i see i've been missing local flower shows too! i read that he does topiary, but coleus is a rather difficult subject for overwintering, i'd think. though i did overwinter it once on a sunny window. that 3 seasons booth is fab! i also just found out about nj state flower show in feb - will be in edison this year. i'll try to come, weather permitting.
last winter was rather cold here, it's a shame if they lost a lot of stock in greenhouses. and here i was rejoicing that finally i'll be able to get a special coleus or too...
