I am going to have to keep my eye out next year. The goldenrod and ragweed get so high....I have no idea what goes on behind them late summer. Allium, huh? I hope it's a pretty one. :-) The dried seedheads are pretty nevertheless. Thanks, Saltcedar!

A case has been made for a point of view that is popular in some circles. The end of the world is not nigh if a few more Dames Rocket plants are grown in the state of Iowa. To be sure, there are specific locations where DR may never present a problem. On the other hand, there are places in Iowa where it is easy to see why so many states have declared DR to be a thug and have placed it on their noxious, invasive species lists. The native/non-native, invasive/non-invasive discussion is a complicated, many-faceted subject. Oftentimes the subject knowledge of any given plant contains larger areas of grey than absolute black and white. Frequently, what we thought to be true later turns out to be terribly flawed and near sighted. We wind-up ruing decisions drawn from previous naïveté. For example: Kudzu will never become a problem up here in the north because it will never survive our winters. Yet, it has been found merrily growing away at locations in both the Quad City and Chicago areas. It has been perhaps 30 years since the introduction of the Bradford, Callery pear tree. One of the widely-touted attributes of this admittedly beautiful tree was the fact that it was also sterile. However, there are now confirmed reports of scattered infestations of this "sterile", non-native tree forming mono-cultures in natural areas, which are displacing the native plant populations. http://www.inmygarden.org/archives/2005/12/callery_pear_tr.html Confirmed reports of scattered infestations of the "harmless" Norway Maple forming mono-cultures in natural areas and displacing the native plant populations have been made in the Iowa City area. I dont think that we need to elaborate upon the natural devastation wreaked upon our state by Purple Loosestrife (Lythrum salicaria) and its allegedly "sterile" cultivars. The arguments, both pro and con, can go on forever with each side citing contradicting "facts" which trump equally contradicting "facts" from the opposing view. The point is that many of these problem plants dont seem to reveal their truly ugly side for a number of years until it is too late. One guiding principle that I personally use is that if a plant is a problem plant in other domains, it brings with it a very likely potential for problems in my domain. Entrusting government bodies to act responsively within a timely period seems less than prudent to me. I have little abiding faith in the assurances of the "experts". Good intentions sometimes go wrong. After all, it has been estimated that over 75% of the exotic species now residing on the various invasive species lists were, in fact, originally introduced by the very same institutions now declaring them as invasive. Invasives like kudzu and crown vetch are but two examples. Does Dames Rocket also fit into this category of intentional (albeit, well-intentioned) introduction of invasives? It certainly does in many other states. As with so many things in life, it comes down to a matter of personal choice. Is DR destined to become a thug throughout our fine state? Quite frankly, I dont know. It may eventually prove to be as harmless as a babys burp. However, what I do know is that we all have a choice whether to plant potentially invasive plants or not. Personally, with the vast selection of so many other wonderful plants available to each and every one of us, I see little incentive to make that choice. Suffice it to say that I believe each of us should continue to raise our standards as we continue to grow as gardeners. Have I grown DR in the past? Admittedly, the answer is yes. However, I discontinued that practice over ten years ago, after I was on the receiving end of some "enlightened admonishment". After some cursory investigation, I saw the light and pulled the plants. I wound up selecting other plants that actually offered superior performance. As I continue to garden, I continue to correct past mistakes. Concerted efforts are made to educate myself to "both sides" of issues gardening related or not. In the end, I am again left to make a choice. Although there are often many selections to choose from, I am behooved to select the best choice with a potential to produce the most collective good. I encourage others to do so as well. IronBelly

pf, if you follow the link provided above, there seem to be a good number of people who have had problems with you. I did not mean to imply you shouldn't be traded with. All I meant to say was that if someone wanted to trade with you, but were leery of doing so, they could ask you to send your end of a trade first, and then go from there. If you have issues with someone trying to help you AND a potential trader, well, that's just sad and says a lot.

It dances in, hangs around for 2 or 3 years, and then moves on. It was at the edge of the woods, now its gone, but in a nearby vacant lot, with disturbed subsoil, it was all over the place this spring,- we had sustained, algid killing, cold. Seeing a lot of it, on disturbed soil, has probably worried people enough to put it on the invasives list. We brought some home when I was a kid, because it was pretty and smelled lovely. It only lasted about 4 years with occasional hand reseeding. It didn't last in the vacant lot we took it from either [zone 7]. If you don't wan't it seeding, you can snip off the seeds, It is hard to pull up - why bother, you can clip it short. It may not have liked the cat [sand] box dumped there either. It's a short lived perennial and won't take over. Maybe it's worse in cold zones. It survives to zone 3, and there are fewer species up north. The Wisconson site, lists it as invasive, and said that this plant was introduced in the 1600s. Compared to many weeds, down here, it's not that bad. Please mention if you've seen a sustained problem, especially in zones colder than 6. It seemed someone on another thread/forum, in Pennsylvania, said it didn't last, there either. WoW ! I never heard of stilt grass before, but there is a little of it ! Guess I'll have to go after it, to slow the onslaught. It would be great if civic groups could be educated and mobilized to go after invasives, especially together with younger groups, like scouts. Here is a link that might be useful: dames rocket
