2312More Sources for flower Nectar
- Sep 4, 2012If you are living in southern California or Hawaii you may have access shrubs and small trees from Australia and South Africa that belong in the Proteaceae (macadamia nut family). Grevilleas and Banksias, in particular secrete oodles of nectar but it is usually a hexose rich (mostly fructose and glucose) nectar consumed by passerine birds in the natural habitats.Peter---------- Forwarded message ----------

Jack is right, I would not want to hand collect enough nectar for feeding for most plants. If you resort to centrifugation, keep the RPMs down, as I found with alfalfa buds that you can also extract phloem sap! If I were to manually collect nectar from one readily available plant, it would be a summer squash, esp zucchini. Each flower has a veritable lake of nectar in it (up to 120 ul) that is readily removed with a syringe (ideally with a blunt-tipped one). Mature buds can be bagged the night before so you aren’t competing with bees early the next morning. If you live in a place where bat-pollinated flowers can be grown or grow, then there are some other options like this (e.g. agave and some bat-pollinated vines). But for sheer convenience, squash.
