Have you ever thought of utting all of your wonderful ideas / tips into a book ?
Or might you already have one ?

I have never seen them flower but it is flowering now – just one inside – how do I collect seeds from it ? Let it die and then shake it into a baggie?

You’ve probably already dealt with them since I’m replying a couple of months after your question, but anyway… After the flower has done its thing, leave it alone until it dries out. You’ll know when it’s time to collect the seeds, because it’ll look like they’re pushing out of the papery leftovers from the flowers (they’re not, really – it’s just that the remains of the flowers are drying out and shrinking). The way I harvested mine was to put a ziploc bag over the flower and gathered it closed at the base of the flower, cut the stalk, then shook the flower head and ruffled it with my fingers through the bag.

Won’t go *to* waste (typos are a norm for me now- my hands don’t text well after moving a shovel all day! LOL
