Prolific nectar plant whose flowers rapidly replenish their nectar during the day; borage seed fields yield a pale honey.
Borage is a Mediterranean annual grown in gardens, along vegetable plots and on a field scale for seed oil. Its nodding blue flowers quickly replenish their nectar after it has been taken, so the same flower is visited many times a day. Nectar secretion lasts from morning to afternoon and continues in mild drought. Its pollen contribution is moderate.
Sown in April-May, it flowers from June to September; with successive sowings and self-sown seed, flowers can be seen until October.
In England and New Zealand a monofloral honey is obtained from borage seed fields; it is very light in colour and mildly sweet. The pollen loads are greyish white.
It is one of the best plants for sowing on small plots around the apiary; sowings a few weeks apart extend flowering. The plant contains low levels of pyrrolizidine alkaloids; it is advisable to have honey from large borage fields analysed.
