Gardeners' Notes:


On Aug 14, 2018, Cmf1864 from Cortland, NY wrote:

I made a memorial garden under a tree for my father who recently passed away. I planted orange cosmos, nasturtiums, moss roses, orange marigolds and white alyssum. My father ate nothing but orange popsicles before he passed away. So I was very surprised to find this little surprise growing in front of my flowers. I looked it up to see what it was. It gets morning shade and fullon very hot afternoon sun and has grown so much without being invasive to my other flowers. It may be a weed but I love it for its tiny orange flowers. Maybe a tiny gift from above that fits in perfectly. I will be collecting the seeds and replant in other areas next year. I live in Cortland, New York. I am wondering if it is possible to plant inside if it would grow all year long? Thank you.

It is a pretty little weed from Europe that is commonly found in the East and Midwestern US and other parts of North America. I usually don't find it to be a horrible plant, just some here and there. It is easy to pull out. In some spots it can be a powerful prostrate weed. This annual is a common invader of gardens, lawns, and waste places. In England it is also called "Poor Man's Weather-glass because the flowers close before it rains; also called Red Chickweed. Its many tiny seeds are borne in a globular capsule that splits open in the middle. It is a member of the Primrose Family.

We find it here
We find it there
Us gardeners find it everywhere
Is is from Heaven
No it's from Hell
That damned invasive Pimpernel!

I found this plant growing in an area where new houses were being constructed nearby, brought it home, planted it in a pot, and collected the seeds once they dried. . . .

Then, I cast them in a semi-shady spot. It has grown & had flowers & seeds every year since (about 5?), but is not invasive here, perhaps because our soil is heavy clay, and it supposedly prefers a light soil.

I most definitely enjoy the laciness of this plant's growth habits, the small leaves and the delicate, plain, flowers!


On Jun 29, 2012, Emma60 from Grassy Creek, NC (Zone 6a) wrote:

This is one of the prettiest, most welcome little flowers I know of. I discovered it growing on a neighboring property many years ago and dug it up and put it in my garden. It stayed in the same spot (or its seedlings, perhaps) for several years. It never reseeded anywhere else, so invasive is the last word I have for it, and since I didn't have nearly enough in my garden, I would say "evasive" is more like it.

This plant is pretty for a weed; however, it is rampant in my garden and it is poisonous if ingested by animals.

For a 'weed' -- it's very lovely. Comes up unbidden. If unwelcome -- uproots easily enough. The blooms' coloring is quite attractive...even enviable.

Cute little flowers for a weed & has spots on the undersides of the leaves. Not too invasive so I leave a few to bloom around the garden. It is a few zones hardier than listed

I've had this coming up in a small area of my garden for a few years now. I don't find it invasive at all....It just stays and reseeds in the same spot every year growing between the other plants. Little orange/red flowers with a bluish eye.
I hope it comes up again this year!

One or two are great, but it's very invasive. Am forever pulling it.

In climates where it is not hardy, scarlet pimpernel reliably reseeds to become a permanent member of the garden. Seeds sprout without assistance, and are easily thinned.

A prostrate, variable annual from Europe but widely naturalised across the Northern Hemishpere.

Has ovate or lanceolate, mid green leaves on prostrate stems. Bears 5 petalled, solitary flowers which are normally a brick/orange red but can be blue, white or a pinkish shade. It may also have a purple, pink or blue eye.

Flowers anywhere between March-October and for many months at a time. They close on rainy days and dull days or at 2pm

Likes a moist, well drained soil in full sun but will tolerate a little shade. Being small it prefers not to have much in the way of taller competition. It grows well in a container or as part of a sunny rock garden.

It was considered an anti-witchcraft plant and was used to remove splinters put ... read more
