Step outside after 6 p.m. in San Carlos right now and the air smells like perfume. Not from a candle shop. Not from someone’s dryer vent. From the jasmine. It is on every fence, every trellis, every arbor in every neighborhood from White Oaks to Devonshire to the streets above Arguello. If you have taken an evening walk this week, you know exactly what we are talking about.
Late May is when the Peninsula stops being “sort of spring” and becomes fully, aggressively, overwhelmingly in bloom. Here is what you are seeing (and smelling) right now, and what it all actually is.
✨ Star Jasmine (The One on Every Fence)
Trachelospermum jasminoides. Not true jasmine (that is a different genus), but nobody cares because it smells incredible. The small, white, pinwheel-shaped flowers clustered on dark green vines that cover fences, walls, and arbors throughout San Carlos.
Peak bloom: right now. Late May through mid-June. The fragrance is strongest in the evening when the air cools and the oils release. That is why your 7 p.m. walk smells like heaven and your noon walk does not.
Can we put it in an arrangement? Yes. We clip trailing jasmine vine and tuck it into bouquets and centerpieces when it is in season. It is delicate and does not last as long as most cut flowers (3–4 days), but the fragrance in a room is extraordinary. If you want jasmine in your arrangement this week, ask — we likely have it.
🌸 Bougainvillea (The Magenta Walls)
The hot pink, magenta, orange, and purple cascading over walls and fences on south-facing houses. Bougainvillea loves the Peninsula’s dry warmth and reflected heat from stucco walls. What most people do not realize: the colorful parts are not flowers. They are bracts (modified leaves). The actual flowers are the tiny white tubes inside.
You are seeing it explode right now on El Camino, on the houses along Cedar Street, and anywhere a south- or west-facing wall collects afternoon sun. It will keep going all summer.
Can we put it in an arrangement? Not really — it wilts almost instantly when cut. But we carry similarly vibrant stems: hot pink roses, magenta stock, and fuchsia peonies that capture the same energy.
🔵 The Blue Bush Nobody Can Name
You have seen it. You have probably photographed it. A massive shrub covered in dense spikes of electric blue or purple flowers, usually 6–10 feet tall, buzzing with bees. That is one of two things:
- Ceanothus (California lilac): A native shrub with tiny, dense clusters of blue-purple flowers. Evergreen. Drought-tolerant. All over the Peninsula hills. Peak bloom is right now, slightly past in some spots.
- Pride of Madeira (Echium candicans): The towering purple-blue conical spikes, 3–4 feet tall, on huge silvery-green plants. Not native (from the Canary Islands) but utterly at home on the California coast. You see these along highway medians, parks, and neglected lots where they have taken over beautifully.
Neither works as a cut flower. But for that intense blue in an arrangement, we use delphiniums, hydrangeas, or thistle — the closest equivalents to what you are seeing on the hillside.
🌹 Front-Yard Roses (Peninsula Rose Culture Is Real)
San Carlos has serious rose gardens. Walk Elm Street, Cedar Street, or the blocks around Arguello Park and you will pass dozens of front yards with hybrid teas, David Austins, and climbing roses in full first flush right now. Late May is the first major bloom cycle for roses on the Peninsula — they opened this week and will keep going through June.
What we carry in the shop: garden roses from California growers that look and smell like what you see in those yards. Juliet, Keira, Quicksand, Patience, and seasonal spray roses in every color. If you love the roses you see walking your neighborhood, we can put that same energy on your table.
🌿 Lavender Lining Driveways
The silvery-green mounds along driveways, walkways, and front borders that just burst into purple spikes? That is lavender — mostly English lavender (Lavandula angustifolia) or the showier Spanish lavender (Lavandula stoechas) with the “rabbit ear” petals on top. Peak bloom on the Peninsula is right now through June.
Lavender works beautifully in arrangements as a texture stem and fragrance element. It also dries perfectly — an arrangement with lavender today will still smell good in two weeks as dried stems in the vase.
🌼 The Other Things You Are Seeing
- Agapanthus (Lily of the Nile): The tall stems with globes of blue or white flowers in median strips and parking lots. Just starting to send up stalks now — full bloom in June and July.
- Society garlic: Low purple clusters along walkways. Smells like garlic if you crush the leaves. Blooming now.
- Pittosporum: The dark-leafed hedges with tiny cream flowers that smell like orange blossoms? That is pittosporum, and it is at peak fragrance this week. We use pittosporum foliage in arrangements constantly.
- Mexican sage (Salvia leucantha): Fuzzy purple spikes on arching stems. Starting its first bloom now, will go all summer.
- Geraniums: The red, pink, and salmon clusters in every window box and pot on every porch. Not glamorous, but reliable and everywhere.
🚶 The Evening Walk as a Flower Tour
If you want the best “what’s blooming” walk in San Carlos this week:
- Start on Laurel Street downtown — the planters and restaurant patios have seasonal plantings and the street trees are leafed out.
- Walk up Cedar or Elm toward the hills — this is where the rose gardens and jasmine fences are densest.
- Cut through Arguello Park — the beds around the edges have California natives and seasonal plantings.
- Head toward Laureola Park or Big Canyon — ceanothus and wild coastal plants on the hillside trails.
- Loop back via the Crestview neighborhood — bougainvillea on the south-facing walls, lavender along the driveways, and jasmine perfuming the air as the sun drops.
Go after 6 p.m. That is when the jasmine fragrance peaks and the light turns golden on everything in bloom.
💐 Bringing the Walk Home
Here is what we can do: build you an arrangement that captures what you are seeing and smelling on your evening walk. Jasmine vine. Garden roses. Lavender. Greenery that looks like it came from a Peninsula garden. California-grown, seasonal, and smelling the way your neighborhood smells this week.
That is what a local florist does. We are not shipping stems from another hemisphere and hoping they remind you of something. We are working with the same season you are walking through.
