In Beekeeping, ‘Dearth’ means, a lack of or shortage of food and nutrients for the bee’s. Dearth is typically associated with late Summer, Fall and Winter. However even during springtime it is possible to have Dearth. Dearth can be created by negative weather patterns. Plants are tuned to specific weather patterns, and specific seasons. Disruption of any of these causes stress within the plant. As such, even though you may have flowers that normally provide pollen and nectar for our pollinators, climate conditions prior to and during play a role on whether the plant will actually produce what our pollinators need to feed on. “Nutrient Value” of pollen and nectar can also be affected by climatic conditions.
The Upper Rogue Pollinator Project is focused on utilizing plants that supply needed pollen and nectar during times of local Dearth. People creating ‘Pollinator Gardens’ should take Dearth into consideration when planting trees, shrubs and other flowering plants. This will provide an ongoing, needed, food source while other local sources are unavailable.
Undermanned, staffed, financed besides not a botanist or so on, (just a beekeeper) I’ve yet to get the names of many of these Dearth plants. Yes, some may be considered invasive. Will B following up on supplying more info besides adding more shrubs and trees. Most of what you will see here are drought resistant and flower at the end of summer when everything else is toast. However some fall plants are added in. click for full picture. If you have pictures of Dearth plants to offer (with names?) thank you. They will be posted.
Summer/late summer, don’t have all the names but below you have the Rose of Sharon, Russian Sage, Hydrangea (Hydrangea paniculata), Some type of Tulip shrub that is PHENOMENAL for all pollinators besides even flies and wasps.
this is whats called Rabbit Brush (chrysothamnus nauseosus) by Beekeepers. My personal experience with it is it has the same qualities as Almond pollen. The bees explode with energy from it. It produces both nectar and pollen. Blooms late July early August.Above is another variety, Ericameria nauseosa.
Unfortunatly we are still using the WordPress base for the website and are limited to the amount of pictures we can post. One of the reasons for converting the website over to its full potential. Other great Dearth plants include Lavender, Blue Bird Shrub ( Caryopteris varieties), Butterfly Bush (Buddleia davidii), Oleander (Nerium oleander),Dandilions, Again, please B interested in sending me other pictures of Dearth period plants with their names to be posted here. The pollinators will thank you.
