I have to disagree with this, at least from the viewpoint of a region (the foothills of the Pacific Northwest Cascades) that gets much more frost than David's does. Here, winter frost is frequent, and it doesn't melt at all in certain shaded areas, and not until afternoon in others. I have a good colony of the marginally hardy Muscari macrocarpum in a very well drained raised bed where the winter sun does not reach until midday. Thus, its winter-growing foliage (which is also likely to be very moist here) is frozen for quite a while during cold weather, but it thaws very slowly because the day warms before the sun hits it. Antoine Hoog and I corresponded a little about this plant, which he finds is not winter-hardy for him near Amsterdam, and he agreed that its partly shaded site at my place may protect it to some extent. My plants flower well in early spring despite the beating they take from the cold of midwinter. Another hint is to plant marginal bulbs under open-growing shrubs, which afford some frost protection. The warmest spot in my hilly garden is a west-facing rather steep slope, which receives no morning sun; here I can grow camellias, evergreen kniphofias, and some Californian and South American shrubs that have not survived in other exposures.
