I've done the reading, and THINK that I probably have the biennial stem type, but I am simply not sure. Is there any way to tell from the photos I've attached? The plants are about 1 metre tall and several years old. They flowered beautifully last year, more lime green I'd say than acid yellow.
I pruned back what I thought were last year's flowered stems to the base in the Autumn.
So far there is a little re-growth, though I shd be expecting this to surge this growing season, setting themselves up ready to flower in 2022? Is that right?
As for the current large stems: one photo shows what looks to be a yellowish flower bud surrounded by purplish- tinged leaves in its tip. All current tips have these. Am I right? And therefore that these are all set to flower this year?
Also - the long stems look a little leggy and bare, not sure what if anything can be done about this? Or what I should have done / shd be doing in the future to prevent this?
I realise this is quite a lot to ask - but very much hoping you can help!
