Outrageously spiky but the overall look of these can only be described as pretty. Beautiful even. From a distance : fluffy. They look good in little groves of different sizes. They tend to sucker so you can easily end up with this look anyway. Removal of old, yellow and bent leaves is vital to maintain this prettiness. Without maintenance they will look nothing of the sort. Not good in windy sites. The leaves are not particularly flexible and once they're bent (they fold), they must be removed. They form a nice straight trunk and branch after flowering.
In common with all the yuccas we grow : remove old leaves (pull off or cut off, depending on your proclivities), use fungicide on them if they get spotty (this will stop the spot spreading not make the spots go away), they have large white flower spikes in late summer, they branch after flowering, remove the flower spike as soon as the flowers fade. Any reasonably well drained soil - they're not desert plants and are not as fussy as people often imagine.
These are from suckers from Italy. Native to the Carolinas, U.S.A.
Some notes about spotty leaves : some plants (this is one) are susceptible to getting black spots on their leaves. This is the growth of fungal organisms that land on the leaf and grow. They do no harm to the plant but they look unsightly. This spottiness only seems to afflict a small number of plants that have spent the last few million years evolving in a dry climate where airborne fungal spores are rare and therefore the plants have never had a reason to develop a way to combat the situation. The technique to combat these spots is a combination of fungicide (any will do - particularly anything recommended for roses) used when the spots appear and merely removing (and burning preferably) affected leaves. Leaf removal removes the source of infection, fungicide kills the spores (but doesn't make the spots go away).

General Point about Plant Hardiness: The commonly held belief that it's better to 'plant small' is perfectly true with herbaceous plants, but not necessarily true with woody plants. They need some 'wood' on them to survive severe cold - so plants of marginal hardiness in very cold areas should really be planted LARGER, rather than smaller, wherever possible.
