Rosettes pale green becoming red and yellow in spring.
'Jubilee Tricolor' is a lovely sight in spring when the normally pale green rosettes start to become flushed with red and develop distinctive yellow centres. The rosettes are medium to small in size but produce enough offsets to make good clumps. It makes a lovely specimen in a clay pan, ideal for an alpine house or a cold, well-ventilated porch or conservatory.
A wonderful variety but seldom offered.
Note, April 2018. We have had this plant for about 30 years and have been unable to discover much about it. It certainly isn't common. I now believe it may in fact be one named 'Sunburst'.
'Sunburst' was bred by Mark C. Smith in the UK around 1970 (he also bred 'Rosie' which we also grow) but the name 'Sunburst' was given by Enid Milton in 1977. This name certainly suits it better than 'Jubilee Tricolor'.
There is a plant named 'Jubilee Tricolor' but my research shows it doesn't turn pale green in summer, remaining reddish, when 'Sunburst' always turns pale green in summer, without exception.
It is notriously difficult knowing the correct name of Sempervivums as so many are alike and their histories (source or parentage) are unrecorded. In fact, the major Amercan forum for Semps insists on calling any plant which cannot be accurately identified a NOID. That stands for No ID or no indentification.
