Thistle....help me remember
Comments (7)I'm using Blessed Thistle, which is an annual here, I believe. It's kind of a pretty thistle, actually. Cnicus benedictus is the latin name for this plant. I'm also using St. Mary's or Milk Thistle (silybum marianum), which is a very pretty thistle. The basal growth of rosette foliage is green mottled white. The blooms are large pink, artichoke type blooms. We'll see what happens. Seems like I've planted almost everything I can think of to attract the ladies! How particular can they be? LOL!

Comments (2)Hi, Thanks for the tips! I thought I was doing the birds a favor by leaving a few canadian thistles for them to eat. The thistles (a few) were intermingled w/ rasberries. I had considered it my "Wildlife Sanctuary". The birds came in flocks for the thistle seed. I will be getting rid of all. It spreads like wild fire and is difficult to keep up with. A huge patch sprouted up 200 yards away. In one season it covered an area 50 square yards. It was so thick the deer used for a bedroom and cover....See Morecomposting weeds
Comments (1)I'm a little reluctant to say this because it COULD come back and cause trouble for you, Bob, but I have very little concern about what roots I put in the compost pile. First let me qualify that by saying roots not seeds. Weeds that have gone to seed go in the trash can. And, secondly, altho' I've got thistle problems, they aren't Canadian. It's the Italian thistles sneaking out of the neighbor's raspberry patch that end up in the vegetable garden. I don't think that they are GREATLY different in the tenacity of the roots but I could be wrong. Even, dare I say, quack grass roots go in the compost as long as it is early in the season and I know that they are going to be buried under a few feet of material over a long period of time. And by long period of time, I mean 18 months or longer. You see, I make use of one season's compost while the other one sits. I remove weeds that show up on top of that pile but otherwise it just composts from the end of one growing season (about October) until it is utilized in April or May (18-19 months down the road). WhatÂs on the very bottom of that pile has been there for 2 years. Besides plant material from the garden, IÂm adding every peeling from the kitchen, manure, and garden soil as the first season rolls along. No, I'm not trying to compost in any "hot" fashion. Seedlings will show up when it's used, usually squash and pumpkin but not much else. It's a method (among others) that I have used for a good 10 years but tenacious roots need to buried deep and any plants that show up on the surface of the pile during those 18 months must to be pulled.

Comments (5)Thank-you for your input! We have zebra swallowtails that go for the paw paws and spicebush swallowtails that go for the spicebushes and a scattering of the tiger swallowtails that seem ok w/the dogbane and another plant whose name escapes me but there were literally clouds of tigers when the thistle was everywhere....hoping to bring them back so I will get some Zizia seeds and try some C. discolor. We are overrun w/tulip poplars (my 8 yr old calls them tulip populars :) and I have a weakness for sassafras...though they don't seem to live very long around here. I will carry on the war against C. arvense...I shall not give in to tiger swallowtail temptation!...See Morefroggy
