usually get intermittent frosts, frost at night but above freezing during
the day, or they only last a couple of days, whereas they can get frosts
that last for weeks, day and night.
Another example of our Maritime type climate against their Continental type
climate perhaps.

There are many different species of yucca, only a few of which can be grown outdoors in the UK.
The maritime vs continental issue often goes the other way on plants like this. Some plants can survive heavy frosts provided it is dry enough, or provided it then warms nicely up in the day, or provided they have been well ripened by a hot summer preceding, or all three. For example, many cacti, yuccas, agaves, aloes, and the like grow in desert mountains where the temperature regularly falls to -10 at night in winter, which is also the dry season. But they would just rot in our damp winters.
