That is astonishing Chris. That is the best grown helenae I have seen. I wish I knew your secret to growing these. I haven't found them that easy to grow.
I agree with Migrant as well. I've never seen one so large
and so well-grown. The two I have are doing well, but
seem very slow growers. Ah well, someday...maybe.
I give it a lot of light all year round. Temperature is max 25°C in summer and cool in winter (min 8-10 °C). It is potted in a mix of Orchiata and limestone. Fertilizer is 15-10-15 (0.2-0.5g/l every second week) and some organic fertilizers. Hope this helps.
