If THEY are against us planting food crops in the Front Yard - Then we should have every right to yank up poisonous ornamentals out of their Front Yards. Not that I would, but why does the nursery/florist trades tend to market poisonous plants??
There many edible plants (food crops AND "ornamentals") that have even better attributes aesthetically...What a wonderful world if even just the Clematis(es(?)) & Daffodils were replaced by Passiflora sp, Daylillies, and Tulips.
