I've found a use for all those black echium leaves that die and drop.
A "mulch" of cut up bramble stems and cut up multi-needle array echium
leaves keeps cats, slugs and snails away from other plants.

Young summer-sown echium plantlets don't seem to like being under glass
in the heat of summer, liking some shadding and outdoors.

Some germination observations.
Seed 6 months on from flowering germinates fine, older may be less and
less viable.
But with all the recent rain presumably. A house in a neighbouring road
used to have flowering echiums up till 3 years ago.
But in the last month or so in the pavement curtilage gaps of 2 houses 3 houses either side of it, have little echium plants growing. I've
advised to train them thru gasps in their fences

The main echium this year topped out at 4.2 metres or 14 foot allowing
for the bend in the stem. Seeds should be dropping in the next week or
so. Last year I collected thousands of seeds, giving away plantlets from
them this year.
I thought I was observant. Checking the ground last year and this year I
was surprised not to see any self sown plants.
2 doors down between his front wall and the public pavement in the gap
dirt, half a dozen borage plants I thought. But bending down for a
closer look the leaves have the tiny black dots of echium.
So I checked "my" pavement dirt strip and I'd been daily walking over
another half a dozen plantlets at the front garden path step down to the public pavement. I've no idea if they were there last year and survived
the winter or just this year with March drought but obviously survived
the heatwave last week. I need to transplant mine and see the neighbour
about moving his as 14 foot spikey voluminous plants growing next to the public pavement is far too much . I suspect deep tap roots to have
survived last week and perhaps March drought, so will probably damage
them ,pulling them up. Will try rooting compound and wet compost.
Talking to an IoW echium afficianado his first plants came from pulling
up and transplanting a few , he found in a pavement at Ventnor Botanic
Garden (again would not have been allowed to mature in that self-chosen
spot ).
