Allium acuminatum (Taper-Tip Onion)
Those folks who follow me know my passion for nature and my joy of photographing all types of images. A project I’ve been working on for several years now is the native plants as there about to open for the first time. Here is an native onion we planted in Sally’s garden ten years ago. It’s a real joy for me to explore this small world in depth often getting lost for hours. Working in high magnification requires more attention to detail than one could imagine at times. This final focus stack image needed nineteen photos to achieve the depth of field to show the entire flower in focus.
Allium acuminatum produces bulbs that are spherical, less than 2 cm across and smelling like onions. Scape is up to 40 cm tall, wearing an umbel of as many as 40 flowers. The flowers are pink to purple with yellow anthers.
The onions were eaten by first peoples in southern British Columbia. They were harvested in either early spring or late fall and usually cooked in pits. Both the bulb and the flowering stalk are edible; however, in the culinary arts, the stalk possesses a more pleasant flavour.
