TOMATO ‘KY1’ Vegetable Seeds
Botanical Name: Solanum lycopersicum
- ‘KY1’ is a classic Australian tomato variety bred for hot climates, reliability and heavy cropping.
- Produces medium-sized, round red fruits with firm flesh and excellent flavour for slicing, cooking and preserving.
- Determinate (bush) habit, making it lower maintenance than vine tomatoes and ideal for smaller gardens.
- Uniform fruiting with strong skins and low cracking—perfect for bottling, passata and sauces.
- Performs well in warm, sunny climates and copes better than many heirlooms with heat and humidity.
- Compact plants suitable for garden beds, raised beds and large pots.
