Spiny Broom Enfleurage Experiment

The spiny broom has been early to rise this year, creating yet another challenge in realizing my dream to extract it. It is still cold, rainy and I can't for the life of me figure out when is the best time to harvest this thorn. I did one harvest, and discovered yet again that the scent is too faint, perhaps the flowers are also a bit too old and worn-out. The ones I picked which were fragrant lost their odour by the time I got to the studio to place them in the fats for enfleurage extraction. It is becoming rapidly more evident to me that knowledge of the exact harvest time is key to success in enfleurage. I did a small trial, but the scent did not stick around at all. Considering the painstaking process and how much pain is involved (if you're not careful and get stung by the thorns it literally hurts) - I think it would rather wait till later in the spring when the non-spiny (read: thornless) broom is in bloom. Wish me luck please!
