I've seen 5 and 10 gallon mature Hakone grasses at local nurseries, but they are rare and expensive. You might ask a local nursery if they can special order them for you.

Not adapted to conditions on this side of the mountains. There was a garden form with yellow flowers being sold locally awhile back but it seems to have come and gone quickly. Possibly it was more tractable than usual. New introductions coming from one or a few suppliers may be dropped quickly for reasons other than the plant being hard to grow - I found the new cherry red tulip with the blue interior markings to be quite good yet despite special promotion with posters etc. by the introducer and supplier it too seems to have disappeared after only a few years. I've forgotten the cultivar name and when I have asked about it at local outlets (still buying from the same company) have gotten blank looks. It had a forgettable cultivar name like 'Spring Beauty' but you'd think considering the promotion it got and its unusual characteristics that it would have made more of an impression on someone working with it only a year or to beforehand.

Thank you both. It seems so late for Osmorhiza to be developing but that's probably what it is. I hadn't even thought of bellflower. I think you are both right.

Lawn#1- If spraying the crabgrass will potentially get some overspray on the freshly seeded area I wouldn't do it. The new tender shoots could easily be damaged by the herbicide. If you can spray the crabgrass without getting it on the new grass then by all means go for it. Lawn#2- On the fertilizer either way will be fine and IMO really won't make any difference. I would wait on putting down any lime as it could affect the fertilizer. You really don't want to put down both at the same time. It's best to wait a month or two if possible to put down the lime.
