This plant wintersows very well. My wintersown ones started blooming around July and, though fading now, are still in bloom in mid October. I am collecting seeds to wintersow again next year.

I love the color of this Rudbeckia. I did not do well in a spot that got more shade than sun. I reseeded itself, which I love! It also wintersows very well.

These plants have been a joy. They have bloomed continuously for the last two years, even last Christmas when covered with snow.
Six of these plants are sprouting their seeds while still in the flower head, and many others are spreading all over the flower beds. They are a very attractive and colorful plant.

They give a big splash of colour in your garden and in a vase for a long time. I've deadheaded regulary and cut them down a little by placing lots of them in a vase.

I love the colors in this plant! Best treated as a short lived perennial, as they don't seem to endure for many seasons. They tend to have a powdery mildew problem, so make sure there is good air circulation and the foliage does not stay damp.
That said, the beautiful bronze flowers are just wonderful in a garden where there are too many pinks and purples. A big plus at my house.

My experience is different. I grew several of these from seed last year (2003) and they had grown to about four inches by Easter 2004. I planted them in my garden in France and did nothing to them, other than give them an automated watering every two days
for 20 minutes.
When I returned in late July, they were as shown...
It could be that they are best grown as biennials.

This is my second year with these. Although I love the color the plant does not generally make it past mid July. I have a variety of other Rudbeckia's and Coneflowers and this one perplexes me. I have grown it both in containers and in the ground and it does not matter where they are. I will not grow it again.
