vegetable garden with plastic mulch. I have several family members who use this stuff for their gardens and have great results. There is virtually no weeding.
As this relates to a prairie garden though I read eliminating everything from the site has to be done in order for most seeds to germinate, and for most seedlings to get through their first year.Another thing I've read is that turning the soil over (like I did) disrupts the seed bank and causes a mass germination of weeds. For both of these reasons I decided to lay down a wood mulch, and rather than using seeds I went with plugs.
, Agastache foeniculum, to go.
Come August the Showy Goldenrod, Solidago speciosa, started budding. Now I've herd two opinions about this plant. A source in Missouri from the Shaw Nature Preserve says this plant is down right thuggish, and loves to spread everywhere. The guy who maintains the prairie at the Mt. Cuba Center in Delaware says they've grown a few plants there right next to their meadow garden for years and it's never reseeded. So your local variety and how it reacts to your soil type may vary.
Things I planted but didn't get to see:
Lace Leaf Coreopsis - grew and flowered but not very well.
Stiff Coreopsis - grew but didn't flower. This plant reseeds freely and spreads by root suckers. They're not very big plants but can be a slight problem in mass.
Blue Star - Will probably get to big for this spot but we'll see what happens.
Blue False Indigo - Will probably get to big for this spot but we'll see what happens.
Purple Prairie Clover - Grew, but wildlife kept nibbling off the flower buds before any of them bloomed.
Ozark Coneflower - This went dormant right when I planted it. I'm not even sure they'll come back next year.
Orange Coneflower - which looks exactly like Black Eyed Susan. Supposedly it's longer lived.
Meadow Liatris - Well worth your money if you can grow them. One of the best Monarch nectar plants.
Aromatic Aster - More people should grow this for it's natural dome habit. As for the smell they're only slightly fragrant but it's nothing special.
