Texas Smartscape says a great thing about using a perennial is that they get hard each winter season (or “harden off”) and then re-bloom year after year, saving you time and money each spring. A perennial flower will usually drop its color foliage bloom about the first cold snap in fall and will harden off when water freezes.
Cut perennial back for winter, trim dead stalks in spring
You can cut a perennial back to just above ground level to keep your flower beds looking clean all winter, and then in the spring the new flower bloom growth will start. This also helps protect the perennial plant from hard freezes.
Minimize your maintenance with a perennial
No running out in the cold to put a cover over your flower plants each night as it drops below freezing. If you design your flower beds using the perennial plants listed here and a little water and fertilizer, you can have a great looking garden year round with very little work and great color.
