Gardeners' Notes:

Negative bmckew On Apr 21, 2012, bmckew from Moravian Falls, NC wrote:

No other rose in my garden has blackspot except this one. I think the blackspot appeared at the same time the first leaves showed. Beautiful color, but it is not resistant to blackspot in this area.

Love the fire engine red color and clusters of medium size blooms that hold up well to wind and rain, but my plant came down with a bad case of blackspot within a couple weeks of purchase. Definitely not resistant.

I bought two showbiz rosebushes about seven years ago or so. They survived and bloomed, but overall their performance was not great. They definitely didn't thrive. The roses they do put out are a very pretty color, granted. But there are way better choices, in my experience. I live in Southeast Texas, in a Houston suburb.

Love, love, LOVE my Showbiz rose. Got it at Home Depot in bloom, and it hasn't stopped exploding with color ever since. Beautifully shaped, fire engine red, semi-double blooms with a yellow center. People come out of the street to ask me what it is, and I have 20 other rose varieties nearby, but that's the one that gets the attention. Very fragrant, and gorgeous in cut arrangements. I have read that Showbiz is extremely disease and blackspot resistant. I haven't had any issues with anything so far.

From's list of carefree roses by Mary C. Weaver:

'Showbiz': Not for the shy, retiring garden, this red, red rose makes a terrific visual impact in the landscape. A floribunda introduced in 1981, 'Showbiz' produces medium-sized, semidouble intense-scarlet flowers with a hint of orange, blooming in large sprays. Repeat is reliable and rapid, for a shrub that's constantly in bloom. The semiglossy, disease-resistant foliage is very dark green, for an appealing contrast with the blooms. 'Showbiz' won an AARS award in 1985. Hardy to Zone 5. Compact and bushy, reaching a height of around 3 feet.
