Very small, its diameter is no more than 10 mm.
Leptospermim scoparium cv. Possibly cv. Nicholsonii or a hybrid derived from it.
You know to much Peter! I am only guessing but it looks similar to the red flowered, manuka cultivar Leptospermum scoparium 'Red Ensign' which looks like it is based off a version of Leptospermum scoparium 'Nicholsonii'.
LOL. Well I did do my PhD on this section of the Myrtaceae..........
Thank Peter and Andre.
