 Maintenance Memo


Our maintenance crew is busy visiting prairies, shorelines, raingardens, and other native restorations all over the Metro area. What have they been observing? What natives are blooming first? What weeds are coming up this month?


Native plants love the rain we've received this spring,

Marsh Marigold
Caltha palustris

and now with a little sun they are growing strong and blooming with vibrant colors! A few examples of these early native plants are Marsh Marigold, Jacob's Ladder, and Wild Geranium. These are important plants for pollinators because they provide a food source early in the spring when other plants' flowers are still forming.


Jacob's Ladder
Polemonium reptans
Wild Geranium
Geranium maculatum


Non-native invasive plants also love the spring rain and are shooting up like rockets.  Our maintenance crew is busy spraying, hand weeding, and weed whipping them before they go to seed. Some weeds of biggest concern are Reed Canary Grass, Garlic Mustard, and Canada Thistle. 

Garlic Mustard
Alliaria petiolata

Spring is a great time to get a head start on managing these aggressive weeds because 

they are usually some of the first plants to come up. This makes it easier to spray the weeds and avoid favorable native species.  Dandelions or Creeping Charlie can also be annoying weeds this time of year but are a smaller priority compared to these weeds that can out-compete our beneficial natives.

Native Plant of the Month
Swamp Milkweed
Asclepias incarnata
Moisture: Wet or Moist
Exposure: Full Sun
Bloom: June- August
Color: Pink
Height: 3-4 ft.


Description: Clump-forming plant blooming in early to mid-summer with clusters of fragrant pink to mauve flowers.  Plant has a deep taproot, which makes it hard to transplant once established.  When bruised the plant oozes a milky sap.  After fertilization, a green pod develops; later releasing flat, brown seeds with tuffs of silky-white hairs for wind dispersal.  Grows in swamps, wet prairies, and ditches; although tolerant of well-drained soils in gardens.  Flowers, containing lots of nectar, are food plants for monarchs and other butterflies.  The plant serves as a larval plant for monarch larvae.  Other common names are marsh milkweed, red milkweed.

Invasive Plant of the Month

Yellow Rocket

Barbarea vulgaris


Exposure: Partial Shade/ Full Sun

Moisture: Moist or Dry

Height: 1-3 feet

Blooms: April-June


Description: A biennial from Eurasia, Yellow Rocket invades disturbed areas like road ditches and fields. The plant is in the mustard family and has small yellow flowers in clusters on the top of each stem, each with 4 petals.  The seeds are found in 1-2 inch pods oriented upwards on the stem. The leaves are lobed at the bottom of the plant but become smaller and more variable as they ascend up the stem. Multiple stems can come from the base of one plant. Management strategies include hand-pulling or spraying before the plant goes to seed.
