<p><font face="Helvetica, Arial, sans-serif">Hi Colleen,<br>
<br>
I don't have personal experience with growing Lolium multiflorum
(aka Lolium perenne ssp. multiflorum and Festuca perennis), but
I do get concerned when people talk about using it because it
has been mentioned as invasive or naturalizing by various
sources. Here's a sampling of links:<br>

Hi all,</div>
<div style="font-family:Calibri,Arial,Helvetica,sans-serif;font-size:12pt;color:rgb(0,0,0)">
I'm looking at doing a warm/cool season grass mix from Ernst in
an area that has a lot of exposed soil (we're very worried about
erosion). The mixes have annual ryegrass (<i>Lolium multiflorum</i>)
which is not native, but apparently germinates much faster and
more aggressively than the native ryegrasses. <br>

Does anyone have experience with these? Will the ryegrass peter
out in a few years? Any need to worry about it taking over too
aggressively?</div>

I'm facing the tradeoff between need to stop erosion and desire
to go all-native. If the annual rye is not detrimental it would
be worth the faster germination.</div>
