<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>

invasiveness, but shown as exotic and growing uncultivated

</ul>
<p>Because of these and other sources, I've included <font

Mid-Atlantic Invaders Tool
(<a class="moz-txt-link-freetext" href="https://www.invasive.org/midatlantic/">https://www.invasive.org/midatlantic/</a>). Frankly, if I were
doing the planting, I'd choose to go all native.<br>

Hi all,</div>

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>
