Campanula, there are so many that maybe it would be easier if you give a few names that look interesting to you and people can say if they've grown them from cuttings or seed.

forsythia of course ...

lilac... can be had from suckers ... of which i have knocked on many doors for such ...

same with currant ... alpine currant in my garden ...

maybe more later... ken

craving juneberries and sakatoons

all sorts of abelia (noticed many more interesting varieties other than the usual unnamed one which seems to appear everywhere

rubus - since blackberries are supreme victors in my woods, why fight against the bramble tendency.

evergreens - obvs I have the usual yew, holly and a few conifers but need more - lots more

viburnums - used to be quite scoffing at the viburnum trend - in fact, when confronted with a shrub I didn't know the name of, I would confidently assert it was a viburnum - never once got called on it. However, both these and hydrangeas are being seen with new eyes.

So yep - hydrangeas

corylus - not just avellana but pauciflorus (or summat - not terribly good at taxonomic spellings) and others.

escallonias (something I used to have, then got snobbish...but hey, now I have space

shrubby honeysuckles (not the climbers but tatarica etc. (and not that horrid little nitida)

some of the shrubs I can think of, off the top of my head, but obviously, am here for inspiration or I could just stick with weigela and lilac but...meh.

Have never been terribly keen on those yellow things - forsythia, jasmine, kerria...but suspect days of being a plant snob are behind me now.

Shrubby honeysuckles are easy. L fragrantissima is a poke a stick in the ground job. I've also done Hydrangea and Escallonia by this 'method'.

Given your conditions I was wondering about some of the classier Pussywillows. I don't know the name. Isn't there one with black stems? The coloured stemmed dogwoods are easy too, I believe.

I also dislike Kerria japonica in its double form but I like the singel and have grown it from cuttings. A cinch.

Do you like Mahonias? They're easy from cuttings too.

One I grew from berries is Symplocos paniculatum - the fruit are an unbelievable shade of blue. Which is why I picked some off the ground in an arboretum. Probably shouldn't have and still feel rather bad about it.

Hydrangeas are easy from cuttings or in the case of H. arborescens, suckers. Many viburnums start easily from seed and I think from cuttings as well.

Based on my woodlands, white pine/Pinus strobus, balsam fir/Abies balsamea and Canadian hemlock/Tsuga canadensis all grow readily from seed.

Any of the caning shrubs will strike quite easily from cuttings or from root divisions (shoots or suckers). Many have been mentioned already - forsythia, lilacs, shrub willows, twig dogwoods, hydrangeas. But also include deutzia, philadelphus, kolkwitzia, spiraea, chaenomeles, Symphoricarpos (snow or coral berry), clethra, corylopsis, weigela.

do you have.. or know about NEARING FRAMES???? .... ken

Oh, these look like erect coldframes - which I use loads off - usually just a couple of courses of blocks with a window balanced (precariously) on top.

Way back when I started gardening, flowering shrubs seemed a terrific wheeze - easy, large (this was very important) and often fragrant as well...and in a very short space of time, the garden, and later the allotment, were filled with shrubs and roses - nothing special, just the usual stuff...but I did develop something of a fad for deutzias and philadelphus so may have to reprise some of those old faves.

I already have white pines, lacebark pines and p.radiata growing from seed and will carry on doing tree seeds as they are so rewarding and I think I still have time to get going with hydrangeas (cuttings). I never had much luck with either leycesteria or cotinus - (those hollow stems) so suspect there must be a better way of propagating other than my usual hardwood (easy-peasy )methods...and I am just beginning to get a huge craze on for myrtles.

Salix - indeed, I have a whole area devoted to salix - the black kesselringii and purple daphnoides are beginning to achieve a bit of stature (I think I planted about 17 varieties as cuttings) - I do a bit of basketry so I really fancied growing my own osiers (Dicky meadows, viminalis, etc.) and have ensured they are on the south/eastern corner to get the early light through the stems. Going for chestnut and alder coppice too.

Amazingly, I had utterly forgotten about those white flowered honeysuckles - odd since there is a huge stand of them not 20metres from my house.

See, I knew GW (I can't bring myself to call it Houzz) would come through for me!

and thanks for reminding me about kolwitzia - these shrubs fell from grace a bit in the UK so will have to scrabble about in friend's gardens.

Yeah Flora - I have porcelain berry vine (ampelopsis) I (ahem) stole from berries in our local botanics...but unlike you, I don't feel bad about it (especially since they now charge an eye-watering entrance fee).

I also intend to grow berrying things like firethorn and cotoneaster - cuttings? or seeds?

Indeed - rowans have long been a favourite small tree - my eldest is named Rowan and uses the soubriquet 'Uncle Sorbus' on social media...and as he is a professional gardener, it turned out to be a prophetic choice of name.

Buy some plug/trays of grasses? Make lots of starts of Sedum telephium from just a few plants? Ask for Hydrangea trimmings?
