| I am so confused. I thought my black eyed susan was a perennial. I have been reading it is a biennial or short-lived perennial. ? ? My black eyed susans are beautiful and full and the clumps seem to get larger each year. However I do have some of the large green leaves with no blooms. Perhaps these are new plants that will bloom next years. Anyway I am so confused. So my question is is it a perennial or biennia? I read that it can be divided. So if a biennial why would you divide it? And why would I cut it back in winter if its going die after blooming? |

| Black-eyed Susan is a common name applied to several species of Rudbeckia (among other plants). It is most often used with Rudbeckia fulgida, which is fully perennial. Confusingly, it is also sometimes applied to Rudbeckia hirta, which is most often biennial or a very short-lived perennial. Once again a situation where common names confuse the heck out of folks!! :-) |

| That's odd, I've never heard Rudbeckia referred to as 'Black Eyed Susan' but rather an annual vine is known to me as 'Black Eyed Susan. |
Here is a link that might be useful: Thunbergia

| I just planted some Rudbeckia fulgida 'Goldstrum' which were sold to me as a perennial, with a common name of Black Eyed Susan's. I planted them where they get lots of afternoon sum. I enhanced the soil with one part peat moss to two parts soil, with some compost thrown in. Now they are wilting in the late afternoon, but perky in the AM. Wondering if this is normal? I hate to water them every day, for fear of over watering. |

| Rudbeckia fulgida 'Goldstrum' is a perennial. It is one of the toughest perennials in my experience, and one of my favorites summer/late summer long bloomers. And they do self seed so you may see a few more plants next year, and so on. So give it some space if you want to have more of them. And they add so much color and life to the late summer garden.They do like afternoon sun! If they are perky in the AM, you do not need to water them. For the first 4-6 weeks after planting, give it a good watering ~ once or twice/week (depending upon temp, rain, etc). If they do not perk up if the AM, water them. After first year, you typically do not need water any more. This year during the long, hot and dry late June and July, I watered them a couple times, that is all I did for the entire summer. |
