Gardeners' Notes:

If you like the appearance of this tall, fine-textured perennial, you can safely grow the sterile cultivar 'Elegant Feather', which will not become a weed.

I love to hike in the wilderness areas and in a hurry one day I forgot my insect repellent and decided to take the risk. In a short amount of time my legs were covered in small ticks and as drowning men clutch as straws, I grabbed a handful of the closest thing available to scrape them off. I was so successful having used this "unknown to me then" plant to remove about ten thousand tiny seed-like ticks. It removed them and kept them off for the rest of the day. I don't remember even a mosquito spoiling my time after I used it. It didn't take long to identify the plant as dog fennel and having dug up a root ball I have my own patch going now since it does not grow close to me. I have noticed the hens will eat a little every now and then and my root ball has doubled in one years time... read more

These plants grow wild in local fields and I like them enough to propagate them on my property. It takes a few years to mature to 7' tall bushes with feathery dill-like foliage. I've seen Bumble Bees living inside the bushes. In the fall, they turn silvery in flower and they become pleasantly fragrant. It's very easy to transplant the volunteering seedling to where you want them to grow as well. I've never been worried about invasiveness as it is easy to pull them up if unwanted.

I had 1 plant grow in a pot with my corn plant, so I separated it and put it in a pot by itself and starting trying to find what it is because it grows fast and has and awesome leaf pattern. I saw a post that said it discourages insects and that the plant can be used on reptile and insect bites. I'm going to plant it around my fence as a natural border!

I don't understand a few things about the specifications you show, but let me just ask you about one set. How am I supposed to interpret your height chart? Is this just another way of saying that the height of this plant varies from 4' to 10'? That really doesn't narrow it down very much does it? The same applies to your hardiness figures. This is really incomprehensible to me.

very graceful native virginia plant, nice tall background plant, in my 15 acres of fields which i am very familiar with i've only found 4 plants growing, so here in good topsoil fields it's not being invasive.

I love this plant! In Kansas City it is not at all invasive. I do wish it had more staying seems to want to grow only 2 years here before it dies back completely. The 1st year in my garden it reached 7' tall and looked absolutely beautiful.

I love this plant. Years ago it showed up in my yard voluntarily and ever since it grew and grew and more seedlings every year everywhere. DG ID forum helped me to identify it. It makes quite a statement, because it grows very fast and tall (up to 7 feet) and looks gracious with it's fine soft leaves. I collect all the seedlings that pop up each year and plant them in containers. I also like the smell of the roots. If you don't want the seedlings, they are easily to pull out, but as a background plant in a nice flower bed, I would give it a chance.

This plant started showing up this year in my garden as a weed. I've been pulling it up when it's still small, but some have grown to about a foot & are more difficult to pull. They seem to love being in my landscape roses. Or maybe I don't get them when they're small in that bed since the roses have so many thorns.

It's not that hard to control... IF you mow land regularly. If not, it grows fast and gives you woody stems with feathery leaves and branches, and sort of a sticky feel to them...leave a stink on you (not acutely unpleasant, though I don't think I'd use it for incense) when you brush against them, more especially if you try to yank them up. You can get 6 foot stems in a few months in my climate if you don't mow. Roundup and such kill it nicely -- if you spray thoroughly; otherwise, especially in an established clump, enough root mass may survive to send up new stems. Digging up the whole clump in winter also works, but again it's easy to miss a bit. Mow, mow, mow and the grass might even choke it out for you; leave it alone and you soon get a patch of ground that's hard to walk throug... read more

I find that this plant which grew of its own accord is sort of pretty to look at.
In my zone7a it does not appear to be invasive, but the plants that are here have strong persistant roots that will thrive even if tilled.
I like the impressive size and am glad to finally have identified it through the identification forum on Davesgarden.

i understand that it is a noxious weed and invasive, however, i let a big stand of it grow in the fork of my driveway just to see what it would do. it's now september and it's 7' tall and quite dramatic. it has a breezy, lacy look and when it's done doing it's thing, we can mow it down. we certainly have not watered or fed or done anything to it and never will! debi

An interesting plant. Seems to invade borders between wooded areas and open fields. Here it is easily controlled by cultivation or mowing. A stand of it is quite showy at first frost, makes it look like a dusting of snow,

RUN FOR YOUR LIFE! Dog Fennel with take over your yard, your pasture, your neighbor's yard and the field down the street! Extremely hard to get rid of and spreads rapidly - and nothing seems to eat it.
