Hi all,
A neighbour of mine has a lovely yellow flowering shrub that looks like Rudbeckia Goldsturm, Black Eyed Susan. I want to grow this & was wondering what tips you can give me. Can I take a cutting now? Or should I grow it from seed next spring. Any tips will be great fully received.

You could ask your neighbour if they would give you a root cutting in the spring.  Seeds however will give you many more plants. I Fancy growing some from seed myself as I love rudbekias but never grown the perenials.

I've got about 30 Rudbeckia growing in 3" pots that I sowed in spring, dead easy and great germination. They got a bit potbound and dried-out in 2" pots and a few even flowered this summer from the stress I think!

looking forward to next year!

Hi All,
You may have already seen my post regarding a perennial plant my neighbour has got & I posted asking was it  Black Eyed Susan aka Rudbeckia Goldsturm.
Well here some photos of the plant to help in identification.

So what do you all think it is ? Is it as I thought Rudbeckia Goldsturm ? It is about 1.2 metres high, the RHS plant finder has Rudbeckia Goldsturm at 60cm

I've merged your threads together to keep it tidy

It certainly looks like Goldsturm

Really jealouse.I've never manager to germinate a Goldstrum seed after loads of attempts.The latest attempt is vernalising in a rather cross mother in laws fridge as we speak/type.I just look on the bright side.Even if I don't get seedlings it's riled the old goat a bit

If anyone wants rudbeckia seeds, I have lots - the only caveat is that they are old - my Mum stashed seed packets at the back of a kitchen drawer for many years. I'm keeping the ones that expired in 1983 for next year's 'will they grow' experiment.

This time of year is a bit late for cuttings, but root divisions are perfect. Or, start seed now for next year.

That could be rudbeckia Goldstrum, or possibly with that height Rudbeckia Hirta or a variety of helianthus. I've never seen Goldstrums grow that tall before. i have them in my garden and they usually grow about 30-36".

My goldsturm is only 24ins tall -- maybe it is because it is so windy at the plot.

Grew them from cheap plug plants last year
