Deltona’s pollen seasons
The geography, climate and plants behind each season here, with a source for every fact.
Freezes leave only a short gap in the growing year at Orlando Sanford airport, 9 miles from Deltona, where about 352 days separate the last spring freeze from the first fall freeze in a typical year.1 Winters there average about 62 °F.1 At Daytona Beach, in the same metro area, the National Weather Service office in Melbourne puts the median start of the wet season at May 30 and of the dry season at October 15, based on records since 1950.2
Red maple, which grows wild in wet areas as far south as mainland Monroe County, flowers between January and March, when blooms are scarce.3 Live oak, whose range runs through Georgia and Florida to the Florida Keys, flowers every spring from March through May.4
In fall, saltbush flowers profusely along roadsides and ditches.5 Each saltbush plant is either male or female, and the shrub’s pollen is a known allergen.5 Bahiagrass, the most abundant grass in Florida, is high on UF/IFAS’s list of allergenic plants.6 Grasses in the state pollinate in spring, summer and fall.6
