Have a garden with Day lillies and pachysandra. Which one will end up taking over the garden?
Daylilies do not self-sow and clumps slowly increase in size. In fact, the clump will decline and look dead in the center if you don't divide it every 5 years or so. Pachysandra surely spreads but is not aggressive in my experience. One likes sun, the other shade. Daylilies like some fertilizer if they are repeat bloomers; don't fertilize pachy.
