Positive MorelCottrill On Jul 31, 2014, MorelCottrill from Dunn, NC (Zone 8a) wrote:

I bought one gloriosa daisy about ten years ago and still have its descendants today. The plants grow as annuals or biennials here, but since they always reseed themselves generously, their lack of longevity is not a problem for me. The large, colorful flowers provide a nice variation-on-a-theme when planted with black-eyed susans.

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 my Gloriosa Daisies. They bloomed in zone 3 from late June to frost. They are blooming when all other plants in my garden have finished.

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.

Decent plant, there are so many of these Rudbeckia that look just a bit different from each other. Flowers lasted a long time.

Positive trois On Apr 26, 2005, trois from Santa Fe, TX (Zone 9b) wrote:

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.
