Also known as European Bellflower or Rampion Bellflower.
 Pollinator of the Month

Common Honey Bee

Apis mellifera

Range: Throughout the United States and Southern Canada


Description: Honey Bees were brought to America from Europe to be raised commercially for the production of honey. They escaped domestication and hives can now be found in trees and hollowed places in the wild. They can live in colonies of up to 80,000 workers and the queen. They have a black head and golden brown bodies with black stripes on their abdomen. Their back legs have specialized bristles that carry pollen back to the hive. 


Pollination: Not only do honey bees pollinate flowers that produce our food, they pollinate native flowers as well. Spiderwort, Prairie Clover, Bee Balm, Purple or White Prairie Clover, Anise Hyssop, Sneezeweed, and Aster Species are just to name a few.

Why is my Restoration Changing?
The movement of plants in a restoration


Often times, restoration owners ask us why the plants do not look the same as when the site was installed years ago. Tall plants meant for the back have moved to the front, blocking smaller plants from view. Plants meant to stay in neat clumps have spread and intermingled with other plants throughout the restoration.  Some plants have simply disappeared and others have taken their place. Why does this happen?  There are multiple reasons why plants in their restoration are changing.



 Tall plants have migrated to the front, blocking view of shorter species.


Often times a restoration with both prairie grasses and flowers will, over time, favor grasses. In shoreline restorations as well, given certain site conditions, sedges and grasses can start encroaching into upland areas where they weren't intended.  Lake sedge and Canada Blue Joint are examples of sedges and grasses that might migrate on a site.

Plants can also migrate because site conditions can  change from year to year. This year there were a few storms that took down trees near restorations all over the metro area. When the trees come down, that opens the site up to light that will have an effect on what plants grow best on that site.  Shade tolerant plants might be pushed out by new sun-loving plants taking advantage of the new light.  Moisture conditions can also change over time, especially on shoreline restorations.  Water levels can fluctuate based on drought conditions, affecting plants that require very wet conditions.  However this year, many sites have flooded due to more rain, causing some upland plants to die or new weeds to encroach on the restoration.

To keep a restoration looking more like it did when it was installed our maintenance crew sometimes has to control certain native plants as well as the non-native species. Some native plants come into a restoration on their own, and despite being native, can be very aggressive.  These natives include Canada Goldenrod, Brown Eyed Susan, Jewelweed, Ragweed, and many others.

Once again these changes and their causes vary from site to site. Some plants that are aggressive and taking over in one restoration will be perfectly well behaved in another.  A plant that did well in similar conditions at one site might not necessarily do as well in another because of soil or moisture conditions. Depending on how landscaped a look is preferred, native plants will need to be controlled and new flowers will need to be planted to ensure there are beautiful blooms year after year.
