What part of plant to use for distilling?
OK, some are easy, lavender *flowers*, or rosemary *leaves*, but what about cedar? Do I use wood chips or the needles? HOw about night blooming flowers? They are only good for one night, so can I pick them that very night and process them right away, or won't they work at all? And here's an off the wall question, if I distill fresh mowed hay, will the oil and hydrosol smell like freshed mowed hay?
