Pansy Companion Plants 
Yes!...there are other plants that will thrive in the outdoor landscape during the winter months...and many of these are perfect for combining in beds and/or pots with pansies.
Ornamental / Flowering Vegetables - Perhaps the most popular pansy companions are the many selections of flowering cabbage and flowering kale, which are two among many colorful cool-season vegetables plants. These "flowering" vegetable plants can be used ornamentally in the garden and make perfect accents or centerpieces in combination beds or container plantings with pansies.
Evergreen Ornamentals - Evergreen conifers, such as the conical-shape Golden Arborvitae, Hetzi Column Juniper, the silver foliage Carolina Sapphire Cypress, Leyland Cypress and many others, make excellent centerpieces or backdrops for pansy plantings. Too, these conifers make perfect little Christmas trees that can be lighted during the season. In late Spring, when pansies are done, these evergreens can be removed from the bed or container and planted elsewhere in the landscape where they can grow to their mature size.
Bulbs - Tulips, Daffodils, Hyacinths and other spring-flowering bulbs can be planted at proper depths beneath pansies in garden beds or container plantings. In the Spring, foliage and flowers from these bulb plants will rise above or be nestled among your pansy flowers. Creative gardeners can really come up with some neat combinations of textures and color.
Fragrant Plants - To add fragrance to a pansy combination planting, plant Rosemary or Tea Olive - both of which are evergreen and flower during the cool season.
Other Cool Season Flowering Plants - Other cool season flowering annual and perennial plants, such as Dianthus, Diascia and Snapdragons provide a different texture and flower-look in pansy combination plantings.
Other annuals and perennials , such as Dusty Miller, Heuchera and perennial evergreen ferns, such as Autumn Fern, provide interesting foliage color and texture in pansy combination plantings.
