I am having trouble finding information on the Chamaecyparis lawsoniana 'Summer Snow',
I would be most grateful if anyone could enlighten me to afew of its features;
-Its growth rate
-Any functional contributions it would add to a small rockery
-Does it flower and if so what are they like
-maintenance issues ie. pruning
-Is it susceptible to pests or diseases??

Any help would be grately appreciated,

Thanks :o)

Very, very slow growth rate. Good for a rockery. As with all conifers, the flowers are insignificant. Conifers are not grown for their flowers. No pruning required but can be shaped should you do desire. Not particularly prone to pest problems. You would get more information from the Conifer folks.
