This appears as a bright yellow open cone and is ready for pollination. For ‘beef’ tomatoes, 3-5 flowers should be allowed to develop on a healthy truss Mature flower
These are denoted by the appearance of bruises on the anther cone left by bumble bees clamping onto and pollinating the flower Fertilized flower
