Just a quick one. Several years ago I planted four or five snowdrop bulbs. Just bogstandard pretty, single, white snowdrops, For some years they faithfully came up, just where I planted them. Last year there were more, still close by.
This year they are all over the middle bed, not thickly clustered, but give them a few years and they will be. How they have spread is beyond me. Have they secretly been digging underground tunnels? Have the teenagers been leaving home to work elsewhere in the bed? Who knows? But they're extremely pretty and a very welcome sight in these dreary winter months.
