eryngium neptunes gold. can anyone advise on how to get it to grow ? I bought a 1 year plant early 2015 and it grew very slowly and didn't flower. It's come back this year but the rate of growth is ridiculously slow and I can't see it coming to anything again. Its in a large pot, well drained compost in a sunny position
