After being at the Bend Seed Extractory for nearly a year, I can open most seed collections and know immediately which cleaning method will bring the best results.\u00a0 This was not true of my “challenge of the week”, Grindelia squarrosa <\/em>(GRSQ).\u00a0 Members of the aster family are\u00a0usually difficult because the seeds\u00a0are often fragile and\u00a0come accompanied\u00a0by a\u00a0lot of vegetative material.\u00a0 This collection of GRSQ, or curlycup gumweed, \u00a0held true to those characters of the aster family but had\u00a0some additional challenges – the exterior of the flower heads were sticky and prickly.<\/p>\n

Without the sticky material, I would have no hesitation to put this collection in a brush machine, but my worry was that the brushes and the seed would become coated with the goo, making the finishing process much more difficult.\u00a0 So, what to do?\u00a0 Whenever I find myself asking this question, I turn to the incredibly knowledgeable staff at the extractory for advice.\u00a0 The recommendation was to use\u00a0baby powder, and lots of it.\u00a0 We often add powder or corn starch to seed lots\u00a0to control static, but I always forget that it can be useful for coating sticky and coarse-hairy\u00a0trash so that seed won’t attach to it.\u00a0 I jumped on this advice and decided to change the brushes in my machine to paddles, just in case the goo\u00a0was too much for\u00a0the powder.<\/p>\n

One pass through the brush machine after a good dousing with powder and…success!\u00a0 The flower heads were broken up\u00a0and the seeds were flowing freely.<\/p>\n

Considering that this species was not only tricky to clean, but smelled like dirty gym socks and released itchy hairs into the air, I was happy to\u00a0send it along to the next phase of cleaning.\u00a0 I hope it doesn’t pass my way again, but at least it taught me a few new tricks.\u00a0 On to the next challenge…<\/p>\n
