That is so cool! Congrats on having these repeat so strongly! I especially love the fluffy white one with hints of purple.
Your lovely gardens look fairly well established, been around for a while. Do you use a lot of organic matter, mulch, compost, leaves? I do believe cover on top helps a lot, but don't think the increased drainage that occurs in an area over time from repeated applications of OM gets enough credit for helping create a microclimate, and zone-pushing in general. It's rained so much here this summer, one of mine looks like it has rotted to death. Wish I'd realized sooner in time to lift the bulb, bummer. But of course I was inside because of all of the rain. I've taken a few cuttings that still look great, perky, flowers still blooming since this past Friday. Hope they make roots! It's a twin to your one on the left on the bottom row above.
