Gardeners' Notes:


On Feb 8, 2014, Rickwebb from Downingtown, PA wrote:

This is the mother species that does not spread by underground rhizomes like 'Goldstrum'. It does self sow a lot which can be a blessing or not, depending. It blooms in mid-August into early October in the North.

I like this better than the cultivar "Goldstrum". It is resistant to powdery mildew and the leaves do not turn patchy (black). The habit of the plant is more graceful than "Goldsturm". It needs staking , however. Cat's cradle staking works well.

I grow this in hard clay soil in sun/part shade. It grows very well there and I don't find it invasive at all. I grow it with Purple Coneflowers and other perennials. A classic.

Imagine my surprise when this 2 ft. tall by 2 ft. wide beauty popped up in my tiny driveway bed this March (fullsun/slightly sheltered/southside). It came from a cheap wildflower mix tossed there last spring and had virtually no water to speak of. I'll be curious how it tolerates our hot, dry NM summer and whether it is perennial or annual -but as of today 6/15/05 it has been the joy of my garden.

We grow cv "Goldsturm" which does not have the bad habits referred to by some people above. I suspect some of them are just looking at the English name and not the species, and are probably referring to a different plant. According to Gray's Manual of Botany R. fulgida does not occur in New England, although other species do. Ours have the long narrow petals shown in wannadanc's picture. Gives glowing, golden fall colour.

This flower is by far one of my favorites. I purchased two plants at a local nursery, and now 3 years later I have about 12 of them. Makes a great border, it does not spread to quickly but sure enough if you look around where your other ones were last year you will see a few babies sticking up out of the ground. Its very easy to grow, and seems to grow wherever I plant it.


On Oct 19, 2003, hotlanta from Lilburn, GA (Zone 8a) wrote:

This black-eyed susan makes an excellent ground cover for banks. It is not a very fast spreader, but each year the area is a little larger than the previous. The color is beautiful when in full bloom and the flowers last a month or more. I will be trying to propagate by seed, which I have not done before. Time will tell.


On Aug 9, 2003, Ladyfern from Jeffersonville, IN (Zone 6a) wrote:

Very attractive plant with large, smooth, dark green leaves. Mine grows 38" tall. Blooms second year from seed. The cultivar 'Goldsturn' produces little seeds that are useless to the birds, so plant other cultivars to benefit the birds.

A common wild flower in New England. If you bring it into your wild flower garden, and change your mind, it's the "dickens" to get rid of. Self-sown seeds will sprout for years after parents are gone. Great for kids; guaranteed to flower, and lots to pick for vases in the house. But check carefully for critters!

We love the way that this brightly colored plant grows and looks on our rocky hillside - very hardy here in our mouintains. Does well with just rain water; very self-sufficient & reliable. Have not had any problem with invasiveness. Makes a great vase bloom; combines well with other perennials. Bloom lasts a LONG time!


On May 6, 2002, lupinelover from Grove City, OH (Zone 6a) wrote:

This plant grows enormously big within a year, with new crowns appearing all season. Self-seeds to a point considered to be invasive. Plant should be placed no closer than 4' from the nearest neighbor.

Root system is thick and fleshy, making it difficult to dislodge.

Unlike Rudbeckia hirta, this species is not susceptible to powdery mildew.


On Nov 6, 2000, jody from MD &, VA (Zone 7b) wrote:

This species of Rudbeckia contains the most common grown 'Goldsturm'. It grows to about 2' tall and has lancelote leaves. The flowers are daisy like, yellow with brown cone centers. Best cultivated in sun to part shade. Can propage by seed or division. Hardy zones 3-9.
