A
honey bee collecting nectar from an apple flower.
The nectar source in a given area depends on the type of vegetation present and the length of their bloom period. What type of vegetation will grow in an area depends on soil texture, soil pH, soil drainage, daily maximum and minimum temperatures, precipitation, extreme minimum winter temperature, and growing degree days. The plants listed below are plants that would grow in USDA Hardiness zone 5. A good predictor for when a plant will bloom and produce nectar is a calculation of the growing degree days. Hopkins' Bioclimatic Law states that in North America east of the Rockies, a 130 m (400-foot) increase in elevation, a 4° change in latitude north (444.48 km), or a 10° change in longitude east (two thirdth of a time zone) will cause any given biological event to occur four days later in the spring or four days earlier in the fall. In botany, the term phenology refers to the timing of flower emergence, sequence of bloom, fruiting, and leaf drop in autumn.
The classification in major or minor nectar source is very dependent on the agricultural use of the land. Agricultural crops like canola and alfalfa may be a major or minor source depending on local plantings. Honeydew sources are not included in this listing.

feral In California, spring blooming plant with repeat bloom. Fall bloom provides nectar for bees for overwintering. The most unusual feature of Echium vulgare is the protection of the nectar inside the flower from vaporization (when it’s hot) or flushing away (when it rains). It is why almost for 2 months this plant is a stable source of nectar for bees. Additionally this plant produces nectar throughout the day unlike most plants which produce nectar for a short period of time. If the bees have a good access to Echium they can collect between 12-20 lbs of nectar a day. The concentration of sugars in the nectar vary 22.6-48.3% depending on the quality of the soil, and not on the amount of rain. The honey is light amber in color and ver y fragrant with a pleasant taste, and does not crystallize for 9–15 months.[2] |
