Offer: Various plants, you dig
I have many plants that self sow around our place. In the spring, there are usually plants in places I prefer them not to be. Often, I just have a lot of them and some can be dug out. Most of them are deer resistant, otherwise they would not have flourished so well.
Lamb's Ears, Rose Campion, Feverfew, Catnip, Lemon Balm (Melissa), Oregano (mild with big leaves, I use mostly in salads), Walking/Egyptian Onions (onion sets in fall or plants in spring or summer), Mint (naturalized and very hardy).
I have one good sized (12 - 18" diameter) Horehound plant that volunteered in my garden that is up for grabs. Not good to eat, but medicinally good for colds & coughs.
I planted red raspberries in my garden area. This was a mistake as they spread a lot and are now too big for my garden area. I plan to move them to somewhere else, but there are more plants than I will wanr to move. They grow well and are hardy, but need more water than I can give them to fruit well. They prefer a cool shady area.
