I’ve long been a sucker for plants with showy foliage, often falling for their pretty leaves without careful consideration of their sometimes less-than-attractive habits. I don’t much mind plants that produce lots of seedlings; if they’re truly gorgeous, having to snip off the spent flowers or weed out excess offspring seems a fair trade.
Plants that sneak around by creeping roots or stems are another matter. They look all cute and innocent for the first year or two; then suddenly, they’re popping up everywhere and generally making a nuisance of themselves. If I suspect or know for sure that a plant is likely to be a creeper, I’ve learned to trial it in a pot first.
