3 local flower shops in San Mateo County
South San Francisco has three florists, the 9th largest selection in San Mateo County, where San Mateo accounts for 11 on its own. That is a small enough choice that same-day work is worth phoning about rather than assuming, particularly on the run-up to a holiday when a small shop books out quickly. Two list a website; the other takes orders by phone.
If nothing here suits, the nearest larger choice is Colma, about 2 miles away, with 7 florists. Bear in mind that a shop delivering out of its own town will usually charge more for it and may need more notice.
Summer brings the widest choice of the year, including dahlias, which travel badly and are therefore almost always local wherever you find them. Coastal fog keeps things cooler than inland, so a florist near the water is working in kinder conditions than one in the valleys.
