Frost damage(?) to 'Ulla'

This spring I have experienced frost damage to two of the flowering shoots of my ‘Ulla’ plants. Although many Cyps are quoted in the literature as being frost hardy this normally refers to the dormant plants ability to withstand low temperatures. The two plants featured started to grow in my cold shaded, greenhouse and I moved them outside to experience normal weather conditions. We had several nights with temperatures of minus 3 to 5°C resulting in the shoots being marked and perhaps a little distorted by the frost. A third plant remained under glass and is fine. The flower buds have now started to rot inside so I will cut out the damage and spray with fungicide. A nearby plant of parviflorum was not damaged.
