Boxwood is a great filler for indoor and outdoor seasonal arrangements. Outdoors it is best sheltered (pots on a porch); if it is fully exposed to the elements it can darken in the extreme cold of January and February. Indoors ensure it is in water or oasis to retain freshness. Dried, it is effective too, but leaves do go crinkly.
Boxwood can be used on a mantle, in vases or created as wreath. Snipets can be effectively used as present toppers.
