  • While selecting from my crosses of S. 'Fat Jack' this year I've been surprised at how few wide-leaf seedlings were produced. This plant was one of my first wide leaved cultivars so I used it in crosses a lot in 2019 and have somewhere in the ballpark of 100 seedlings from protected handcrosses alone. About 75 of them are from a big cross to 'Silver song' where only a few seedlings surpass either parent in leaf width or surface wax, I'll only hang on to 3 out of the hundred just to see if another generation can bring out the width. It is a fertile plant, much more so than its parent 'Rita Jane', but if leaf width is a goal for you as a hybridizer I'd suggest just fighting the uphill battle with 'Rita Jane's limited fertility, you'll get 1/10th the seedlings, but they'll be 10 times as wide.
  • This lovely sempervivum produces a number of sports. Care must be taken to remove them from your colony to keep the cultivar correct. The sports should not be shared or sold as 'Drop Rockoon'.
  • Erwin Geiger said:Most red hybrids actually reach their color peak through their spring coloration. While the medium-sized rosettes of our random seedling are still painted with a dull crimson at this time, it will shine from your bed in very striking shades of red from July to September. A valuable addition to the large selection of Sempervivum hybrids.
  • Erwin Geiger said:A vigorous selection of the generative offspring of 'Tarita'. From an ergonomic point of view, the arrangement of the medium-sized leaves is reminiscent of roses at first glance. They appear all year round in the most different, bluish violet and purple with olive green pastel mixed with some ochre. Here it is also worth remembering the popular name "stone rose" for the genus Sempervivum, which was given to it by Karl Foerster.
  • Hans-Jorg Gensch said:'Alstergraffiti' attracted attention in 2015 due to its completely washed-out colours. After three years, it became stable in burgundy, with bright tips. But the Kindel retain their mottled play of colors.
