The Best Flowers for LA's Climate

The best flowers for Los Angeles are heat-tolerant, California-grown seasonal stems. At Adore Flowers, ranunculus and anemone carry the cool months, dahlias and lisianthus carry the heat, and chrysanthemum and orchid hold up all year.

Heat is the thing that shortens a vase life here, more than water and more than light. Choosing stems built for this climate is the simplest way to buy an extra three days. Here is what thrives, what struggles, and what to send in an August week.

What does LA's climate ask of a flower?

It asks for tolerance of heat and bright light, and for a short trip from the field to the vase. Los Angeles sits in a Mediterranean climate, one of only five regions on earth with one, marked by mild, rainy winters and hot, dry summers. Flowers bred for cool, damp summers do not enjoy that, and it shows on day three.

The second half of the answer is distance. A stem that has spent three days in transit arrives with less water in it and less time left, and heat finishes the job.

Which flowers do best in Los Angeles?

Cool months. Ranunculus, anemone, tulip, paperwhite, camellia and hellebore. Our winters are mild enough that these run long here.
Warm months. Dahlia, garden rose, zinnia, cosmos, lisianthus and hydrangea, all of which come into their own in the heat.
Autumn. Chrysanthemum, marigold, celosia, amaranth, and the seed heads and branches that give an arrangement structure.
Year round. Orchid as a plant, and chrysanthemum and alstroemeria as the durable backbone of a mixed piece.

Dahlias deserve their own note. UC's Statewide Integrated Pest Management Program records that they bloom from early summer into winter in California, which is why they carry half our year.

Which stems hold up best in the heat?

Chrysanthemum, alstroemeria, lisianthus, zinnia and orchid. These keep their shape in a warm room long after a soft-petaled stem has given up.

They are what we reach for when an arrangement has to survive a Los Angeles afternoon and then a weekend. Lisianthus in particular is the quiet workhorse of a summer design.

The trade-off runs the other way too. A fully open garden rose and a ranunculus at their best are worth the shorter peak, so most arrangements mix both and shift gently instead of fading at once.

Which flowers struggle in Los Angeles?

The ones bred for cool, damp summers. Anything that wants a long chill, or that arrives already tired from a long flight, has a hard time in a warm room here.

Peony is the honest example. It is worth every day of its short window in May, but I will not sell it into a hot week in August and pretend it will hold.

Do California-grown flowers actually do better here?

Usually, because the path from field to vase is short. Stems cut a day or two away reach the recipient near the start of their vase life rather than the end.

There is also simply a lot to choose from. California supplies over 75 percent of all domestically grown cut flowers in the United States, so buying local here is not a compromise on range.

We buy in the Downtown Flower District and from growers up the coast. The flowers are suited to the climate they are delivered into, which is the whole point.

Do the Valley and the coast need different flowers?

They do, more than people expect. The same arrangement has a much harder afternoon on Ventura Boulevard in Sherman Oaks than it does two blocks off the beach in Santa Monica. For an inland address in high summer I build with more chrysanthemum, lisianthus and foliage, and I keep the softest stems for the coast and for the cooler months.

What should you order for a hot week?

Ask for a seasonal designer's choice piece and say where it is going. The everyday collection starts at $150 and leaves the studio the same day on orders placed before 11 AM, Monday through Saturday.

The signature collection shows the same seasonal buying at a larger scale. Our guide to keeping flowers fresh in the heat covers the care once they land.

Questions, answered

What flowers do best in Los Angeles's climate?

Heat-tolerant, sun-loving, California-grown seasonal stems. Ranunculus and anemone through the cool months, dahlias, zinnias, garden roses and lisianthus through summer, and chrysanthemum and orchid all year.

What flowers survive the heat best?

Chrysanthemum, alstroemeria, zinnia, lisianthus and most orchids. They hold their shape in a warm room far longer than a fully open garden rose or a ranunculus does.

Are California-grown flowers better for LA?

Usually. A shorter path from field to vase means the stems reach you near the start of their vase life instead of the end, so they open on the table rather than in transit.

Do dahlias last in Los Angeles heat?

They grow well here and bloom from early summer into winter, but cut dahlias drink hard and dislike a hot room. Keep them out of afternoon sun and top up the water daily.

Which florist near me designs for the LA climate?

We buy seasonal stems in the Downtown Flower District and design around what thrives here. Arrangements start at $150, same day on orders before 11 AM, Monday through Saturday.
