Squirrels eating the Norway Maple

I’ve had a love/hate relationship with the squirrels. While they are amusing to watch, they cause the most damage to the ‘cultivated’ parts of my landscape of any single creature in my backyard. They are constantly digging around new plants; they’ve dug up my single little huckleberry several times. I’ve been lucky in that they have not bothered my tulip or crocus bulbs, much.

Black Huckleberry in mid-April, has been dug up 2-3 times over 2 years.

On the positive side, I noted 3-4 years ago that I had fewer Norway maple seedlings to pull out of the lawn. Then that fall I saw the gray squirrels munching on the seeds, both in the lawn and in the rain gutters.  I understand that these seeds are not the first choice for the squirrels, but they are plentiful and easy to come by.

Then a couple of weeks ago I saw a squirrel eating the flowers off the Norway maple. This was a new one on me, but anything that reduces the seed production gets a gold star in my book. I did a little checking on the web and found an interesting post by Albert Burchsted,  Apparently gray squirrels prefer the green flowers of the Norway maple over the reddish flowers of the Silver and Red Maples. The squirrels also prune the branch tips from several maple species, including the Norway, to get a drink of the rising sap. This explains the number of broken branch tips scattered on the lawn.


One other ‘destructive’ activity attributed to the squirrels is the snipping off of tulip flowers. While I have not actually seen the squirrels doing this, rabbits and/or birds may also share the blame, they seem to be likely candidates. The tulip flowers are neatly cut off at the base, leaving a mostly intact bloom to wither away nearby. While I have not been able to find my original source, I was told a while back that the animal doing this was after the condensation that collects inside the flower cup and not the flower itself. This creates a compelling image of a squirrel drinking from a tulip ‘cup’, but I would really like to see some proof.

Who did this, and why????

I would appreciate hearing from anyone who has caught an animal, squirrel or otherwise, in the act of tulip vandalism.

Native Ground Covers

When it comes to landscaping around the home, many people seem to be more comfortable with a single carpet-like planting – grass, vinca, or pachysandra. This is more comforting, easier to ‘read’ and may be a representation of nature ‘controlled’.  In the natural world the ground cover layer is more likely to be a mix of species. Each species occupies a preferred niche in both time and space. Hayscented fern is one of the few species that I’ve seen that can really appears to dominate a space, but that was in a recently cleared forest. On closer examination other species were present at ground level. With time a more diverse community will develop.

In designing a ground cover planting with native species you should draw on a palette of low-growing plants that can work together and are appropriate to the site conditions. While the following list is not exhaustive, these are some of the natives that I have grown around my home that work well as ground covers.



Black Huckleberry, Gaylassacia baccata, is and evergreen woody subshrub that is found in upland woods and handles a range of soil moistures, wet to dry, and sun exposures light shade to full sun. It grows 1-2’ tall and twice as wide. I was impressed by the glossy green (and a few bright red) leaves in February. The flowers develop slowly through the spring and are just now opening. I’m looking forward to larger plants so that I can see these colorful flowers without bending over so much. Although slow growing, I have been able to grow this plant in a variety of difficult locations. This plant is becoming more available in the retail trade. Other huckleberries, preferring moister conditions, are also available.

3-Toothed Cinquefoil, Sibbaldiopsis tridentata, (formerly of the genus Potentilla) is another tough plant for tough conditions. I’ve seen this growing at the top of Cadillac Mountain in Acadia National Park. I’ve had a good experience growing this plant in a variety of challenging locations, such as on the edge of yew bushes. With a little protection it is evergreen through the winter and it produces clusters of white flowers in summer. While it can form a dense mat, it is not so thick as to exclude other plant from growing with it.


Bearberry, Arctostaphylos uva-ursi , grows under what would be considered very harsh conditions, but is must have very well drained soil to survive. While I’ve encountered it growing out of cracks in boulders on a hiking trail, I haven’t had much luck with this plant on my ‘typical’ residential site (too moisture retentive, my guess); therefore no photos, either.

Barren Strawberry, Waldsteinia fraganoidies, formes a fairly dense evergreen mat with good weed suppressive character. It produces yellow flowers in early spring (now in New England), but the fruit is inedible. In the photo it is growing with sensitive fern and Mayapple.  This native can be found at some nurseries, but its cousin, Siberian Barren Strawberry, Waldsteinia ternata, is much more available and is often sold under the same common name.

Hairy Alumroot, Heuchera villosa, has been a very effective ground cover for me in partly sunny locations. The collection shown here was grown from seed which produced a mixture of green and purple leaf forms. The leaves cast enough shade to control weed growth from below. Later in the summer it produces small white flowers on long racemes, but these are not particularly showy compared to many of the Heuchera cultivars.



Some other native plants that I have been trying around my home, which can be used in a ground cover mix, include Partridgeberry (Mitchella repens), Wintergreen (Gaultheria procumbens), Canada Mayflower (Maianthemum canadense) and Virginia Creeper (Parthenocissus quinquefolia) and a variety of ferns. There are many more native species that can be used as ground covers. Just take a walk in the woods to see what’s growing there. What other natives have you used as ground covers?
