The picture you included isn't Knotweed, it looks like what the original poster had which is probably Solanum nigrum. It's a weed but I wouldn't call it 'serious'. It certainly won't take over an area the way Knotweed does. And it's a lot smaller. You can just pull it if you don't want it. WW

Noisette roses rock! I was thrilled that out of the seven plants of 'Cato's Clusters' I grew from cuttings in 2004, one sported a cane that produces only white blossoms, and now 2/3rds of the plant now (in 2012)sports pure white blooms from the moment that the sepals part. Other canes have c. 50% pink blooms and the rest pure white. Nearly all Noisettes where I live are highly disease resistant in 3 local no-spray gardens. (Mac being a notable exception because she's often covered with p.m.) I also grow -Celine Forestier -Marechal Niel -Mme. Alfred Carriere -Lamarque (along with Crepescule the most resistant to p.m., here) -Le Pactole -Reve d'Or' I love that rounded bloom form, it is such a romantic bloom style. -'Nastarana' I have two of these pretty white Noisette roses flanking the entrance to my most fragrant rose garden, their scent, like R. moschata, wafts on the air filling it with Musk rose scent for a distance of several yards. Of all the Noisettes I've seen and smelled at the Vintage gardens collection and San Jose Heritage Rose garden the most strongly fragrant to me, and the one I desire most,is 'Secret Garden Noisette' which has red-pink staining on the outer edges of the petals. I ruffled a few blooms on the plant, and my hand was perfumed for several hours afterwards. 'Secret Garden Noisette' was found in the same garden as Secret Garden Climbing Musk' I think Rogue valley sells it. It is one of the roses I loose sleep over, lusting after. Luxrosa

Jill, I'm so glad that Malissa came out to help you. I became interested in Missouri natives in 1986. I was an hourly employee for MDC and a forester (now retired) was pretty knowledgeable about native plants which peaked my interest. I bought a copy of Denison's "Missouri Wildflowers" and became absolutely addicted. In 1987 I moved here and was able to observe a lot of plants in their natural setting. We have 40 acres in some pretty rugged Ozark deep draws and dry ridges. It's oak/hickory forests and is extremely rocky (car size boulders). I started growing natives and learning about seed collecting, etc. Over the years, we've noticed that our dry ridge with its accompanying draws has become more lush, the soil is better and the increase in species of birds is amazing. Along the way, I've had a lot of support from professionals at MDC. For the most part, these people are doing what they love and are dedicated to the resource. This forum is a great source of knowledge for natives. Somebody here knows the answer to about any question you might have. Keep in touch about your place and have fun!

Is this indeed paperwhite? It looks tall in the photo....I'd say the ball of flowers is at least 12" from the ground. Yes, it is blooming now, at my mom's home in Boston. (Finally got picture to upload using FF. Before I was using IE.)
