The supermarket has introduced into selected branches Coeur de Boeuf and yellow beef tomatoes - the first time either have been widely available for several years.
The Coeur de Boeuf tomato is known for its flavour and its unusual ox-heart shape. With its low moisture and largely hollow interior, the Italian variety is often stuffed and cooked or used in pastas and sauces.
Yellow beef tomatoes are known for their high juice juice content, soft texture and a distinctive fruity flavour and are more typically served fresh.
Both are grown for the supermarket by Wight Salads. The yellow beef tomatoes will be priced at £4.59 per kg, while Coeur de Boeuf tomatoes are being sold individually, priced at £4.99 per kg.
The supermarket has also rolled out its pink blush tomatoes, introduced last year, to 235 branches following sales "way beyond expectations", it said, while its golden baby plum tomato is in twice as many branches this year.
Waitrose now sells 30 tomato varieties in all. Its tomato buyer Peter Cooke said: "Our customers' appetite for new and exciting varieties shows no sign of abating."
The upmarket retailer is also launching an economy 1kg bulk mixed selection pack made up of round, cherry and baby plum tomatoes which have either naturally fallen off the vine or are misshapen, priced at £2.99.
