End of November: What is a Novice Forager to Do?

This is in response to a question about the seasonal changes in foraging,what is available?.  It will also be a short sketch of what is out there along Cloverlea and Rolandvue.  The summary at least at the foraging 101 level is --not much.  You would need to be both hunter and gatherer.  And fire-builder.  The little remaining food out there would need proper cooking to break down the cell walls, aid digestion.  If you can't build a fire your plant identifications will be mostly worthless.

There is still a lot of green.  I will not picture the dandelions, plantain, and dock.  They are still there and probably still useful in emergencies. Most references suggest the early leaves, particularly in the spring.  In the fall there is a tendency for the nutrients to concentrate more in the roots, there is not much science on the nourishment left in the fall greens.  There is the wild onion/garlic which will be there most of the winter.  With softer soils they can be pulled, may require digging to get the small white bulbs.  This would be a little support and prevent scurvy.   Greater celandine is still up, has some medicinal uses but a toxic orange sap, creeping charlie is green and probably safe.  Next to the wood poppy(celandine) was winter creeper.  This is a newly noticed invasive vine also not popular as a forage.

There does not seem to be good use for the holly. The birds can eat the holly berries and us apex predators eat the birds.  Ivy is also not generally suggested as forage although V mentioned that it can be an animal feed when necessary, not a preference.  The arbor vitae can provide a tea with vitamins but not much calories.  Most of the invasive vines have died back, the kudzu and the porcelain berry. The acorn crop seems light this year, it does go in cycles, and acorns take almost as much energy to prepare as they yield in form of food.  It would be better to let the feral pigs eat the acorns and the beechnuts, then enjoy a luau.  But I have not seen many pigs eating the mast at the end of Wagner Road.

You could chew on the twigs of the spice bush, corner of Cloverlea and Rolandvue, to assuage the hunger pangs.  I can imagine the ancients approaching the winter solstice with a feeling of unease.

Wild garlic,species of onion,allium oleraceum, present most of winter

Garlic mustard, looks healthy,same smell and taste, some vitamins?

Greater celandine,toxic, some herbal uses when properly prepared

probably mock strawberries, leaves edible, variable GI effects

Ground ivy, edible in moderate quantities,should be creeping, attached at nodes, mint family

Arbor Vitae, tea of terminal leaves can supplement vitamins.

A lot of holly with berries but not forgeable 

Also a lot of Poke Salad, looks tempting but poisonous.

Deeper in the Weeds: Feverfew vs Chrysanthemum

We found an interesting plant in the woods a few yards off Rolandvue, no where near a garden which looked like some of the images of feverfew.  When the botanists looked at it the first impression was a garden variety (escapee) chrysanthemum.  Now a former name for feverfew was Chrysanthemum parthenium so the distinction could be considered minor.  The latin now is Tanacetum parthenium.  This post will raise more questions than it will have answers.   Ultimately are you interested in these microscopic characteristics, or happy with the general title of chrysanthemum?  What does this imply for the medical and chemical qualities of the the various plants?  What about the use as foraging? There may not be true science as yet.  We will illustrate some of the fine characteristics that would be needed for a final opinion with the detailed dichotomous keys.

We had a garden chrysanthemum for comparison, but again there is uncertainty.  There are many cultivars of the garden flower and some possible hybrids in the woodland flower.  The true central flowers appear some what different the garden flower being concave and the woodland flower convex.  This could be a different stage in maturity.  The inferior calyx is different with the longer tighter green sepals on the woodland flower.  After a detailed dichotomous key analysis the woodland plant did seem to be more like the feverfew than the cultivated plant.

There is little science behind using feverfew for actual fevers, but it has been used as a treatment for migraine. the active agent is parthenolide.  The cultured varieties also have chemical activity ,an insecticide with the active agent being pyrethrin.  There is no clear analysis of which variety has the medical benefit, which has the insecticide or how the two merge into one another. The commercial interest focus on either migraine or the insect repellant not both, and they may be totally separate.

If you do get interested in the magnified appearance or even microscopic appearance there are many variations to learn.  It is not clear which if any correlate with the chemistry of the plant.  If the cup is smooth rather than rough is it therapeutic or not?
