I regularly take photographs of the plants in my garden - hubby thinks I'm slightly obsessive and he may be right - but as well as being lovely to look back on during the cold, dark, dreich winter, I find that it's a great tool to remembering seasonal plants such as spring bulbs - their location and how they looked together and with surrounding plants. As my garden is only a couple of years old it's also a great reminder of the work I put in to start it, and how my carefully thought out plant purchases (and some spur of the moment 'must haves') have fared and developed.
