Well, I must say my first encounter with Nerine was a walk into one of the side roads and it was baking hot, must be 32c and suddenly, I saw this whole line of pink flowers coming out of half buried bulbs - they were like some ballerinas. This has borne out what you say about half-buried bulbs. I said to myself. I must have some of these as there were tons of flowers and concrete on both sides of this line of plants. They were literally being cooked in between the road and the paved front garden. I reckoned if they were that happy in the "baking tray", they would surely do well in my garden. But no, for the last two years, I have been waiting and waiting and waiting, and my heart bleeds whenever I see them dancing beautifully outside some houses. Ah, I know what to do. I might move some of them to the kerb next to the pavement. The trouble is that alstroemerias and irises have already staked their claims... But worth a try..
