I always look forward to my Chatham Island forget-me-not to flower.. It is a pretty special plant and not easy to grow, for once our exposed spot with salty coastal winds actually work in my favour.
The Chathams are 800 Km East of the South Island and very exposed. https://www.rnzih.org.nz/RNZIH_Journal/Pages_2-3_from_2014_Vol17_No2.pdf
