Hi Brian,
It's called Hortonova Flower Support Netting. It can be purchased through G & M Agricultural Supply Company.
Telephone: 800/901-0096. They are a vendor for several large companies such as: Remay, De Witt, Modine, Texel (that's the support netting), Agra Tech, and many others. If you are also looking for row cover, weed barrier, plastic mulches, bird netting, deer fencing, and other field and greenhouse related supplies, it can be found in their catalog. Their office is in Arizona. I think the Hortonova support netting came from a Tenex warehouse in Chicago. We have only purchased the support netting through them because our local growers co-op did not carry this item. Anyway, we've called by noon; and, it arrived the following day via UPS Ground. Fast, fast service.

And, to remain fair and balanced, Johnny's Seeds also carries Hortonova support netting. I really like the folks at Johnny's; however, their cost is higher.

Also check out pricing from Specialty Agricultural Products in CT (800) 483-8889, thanks to a referral, I found them to be much more competitive than G & M Ag in Arizona, Gloeckner's or Johnny's, not only on product cost but shipping too.
BTW, it's a wonderful product, would be lost without it.
