I get a 'not responding' from your link. my laptop is Windoze (sp intentional) 10 and I use Firefox. I will try it on the desktop where I have Windows 7 and have Chrome, Firefox and Explorer. Not sure about the 'IE' thing. Will ask my daughter the techy whiz.
Assuming I could see what I am guying I would be in for 20 plants. Seems like we are way short of 1000. But then you said they might consider 500. I could go 30 but would hope that the botanical garden would let me 'store' them in their research beds assuming I could get some that they would like to add to their collection in addition to the ones I want to keep. If I turned every bit of my remaining lawn into garden, I would not have enough room. But the ABG (botanical) could make a tidy profit selling them at their spring sale the end of May. So I would call it a charitable donation. Ummmm. Thinking that, bump me up to 40 assuming I can see them. I will try my desktop next.
