Hello,Is the Kochia that you are referring on the site http://www.ext.colostate.edu/ptlk/2124.html as an invasive weed as Kohia shown on the web site below?http://www.banggood.com/100-Kochia-Scoparia-Grass-Plants-Seeds-p-82371.html?currency=USD&utm_source=...or this https://www.etsy.com/listing/99080534/heirloom-1000-seeds-grass-burning-bush?utm_source=google&utm_m... ?I try to understand if the invasive weed that your site is referring to is different from what I see on the pictures at these web site.Please, clarify.And I also curious if the plants on the pictures are harmless for Colorado and can be planted in a garden. Thank you, MJ

your photo shows an annual known as Kochia scoparia trichophylla; common names include burning bush, fireweed, belvedere and summer cypress.

There appears to be some taxonomic or nomenclatural confusion with regard to summer cypress; you'll find it given more than one scientific name. But is is closely related to the weed also known as Kochia scoparia, one of the most common and abundant weeds in Colorado. It is known as kochia, poor man's alfalfa and railroad weed.

Is summer cypress harmless in CO?
Some seed companies warn that summer cypress can be invasive.
Suggest you initially try summer cypress on a small scale (3-4 plants only).
