Just had to add my thank you to the many, Larry, for such a timely and thorough article.
In the case of coleus, a single picture is at least worth a thousand words...so you've saved yourself an awful lot of words! I suspect you have created a good run on Coleus this year all by ourself with this informative article. You've certainly opened my eyes to some more possibilities. Thanks again for teaching an avid gardener something new...now I'm off to make the rounds of this season's first to open garden centres in the center of British Columbia, Canada. I'll have to wait a while for those warm loving coleus though.
