Rudbeckia fulgida var. Fulgida vs. Rudbeckia Goldrum

summerstar(Z7VA)March 11, 2012

Here's my question: I'm wondering if any of you have grown the Fulgida and the Goldstrum variety and would you tell me what you thought of the differences. I've wanted to purchase the Fulgida variety rather than Goldstrum because Fulgida suppose to be shorter and more compact and longer blooming. I sure would love to grow the plant if it's true, but I'd like to hear reviews from actual growers.

Now before some of you tell me that Fulgida IS a variety of Rudbeckia and that Goldstrum IS a fulgida and there is NO "Rudbeckia fulgida var. Fulgida", let me say that Bluestone Perennials shows Fulgida on page 62 of their 2012 Spring catalog along with Goldstrum and Dave's Garden says two other nursery sites carry it. I checked it out, and yes, there are two nurseries selling Fulgida. But is the plant shorter, more compact and longer blooming? I'd like to know.

I grew Goldstrum and found it's large leaves soak up so much sun in my Zone 7, full-sun garden that it wilted by noon every day. It was also well over 30 inches high and not at all compact. I DID love the flowers though. They draw your eye even from a distance. Thanks much.

Some say the species (fulgida) is less prone to septoria leaf spot than Goldsturm. Personally I have not had a problem with either. Rudbeckia fulgida 'Early Bird Gold' is a little smaller growing to about 2ft. with slightly smaller blooms. I THINK the leaves may be a little smaller as well. It's supposed to be day neutral and start blooming up to two months earlier. That has not been the case for me, it starts less than a week earlier here.

I've found Rud' f. fulgida to bloom ealier and longer than Goldstrum. It's not quite as tall or broad and the flowers are a little smaller and a little more yellow. Also, I found that it performed better in a partially shaded site.

As always, keep in mind that the same plant in different sites/zones/sub-climates/conditions/soil, etc. will perform differently, but I hope this information is helpful.

I happen to love fulgida fulgida.

Best of luck!

Just to emphasize the correct name - it's Rudbeckia "Goldsturm" (German for "Storm of Gold"), NOT "Goldstrum" (sellers often screw this up for some reason).

Thanks everyone for sharing your experience with these two varieties and also for a correction on the spelling of "Goldsturm".

Last week I found another short compact rudbeckia variety of Black-eyed Susan that I'm excited about. I'll post here with a description for those interested.
