indian plum

Blooming now is Indian Plum (Oemleria cerasiformis). It is one of the first native species to flower in spring, and according to one authority (USDA/NRCS Plant Fact Sheet), its flowering coincides with the arrival of the Rufous hummingbird to our northern regions. It is also an early season nectar source for moths, butterflies and native bees. To the native bee claim, I can attest to — I was thrilled to see 3 bumblebee queens recently, but was not swift enough to photograph them in focus. Lots of great (read: non-usable) very blurry shots though!

Cool thing about Indian Plum is that there are male trees (left image) and female trees (right). Apparently this sexual divide can vary, and at times, there can be trees with both male and female flowers on it. (So, is this tree evolving towards or away from insect pollination?)

The male flowers have 15 stamens that produce lovely gold slightly-greenish pollen. The male plant has rather a weird odor to it – one writer suggested the descriptor: ” much like cat urine” (Radical Botany). The female plant, whose white flowers are slightly smaller than the male blossoms, produces little bitter fruits that are eaten by birds and other animals.  A fresh cucumber or watermelon-rind like fragrance emanates from the female plant.

This was a super plant to explore – lots of fun peering into tiny blossoms and sniffing for alleged tell-tale scents of girl and boy trees!
