Winter Flowers for Southern California: What Blooms in the Cool Season

Written by Kelsey W.

One of the perks of living in Southern California is that gardens stay colorful even in winter. Our mild, Mediterranean-style winters are ideal for a whole range of flowers that bloom while much of the country is under snow. Whether you have a yard, a patio, or just a sunny balcony, here are the best winter flowers for a Southern California garden and when to plant them.

Camellia: the Rose of Winter

Known to some as the Rose of Winter, the camellia is a large, broad-leaved evergreen shrub that blooms from winter into spring, exactly when little else is flowering (Clemson Cooperative Extension). Camellia japonica flowers from roughly September to April, while the earlier Camellia sasanqua starts in late fall and carries into winter (NC State Extension). Camellias bloom best when sheltered from hot afternoon sun, so an east- or north-facing spot, or a bit of shade under a tree, is ideal. Give them a slightly acidic, well-drained soil rich in organic matter, and keep the soil moist but never waterlogged. Despite the nickname, a camellia is not a true rose; the name just describes its rose-like flowers.

Hellebore: the Christmas and Lenten Rose

The hellebore, often called the Christmas rose or Lenten rose, is another winter star that blooms in winter and early spring when little else does (Clemson Cooperative Extension). Like the camellia, it is not actually a rose: hellebores are perennials in the buttercup family, alongside clematis and anemone. They do best in shade or part shade, classically planted under deciduous trees where they catch winter sun and summer shade, in soil rich in organic matter that drains well, as they will not tolerate soggy ground. Southern California’s Mediterranean climate suits them nicely.

Cool-Season Annuals: Pansies, Violas, and More

For fast, easy winter color, nothing beats cool-season annuals. These are planted in fall and bloom through the cool months (Clemson Cooperative Extension). The stars are pansies and violas, cool-season annuals that brighten winter days and, planted in fall, can bloom for four to six months right into spring (NC State Extension). In our mild climate they often behave almost like perennials, carrying on nearly year-round, and they are perfect for beds, borders, hanging baskets, and patio containers with very little fuss.

Round out the bed with more cool-season favorites:

• Cyclamen: bloom from early winter into spring and love part to full shade, making them a classic winter container flower (NC State Extension).
• Calendula (pot marigold): cheerful orange and yellow daisies for full sun.
• Iceland poppy: papery, jewel-toned blooms on slender stems, best in full sun.
• Snapdragon: tall, colorful spikes that thrive in the cool season.
• Stock: fragrant, old-fashioned spikes in soft colors.
• Sweet alyssum: a low carpet of tiny, honey-scented flowers that spills nicely over edges and containers.

Reticulated Iris and Other Early Bulbs

If you love bulbs, the dwarf or reticulated iris is one of the earliest to bloom, flowering in late winter to very early spring, well ahead of the tall bearded irises (NC State Extension). It is a wonderful way to get a jolt of color before spring truly arrives. Cut back the flower stalks once the blooms fade but let the leaves die down on their own, and leave the bulbs in the ground: in frost-free parts of Southern California they will naturalize and spread, filling a bed over a few seasons.

What Flowers Bloom Year-Round in Southern California?

No single flower blooms every day of the year, but our mild climate makes near-continuous color easy if you plant a succession. Cool-season flowers like pansies, violas, calendula, and snapdragons carry you from fall through spring, and warm-season flowers take over for summer. Some plants stretch across most of the calendar on their own: in a Southern California perennial garden it is normal to have something blooming from early spring into early winter, and a few tough perennials flower in nearly every month (UC ANR). Pansies and violas, in particular, can bloom nearly year-round in mild coastal areas.

Frequently Asked Questions

What flowers bloom in winter in Southern California?

Camellias, hellebores, cyclamen, pansies, violas, calendula, Iceland poppies, snapdragons, stock, sweet alyssum, and early bulbs like reticulated iris all bloom through a Southern California winter. Plant the cool-season annuals in fall for color from winter into spring.

What flowers bloom all year round in California?

No single flower blooms every day, but because our climate is so mild you can have flowers year-round by planting a succession: cool-season bloomers (pansies, violas, calendula) for fall through spring and warm-season flowers for summer. Pansies and violas in particular can bloom nearly year-round in mild coastal areas.

What can I plant now for winter flowers?

In fall, plant cool-season annuals such as pansies, violas, cyclamen, calendula, Iceland poppies, snapdragons, stock, and sweet alyssum, along with camellias and hellebores, for color right through the winter.

Do pansies bloom in winter?

Yes. Pansies and violas are cool-season flowers that bloom through fall, winter, and spring in Southern California, and in mild areas they can keep going nearly all year. Plant them in fall for the best winter show.

Is a camellia a rose? Is a hellebore a rose?

No. Despite nicknames like “Rose of Winter” (camellia) and “Christmas rose” or “Lenten rose” (hellebore), neither is a true rose. The names simply describe their rose-like winter flowers; hellebores are actually in the buttercup family.

What is the easiest winter flower to grow in Southern California?

Pansies and violas are the easiest and most forgiving winter flowers here, thriving in beds, borders, and containers with little care. Calendula, sweet alyssum, and cyclamen are also very easy for winter color.
