This yellow coneflower grows from a rosette of large bluish-green leaves. In late spring, it sends up a sturdy, tall stalk with, way at the top, flowers whose most prominent feature is the dark central conical disk, which juts out further than on most other coneflowers.
||yellow (early summer)
||ordinary garden soil
||germinate at room temperature

We left this plant behind in our Pennsylvania garden (and wish it well); we don't grow it in Houston.

|Susan Borchard||Oct 13, 2004||Hi, I've got to have this. I have giant sunflower seeds from a sunflower over 15 feet tall. Yellow Horn Tree seeds, Fuzzy-Leaved Orange Poppy seeds, Trichostema Lanatum, Persimmon Tree seeds. Would you trade any of those for some of your Giant Coneflower seeds? PLMK @ firstname.lastname@example.org Thank you and what amazing photos and you are a genius. I don't know where you get the time.
Susan (Maybe the genius comment will get me the seeds!) LOL|

|Jackie Adams||Oct 18, 2005||I'm jazzed to try the Rudbeckia Maxima in '06. Any chance this year's yield will be viable? Thanks for the site.|
I'm not too hopeful - I'll be trying for myself, but wouldn't trade until I have more confidence in viability...
|PD Wythe-Mn||Aug 23, 2008||My R. maxima seems to be bi-annual, ie, blooms every other year. I have five plants so far and 3 are dormant this year but they bloomed last year. By dormant, I mean they have basal leaves but no stalks. I assume they are gathering strength this year for next years' extravaganza. Do your plants act this way?|
I've found it difficult to keep them alive past their first year of bloom - which often doesn't arrive till their third year of life. I know they should be longer-lived, so there must be something my garden and I are doing wrong.

|Sheri||Aug 22, 2010||I have had trouble germinating rudbeckia maxima too. I now know that it must be sown fresh. Put a small amount of sharp sand in a jar, add the seeds and then shake it up like a cocktail for 5 minutes. Spread the seed + sand mixture on top of compost and do not cover further. Put all in plastc bag to retain moisture. Seeds are available from Derry Watkins www.specialplants.co.uk|
|Bre'Naysia||Nov 15, 2011||I think this website is the best for looking up the rudbeckia maxima plant!thank you!|
- Seed from '02 trade. Baggy 70F (50%G, 5-16d)
- Seed from '04 garden. Baggy 70F (5%G, 7d). Apparently most of the seeds I collected were duds. Will look harder at the seedheads next year
- Seed from '06 garden. Lots of seeds to a pot at 70F. 1 germinated, in 7d
