I also managed to gather quite a bit of elderflowers. These made great distillate this year too. We have had tons of rain and all of the plants are big and strong so I would imagine it has a a big effect on the flowers too.
I have been really excited about my rose bushes too but only 1 bush has made any flowers and it only has made 2 so far. I think next year, which will be their third year, will be a production year. They have been shooting up from all the rain though so I suppose I could still get some flowers to work with. Just not holding my breathe on it.
The catnip is HUGE! I need to cut it down but I hate to, because I have tons of honeybees on the flowers.
