Yellow Fireworks is an excellent tomato created by the Canadian breeder Stanley Zubrowski.
Yellow Fireworks has almost perfectly round, bright yellow tennis ball-sized tomatoes (120 g to 200 g/4oz to 7oz). Not a crack or blemish on the fruits. And it tastes wonderfully sweet. The plants are a compact 2 ft tall and easy to manage.
A bit more about Stanley’s plant breeding work:
Although he is more well-known for his clematis varieties, Stanley has also developed some wonderful tomatoes. Yellow Fireworks is his yellow selection of Tim Peters’ red tomato, Fireworks. Tim Peters is another master tomato breeder whose tomatoes we like (see the description for ‘Winter Gold’ in Longkeepers).
Stanley first listed Yellow Fireworks in his 1998 seed catalogue for his former seed company, Saskaberia Seed & Nursery, located in Prairie River, Saskatchewan.
In 1997, Stanley was awarded the D.R. Robinson Award from the Saskatchewan Horticultural Association for his plant breeding work, which puts him in the select company of several other important Canadian plant breeders, such as Bert Porter and Percy Wright.
In 2026, Stanley celebrated his 81th birthday — and he continues to create new tomato varieties. We are excited to see what he comes up with next!
We’ve been fortunate to get to know Stanley over the years and recently interviewed him about his breeding work. You can read our interview with Stanley HERE
