Thanks, that would be awesome!

Helianthus 'Lemon Queen' is a lovely huge plant if you have room. It is also a bee magnet. I am a fan of that pale lemon yellow too.

Did a long post then Houzz vanished it. Anyway, try again...

Bidens - either tall (heteropyhlla) or short (ferulifolia), aquilegia chrysantha, various iris, roses - from the dainty Dunwich Rose to massive climbers such as 'Mermaid;, with my username, rosaprimula also filling your brief.

Second Karin's "Hyperion' and also add citrina, Marion Vaughn, Lemon Chimes. Had others but have forgotten (10 second memory bank - worse than a goldfish!) Sure to add more, laters.

I would call Achillea 'Moonshine' lemon yellow.

ranunculus 'Citrine', achillea taygetea 'Moonshine', primula vulgaris, a particularly good and reliable returner tulip - 'Ivory Floradale'..but also see tulipa batalini, anthemis 'Susannah Mitchell' and 'E.C.Buxton', chrysanthemum coronarium and c.segetum,

I blanked on Daylily 'Big Time Happy'. Daylily 'Double River Wye' is a touch brighter a yellow but still in the same vein.

ETA: Digitalis grandiflora. Some Siberian Iris such as 'Butter and Sugar'.

Cosmos 'Xanthos', uruspermum dalechampii, echinacea 'Sunrise', digitalis 'Foxy Primrose', also digitalis lutea, osteospermum ' Buttermilk', sisyrinchium striatum, sisyrichium palmatum 'Canary', Geums 'Lisanne' 'Bell Bank', 'Lemon Drops, 'Tequila Sunrise', corydalis ochraleuca, scabious ochraleuca.

Daylily 'Tetrina's Daughter': very fragrant, and I like the shape of the flower better than 'Hyperion'. Daylily 'Penny's Worth': tiny rebloomer, under 12" I think.

No response from garden fanatic - are we shouting into the void?
