Simasalabim is one of the most beautiful and attention grabbing roses that there is. The rose is highly variable as evidenced by the photos posted on HMF. The plant has the unwelcomed habit of reverting back to its Frisco origin as a pure yellow rose. I grow 4 of the numerous manifestations of Frisco. It seems that Simsalabim is the most mildew prone. In our clime it needs constant protection against powdery but it is well worth the effort. It is not a rose recommended for those adverse to spraying, although a bush covered with powdery will occasionally produce those eye popping blooms. The rose poses a conundrum for exhibitors as at least one authoritive source classifies the rose as a hybrid tea which it is not. The rose is a classic miniflora as we know the class. The ARS should declare that all roses which are primary, secondary and tertiary sports of Frisco be classified as minifloras for exhibition purposes. This group of roses is too important and interesting to be denied a rightful place in our rose shows. Nuff said!

I also did research on Simsalabim. I have wanted it forever and could never get my hands on it.
The word is Scandinavian in origin. Appeared in a America in the 1900 used in a magic show, by a magician named Dante.
And yes Sim Sala Bim = Abracadabra.

Funny I had some thought about how much Simsalabim pictures looked like my Abracadabra!
Thank you Kim for bringing this up.
