Ugly weeds of summer: prostrate knotweed

Prostrate knotweed (Polygonum aviculare) Prostrate knotweed is a summer annual that grows in hard, compacted soil near footpaths and gate entrances. It emerges early for a summer annual, more than a month before crabgrass, a fellow summer ugly, makes its appearance. New sprouts of prostrate… Continue Reading “Ugly weeds of summer: prostrate knotweed”

Weed early and often: creeping buttercup

Creeping buttercup (Ranunculus repens). When creeping buttercups first appeared in my garden, I was inclined to think positively about them. After all, they seemed preferable to pachysandra, which I detest, as a ground cover. I thought they might be hardy geraniums until the yellow… Continue Reading “Weed early and often: creeping buttercup”

Larval food plants for great spangled fritillary and common buckeye butterflies

A great spangled fritillary (Speyeria cybele) and a common buckeye (Junonia coenia) were seen in my garden in the fall of 2017. September 22 for the great spangled fritillary. October 19 for the common buckeye.   October 19 was also a day when clusters… Continue Reading “Larval food plants for great spangled fritillary and common buckeye butterflies”

Weeds of spring: purple deadnettle, henbit, common chickweed, and hairy bittercress

Weeds of spring, also known as winter annuals: purple deadnettle, henbit, common chickweed, and hairy bittercress. Last year, in the posts Purple deadnettle, or is it henbit, and Weed report 2016, I fessed up to misidentifying purple deadnettle as henbit and wondering if any henbit was… Continue Reading “Weeds of spring: purple deadnettle, henbit, common chickweed, and hairy bittercress”

Weed report 2016

Weed report for 2016. Lovely photo above of crocus blooming on March 11, when you would think that the garden is weed-free, at least visibly so, but just look in the upper righthand corner. Creeping Charlie. In March. At least it isn’t growing. This… Continue Reading “Weed report 2016”

Common blue violets–wildflowers or weeds

Common blue violets (Viola papilionacea) are wildflowers or weeds, depending on your perspective. In the introduction to William Robinson’s The Wild Garden, Expanded Edition, Rick Darke distinguishes wildflowers from weeds by writing that wildflowers are usually perceived as pretty and innocuous. Wildflowers do no harm… Continue Reading “Common blue violets–wildflowers or weeds”

Purple deadnettle, or is it henbit: third winter annual to make a showing

December 2016 update: I think the winter annual I have been identifying as henbit (Lamium amplexicaule) may be purple deadnettle (Lamium purpureum) instead. Weeds of the Northeast calls purple deadnettle and henbit similar species. They describe the upper leaves and square stems of purple deadnettle… Continue Reading “Purple deadnettle, or is it henbit: third winter annual to make a showing”

Hairy bittercress has got to go

I am not so sanguine about hairy bittercress (Cardamine hirsute), seen above,  as I pretend to be about common chickweed. I can’t defeat chickweed because there’s too much of it. I think I still have a chance with hairy bittercress before it explodes its seeds… Continue Reading “Hairy bittercress has got to go”

Common chickweed–lots of it this spring

I decided to give common chickweed (Stellaria media), seen above, a big bad 10 in my weeding hierarchy this spring. It is big, thick, lush, and getting ready to bloom and go to seed simultaneously. According to a Penn State Extension fact sheet, each chickweed plant… Continue Reading “Common chickweed–lots of it this spring”

September renewal

September renewal. Since most of my life up to now has been spent observing a school calendar, September still seems like a time to start again, to make new resolutions, to get excited about stuff. So, while I still have the habit of thinking… Continue Reading “September renewal”
