Rhodyman Thought I would post an update about my quest for R. eastmanii. Woodlanders was closed when I arrived to pick up an order, but they had left the plants near the potting shed, so I was able to pick them up. Left the question about R. eastmanii and received an answer yesterday. They are propagating the plant, but all are small now. They usually sell those in gal. size and should be ready later this year. Was a relief for me, since I checked with the RSF and found that packing & shipping charges was a KILLER! Maybe justified for an extremely rare species, that is nowhere else available, but I will have to wait on a local source, for this one. I'm pinching pennies right now, since the cost of necessities are rising at an alarming rate around here. Gasoline prices have risen 22¢/gal during past week and still rising! Thanks for your help!

Rhynchospora? Maybe a sedge? Here is a link that might be useful: You can search images here

If you are part of an educational institution I highly encourage you to pay a visit to the New England Wildflower Society in Framingham, MA. They are probably have one of the largest collections of rare native plants of the North East, and I'm sure you might be able to acquire some good species for your local collection from them. Also, their gardens are absolutely spectacular. Here is a link that might be useful: New England Wildflower Society

Found this question while on a different search. Long past the initial inquiry, but some ideas if you're still dealing with this. If the weed grasses are identified correctly, you could consider using Imazapic herbicide (Plateau, Panoramic, or a generic) at 4 to 8 ounces per acre for control with minimal damage to the desirable native wildflowers and grasses, and possibly none depending on what was in your planted mix and what rate you use. Use higher rates if there is a lot of growth or old plant litter. Use lower rates if the site has been cleaned of by burning. It can be applied both Pre-emergent (like right after a burn or mowing) or Post-emergent after the weeds are up, but works best if done early in the growing season before the weeds get too far along. Can be broadcast sprayed over the entire area or selectively sprayed with a wand to avoid application to desirable plants. Another herbicide that works well is Mesotrione, but best applied by selective spraying with a wand as it may cause more damage to some of the native wildflowers.
