Sedges have Edges...

A recent post on an alternative use for grass elicited a great response from a reader about alternative lawns. As I've said before I'm not a big fan of grass, but I know there are reasons to maintain these open spaces - family recreation, picnic spots, pets, etc. - that look a little more traditional. Buffalo grass and members of the sedge family are two options that come to mind almost immediately as viable alternatives.

Sedges look like grass, but are not. In the woods they often look like a wispy version of lawn grass, but upon closer inspection they have an edge. Literally. If you've ever pulled a piece of grass, you'll notice that the base stem is round with a hole. A sedge is not round, but has an edge. A good friend reminded me of this little ditty: Sedges have edges, rushes are round, and grasses, like a--es, have holes. A native plant unlike traditional lawn grasses, sedges have a deeper root system, can be deer repellent, and relatively drought resistant. David Mindell at PlantWise, a friend as well as a restoration and native plant expert, suggested Pennsylvania sedge as a good option. "It tolerates light shade, some traffic, and dry conditions. It's beautiful, never needs mowing, and can be established with plugs or seeds."

Buffalo Grass
Buffalo grass is a grass, but a native one in the western prairies that works well for grazing. With roots that can reach five feet down it is terrifically drought tolerant and great for stabilizing soils, and is especially happy in sandy, well-drained spots. According to David Mindell at PlantWise, he's used it on the west side of the state with great success.

Useful Information Sources
Planting and Maintaining a Buffalo Grass Lawn by Terrance P. Riordan
This book from the Brooklyn Botanical Gardens on installing and maintaining a buffalo grass lawn looks quite promising and helpful. The page itself about the book clarified a great deal for me, and offered further inspiration.

Sedge Lawns for Every Landscape by John Greenlee
Another great book from the Brooklyn Botanical Gardens this one offers a number of good suggestions about sedges and using them as an alternative to grass.

Michigan Wildflower Farm
A local source for alternative lawn mixes using seeds from Michigan natives. David has used some of these at different sites with good success. The site also offers valuable information to get you started with native plants.

Wild Ones
Another great resource for learning about native plants and how and why to incorporate them.

When I was 12 to 13, I was on a bog tour on Beaver Island, MI. A CMU biologist was leading the tour and I as easily the youngest person there. I'm pretty sure he didn't expect there to be any youngins there, because he told the saying slightly differently:

"Sedges have edges, reeds are round, and grasses, like a--es, have holes."

Of course, after saying this he looked up at my mom and me and blushed. But she just said, "oh, don't worry!"

I learned the same sedge/grass/rush saying in a spring plants class at UofM. It's just too catchy!

Thanks for rounding up this information! I'm going to look into the sedge lawns more and maybe try it in some areas.

I've heard it said, "Sedges have edges, rushes are round, grasses we smoke when the cops aren't around." Of course, that's not as helpful for IDing purposes. :)
Oh my, Jackie! :) I'd never heard that one before! Thanks for sharing that, and for reading.

Finding Heirloom Seeds in Japan

Drying pods of heirloom Hutterite Soup Beans. Since moving to Japan eight years ago, one of my greatest challenges as a farmer-gardener has been to find heirloom or open-pollinated seeds. The majority of seeds available are not GMO (genetically modified organisms) as Japan, at this point, doesn't accept this material. Most seeds, though, are nearly all F1 varieties. Heirloom and F1 Varieties In plant breeding, F1 is the name given to the first generation of a cross between two true breeding parents. For example, if I decide to cross an Amish Paste Tomato with another heirloom variety tomato such as Emmy, in hopes of getting a gold paste tomato, the resulting generation of fruit is F1. In order to get that tomato of my culinary dreams, I'll need to choose members of that first generation that are headed in a direction I like - early ripening, medium-sized fruit, good taste - and save their seeds. I'll plant them and repeat the process again and again over time unti

Satoimo: One of Japan's Favorite Slimy Things

Satoimo in all their hairy glory. This post first appeared in slightly different form on Garden to Table as part of the 2012  Blogathon . The website has since moved on to the ether, but the post is still a good one. After all, people here are still eating satoimo on a daily basis, and many others are just seeing these little potato-like objects for the first time. Enjoy! Satoimo is one of Japan's odder vegetables. Under it's rough, slightly furry skin is white flesh that is a little bit slimy even raw, and with a gentle nutty flavor.* Baked, grilled, steamed with dashi, or deep-fried satoimo stands well on its own or paired up with other vegetables and meats in a wide variety of soups and stews . (The leaves are also edible.) Satoimo stores well, and like any root crop worth the effort, stocks are just running low on this household favorite as the farmers in my area of Tokyo get ready to put a new crop in the ground in May. I cannot say I was a fan of this l

Goma Ai Shingiku - Sesame and Chrysanthemum Greens

Last week I had the pleasure of helping some friends work in their parents garden not too far away. Tucked behind the house, the garden sits on a former house lot. When it came up for sale about five years ago, my friend's father jumped at the chance. Open land in Tokyo can be hard to find and expensive, but for a retired professional looking for a little spot to till in the city it was an opportunity to good to pass up. Now, it is a garden to envy. As we came through the gate rose, lily, and peony blooms greeted us with great shouts of color while rows of vegetables stood tidily at attention on the sunny center stage. Small fruit trees along with one of the biggest sansho trees I've seen yet stood quietly here and there. Near waist-high sweet corn, bushy young potato plants, cherry tomatoes, eggplants, and beans were preparing their summer fruits, while a handful of still quite luscious looking winter vegetables like komatsuna, mizuna, and kabu held one last ro
