Look at these cool yellow tomatoes! They are called "Yellow Cropper", they are heritage seeds from the Koanga Institute.
There are also stripey tomatoes called Guernsey Island that are very very delicious.
I grew them from their "Tomato - 3 Colour Mix" (you can get Koanga Institute's heritage seeds from NZ garden centres or order them online).
The Koanga Institute was started by Kay Baxter, who wanted to preserve old seed lines that had been grown and cultivated in NZ for many years - brought with settlers as their most treasured family possessions, gumdiggers, etc. Also there are diverse varieties of and colours of Maori veggies such as kumara. (Nowadays you just find very few varieties compared to in the past.) Tomatoes you buy in the grocery store must last longer on the shelf - so they've been selected for long-lastingness or their looks. My tomatoes that sprouted from these seeds were tasteless compared with the Koanga seed varieties. They can be eaten from your garden fresh, so delicousness can be their dominant trait!
