Here's what I have blooming right now in zone 8:
Cyclamen hederofolium -- one of many has not yet quite blooming for its season, as later-blooming species supplant the greater floweriness: Cyclamen coum Cyclamen cilicium
Camellia sasanqua "Rosea" thick with pink single-blossoms Camellia olifera x hiemalis "Showa-no-Sakae" full of pink double-blossoms Camellia olifera x hiemalis "Snow Flurry" with several white doubles
Crocus laevigatus var fontenayi, winter crocus
Viburnum "Dawn" full of pink flowers on its leafless branches
Kaffir lilies -- three cultivars take turns blooming so that one or another has flowers any season of the year; "Mrs Haggerdy" is in full bloom right now.
Abelia "Edward Goucher," not as flowery as during autumn but still pretty flowery
Cornus canadensis, Bunchberry. Though it doesn't really bloom anew in winter, its final autumn flowers that missed getting pollinated persist, turning from white to brighter & brighter pink as winter progresses.
Loropetalum chinense var rubrum "Sizzling Pink" Fringeflower, very nearly ever-blooming in my garden, plus the purple leaves are evergreen.
"Autumn Glow" Hebe. Bloomed like mad until November, still has a couple of limb-ends with bright purple blooms not quite finished.
Really feeble out-of-season blooms without their in-season stems are in close to the leaves of one bergenia, several chinese rampions, a cherry-bells campanula. Plus one patch blue siberian campanula hasn't as yet interupted its re-flowerings.
On the VERGE of bloom is witchhazel & a winterblooming honesuckle, but not quite yet.
There's a deluge outside right now or I'd take a tour about to see if I'm forgetting something cool. Most of the winter flowers are subdued, it certainly doesn't add up to a flowery show, except where the camellias are growing, those are showy as all heck. If one counted winter berries as being almost as good as flowers, there's a great many of those, from the neon-violet beautyberries to several kinds of red to orange cotoneasters & big white snowberries. The garden also gains some color from such things as Nishiki willow the newer twigs turning coral-red in winter, while the redtwig dogwood's younger limbs turn wine-red, & climbing hydrangea's thicker exfoliating limbs are bright orange. Birches & hazels also have catkins on them right now, but the catkins are not yet at maximum show which happens late-winter for the hazels & early spring for the birch, when the hard little early winter catkins turn into long soft golden chains.
I've a patch of winter irises that failed to bloom, wahhh.
