The idea that a Cypress (coniferous) could also be a hardwood is absolute nonsense!
Linnaeus will be turning in his grave!
Pecky= fungal attack, leaving the voids that are shown
Hardwood= some of the trees lose their foliage in Autumn and hence, behave in a Deciduous way.
It is in effect a rotten softwood, only available in the US.
Some holey Yew might work well for this sort of thing.
