I think it may be hard to find that many at one place, without ordering them. I don't know if either of these places would be a source or not, but I would check Thress Nursery (in Powell) and maybe Kinsey Gardens (on Rutledge Pike). Kinsey is wholesale, but if they hear you need that many, I bet they would talk to you.

I would be surprised, if you talk to both of these places, if they couldn't at least get these plants for you.

The Liriope in front of Sam's at EastTowne/Knoxville Center has huge amounts of seed on their Liriope.
Would you consider starting your own from seed?

i haven't talked to thress or kinsey. i've been dealing with another dealer, who is pricey. they did give me a wholesale discount on some skip laurels i recently bought....65 of them. but i know i can do better.

i didn't know one can plant liriope from seed. i really want a thick groundcover on my hill....and this is a great plant for me, i believe. is it hard to start from seed?

i'm not looking forward to making 1000+ holes....i did that on another hill where i planted about 3500 vinca minor. the size of this hillside is about 200 feet by 20 feet. the other hillside was about a factor of 3 longer.
