Trees that don't bud-break easily

Does anyone know of a list of fruit varieties that don't break their buds easily?  The issue is warm spells mid-winter, followed by freezing weather, in addition to the usual late-spring frost concerns.

You might look into trees with especially high 'chill hours'

Thanks -- that might be easier to find than looking for hard to get bud-break.  Terminology is everything (and I know I've seen chill-hour lists).

Mullberry. Pomegranate.  

Will pomegranates grow in Kentucky?  (I suspect not.)  But mulberries will, and I was already planning on planting some of those around the outside of the goat pasture.

Our pomegranates are usually the first to break bud and set fruit.  Our variety is "Wonderful" --- it seems to do great even when we only get 100 chill hours, as we did this past winter.

Apples, on the other hand, don't seem to want to get the message that spring has sprung and it's time to get rolling.  With the exception of "Anna", all my other varieties are slow to jump into action (Dorset Golden, Cripps Pink, Fuji, Gala).

See, those apples that don't break bud early are what I'm looking for.

I don't know about its budding habits, but I know Honeycrisp tends to bloom quite late.

I've got a weird situation here. I'm going to be moving into a new house soon, so last year I planted lots of things in containers, I planted mulberry seeds, and got two little trees in nice tall 15 liter container. They were in my solar greenhouse for the winter, and then I moved all the containers outside in march when the greenhouse was getting too hot. Now the smaller mulberry tree in the container has leafed out already for at least 2 weeks, but the larger one in the same container hasn't, though the twigs and buds look alive.

What do you think, will it leaf out several weeks later than its container-mate?
