Yew

Another interesting discovery the other day – yew pollen! The conifer I found is a male (haven’t located a female plant yet). The tiny flowers that erupt from buds look like they have their own little pots or vases. They produce copious powdery, light pollen, as you can see from the image on the right. The tiny 3″ bit of twig which I broke off and took home produced all of that lovely creamy pollen.

According to Kirk (Plants for Bees), yew produces no nectar, although pollen is an early source of pollen for honeybees.

A note of interest perhaps, the poison “taxine” is found in all parts of the tree, and even though the poisonous fleshy red seeds that the female trees produce are eaten by birds, they aren’t adversely affected by the seeds. A chemotherapy drug, Taxol, used for the treatment of breast cancer,  was initially manufactured from the bark of Pacific Yew (Taxus brevifolia).

muscari

A late start to the new year’s postings, but the pollen has been on my radar since December. I’ve collected several samples of winter flowering plants, and am beginning this documentation with the latest one, muscari (sp), which I purchased today from a local nursery just because I couldn’t wait for the muscari in my garden to bloom.

According to Kirk (Plants for Bees), these tiny cobalt-blue bells with the white scalloped collars offer both pollen and nectar to bees. Honeybees benefit from the early pollen source, but bumble bees and solitary bees also visit. Muscari is a fragrant delight.

I’ve attempted to dissect one of the miniature blooms.  6 dark anthers that appear to be attached to the walls of the corolla,  dehisce a creamy yellow pollen. Sonicating the blossoms helped with the process of pollen harvesting.
