Sart Roloise was created in 2012 by Roland Boulanger in the village of Sart-Eustache, Belgium. The name is a portmanteau — "Sart" from the village, "Roloise" from Roland's name.
Boulanger crossed White Wonder, a creamy ivory beefsteak, with Baby Blue, a variety carrying anthocyanin shoulder genetics. The result was something neither parent could have predicted: a large bicolor fruit with luminous yellow-gold flesh marbled with pink and rose, capped by dusty lavender-blue shoulders that deepen in sunlight.
It took years of selection to stabilize the cross. What Boulanger ended up with is a tomato that combines the tropical sweetness of the best bicolors with an otherworldly appearance — cut one in half and it genuinely looks like stained glass.
The variety built a quiet following among European collectors before making the jump to North American seed catalogs. In 2026, Roger's Gardens and Tomatomania named it Tomato of the Year — a recognition that put Sart Roloise on the map for a much wider audience. It earned that title.
