Ah, a week of cold rainy weather will discourage any gardener. Very depressing! When the sun comes out and things start jumping up from all that water, you will feel better. Your lily looks promising already.
I am originally from Vancouver, Canada. Another place where it rains, and rains and rains! You have my heartfelt sympathy. (that's the reason I now live in Florida - I'll take the risk of hurricanes any day over cold, rainy weather for days and weeks)
It sounds like you've learned a lot and are still working at it. Plus you have many more hardy perennials than you did the last time I saw a picture of your garden.
By the way, next fall when you dig your tender bulbs, clean them off and dust with a little bit of anti-fungal powder. This will prevent the majority of the fungal woes, both during the winter and in spring if it's wet again. It's probably the reason they didn't rot on you the first year - the grower most likely dusted them before selling. OR Another trick is to plant them in dark colored pots, then sink the pots a little bit into the soil where you want the plants to grow and hide the pot with some mulch. Then when it's time to rescue them before winter, you just need to let them die back, and lift the pot. I have many tropical " "divas" that I protect in winter this way. (we do get some cold nights in January and I can keep them from going dormant with just a little protection)
