Hydrophyllum virginianum (Virginia waterleaf)

Welcome to ChooseSustainable.org a blog about individual climate action. In this series of short posts I present a native plant to encourage everybody to abandon our traditional way of gardening (basically a continuous fight against nature) and engage in sustainable gardening practices that nurture the ecosystem, sustain wildlife and foster biodiversity. I show the plants in a garden setting to dispel the myths depicting them as weedy and unsuitable for gardens.

In this post I want to talk about a shade perennial, ideal for areas under trees: Hydrophyllum virginianum. The plant is a ground cover, only one foot tall and is ideal for shaded locations. It may become aggressive if it finds the right conditions filling up the entire area.

Quick facts:

  • Zones: 4-9
  • Bloom time: May, early June
  • Sun: Part-shade, shade
  • Soil Moisture: Wet, moist, well drained. Rich soil is preferred.
  • Aggressive: MODERATE; It does spread if it finds the right conditions
  • Front yard: YES
  • Height: 1-2 feet max
  • Status: OK.
  • Maintenance: LOW
  • Wildlife value: LIMITED

Wildlife connection: The plant is an early bloomer and as such is important for bees, bumblebees, and other small insects early in the season.

I planted this plant because I was looking for an aggressive ground cover in an area that was in partial shade. Unfortunately the chosen location wasn’t the right one because of the poor soil, insufficient soil moisture, and probably excessive afternoon sun in summer. In spite of the non-ideal location the plant has expanded and covered a large part of the intended area. It is easy to transplant, so last fall I decided to move some of the plant to a more suitable location and I am expecting a much better outcome.

Based on my mistakes I can say that the plant is extremely resilient and it will manage even in conditions that are not ideal. Depending soil and sun, it may suffer during extended early-summer drought and may need occasional watering. The plant makes a great ground cover/first layer reducing your weeding activity substantially.

Virginia waterleaf emerges in April, when other perennials are still dormant, blooms in May, and the foliage persists until fall.

The foliage is dark green with characteristic small white discolored areas that my give the impression of water drops. The foliage is dense in springs, but it thins out at the end of summer. The compound leaves are made of 4-7 lobes as visible in the photo.

The bloom consists of clusters of small, bell-shaped light pink flowers that sometime they can take on a lavender shade. The clusters are large enough that they are noticeable. The flowers last for one or two weeks before releasing a large amount of seeds.

The importance of ground covers

I take this opportunity to talk about the importance of ground covers in your native garden. Over the years I have experimented with several non-chemical weed management techniques. So far, the only truly successful way that I have been able to reduce or eliminate the need for weeding has been through ground covers and dense planting. Virginia waterleaf is one to try. In my next post I’ll talk more about this topic and discuss great tested ground covers for sun and shade.

Every native plant you add brings back a piece of ecosystem that is vital to biodiversity.

Trash to treasure: Winter gardening in your native prairie

Welcome to ChooseSustainable.org a blog about individual climate action. In this post I talk about winter gardening in your native prairie. Have you given a thought about transitioning your gardening habits from an endless list of “getting rid of” to welcoming, sustaining, and restoring of lost habitat? Do you know that restoring a piece of native ecosystem in your backyard is one of the most effective ways you can fight soil degradation, pollution, and loss of biodiversity?

In this post I talk about winter activities that help biodiversity. Remember that wildlife, just like us, inhabits the land all year round, not just in summer, and needs food, water, and shelter all year, just like we do. The good news is that when it comes to winter gardening less is more. In fact, our obsession with fall cleaning deprives other species of their winter shelter and eliminates important sources of food for birds that don’t migrate. Let’s get started then with our fall and winter trash to treasure list.

Leaves

Trash to us treasure to...Birds, insects, turtles, moths butterflies, fireflies, bumblebees, chipmunks, frogs and other amphibians…and the list goes on. Don’t trash the fallen leaves, gently push them out of the lawn area and collect them in a designated corner of your yard. They appear to be a lot, but after a couple of rainfalls they reduce to little. You can also divide them among the planted areas and around trees. I add to them all that is produced in the kitchen, mostly fruit and vegetable peels, and coffee grounds.

Leaves can stay were they fall on planted areas
…Or they can be collected in one place for leaf compost

perennial STEMS

Trash to us treasure to...stem nesting bees, birds, rabbits, chipmunks. Perennials should be left as they are. Perennials in winter provide food and hiding places for birds and small animals. The stems of perennial plants that we are quick to remove because “dead” and “unsightly” provide nesting space for stem nesting bees in early spring. They should be left untouched until late February or March, then just shortened to about 1 foot. You can leave the cut ends on the ground as they quickly decompose during spring and summer and enrich the soil beneath. In early spring stem nesting bees lay their eggs into the hollow stems where the new larvae develop. Read more about stem nesting bees here:

Beautiful perennials that provide good nesting for stem bees are: Elderberry, Joe Pye Weed, Goldenrods, Bee Balm, and Purple Coneflower.

Long perennial stems provide hiding for birds while they search for insects under the leaves
Bee balm seed heads are a source of food for winter birds. In early spring stems can be shortened to 1 foot to provide nesting space for native bees

SNAGS, branches, and twigs

Trash to us treasure to...Birds, bees, chipmunks, lizards, rabbits, squirrels. Our fall and winter cleaning often includes complete removal of fallen branches, twigs, and dead trees. Trees continue to live after they die. Hollow wood provides nesting places for wood nesting bees, birds, and small mammals. If you are lucky enough to have a wooded area in you backyard, you can leave dead trees (snags) properly shortened to avoid hazards, branches, and small piles of wood material. Dead trees at the edge of a backyard can also be kept and just cut back enough so that they are not hazardous. Fallen twigs and smaller branches can be piled up in a corner and left there to decompose. Here is a link to know more about wood nesting bees and nesting for pollinators:

Wood mushrooms decompose the hard part of the wood releasing nutrients that enrich the soil. Keeping snags and branches as much as we can ensures that the full cycle of life takes place in our yard.

Small brush piles are used as winter shelter
Empty logs are used by bees and other wildlife
I love to watch mushrooms grow on the stumps of trees

LAWN imperfections

Trash to us treasure to...Ground nesting bees, bumblebees, chipmunks to name a few. Small holes in flowerbeds and lawns are likely due to wildlife trying to find a place to overwinter. Ground nesting bees can dig their own holes where the soil is soft, or they can also reuse holes dug by other wildlife. Extensive pesticide use on the lawn and obsession with lawn appearance are harmful to everybody and especially ground nesting bees. Read more here:

A small hole in the lawn can be used by ground nesting bees or other wildlife as winter refuge.

enjoy winter gardening

Finally, fall and winter gardening is a lot about observing, discovering, and planning for spring. Already in February we’ll be planning our cutting and sowing if we haven’t done it in late fall. Sustainable fall and winter activities ensure that life continues in your yard through the seasons and allow wildlife to survive harsh winters. HAPPY SOLSTICE DAY!
