Answer: It's hard to leave behind your cherished garden favorites when you relocate, but then you have the adventure of finding new ones. Fortunately, there are species of both butterfly bush and lilac that will grow in the Las Vegas climate. Chinese lilac (Syringa chinensis) prefers mild winters and hot summers, and both Buddleia alternafolia and B. davidii are at home there, so long as they receive adequate moisture. Lily of the valley doesn't grow well there, but you can try forcing them indoors in winter.
Check out your local nurseries for planting stock best adapted to the conditions, speak with nurserypeople, and contact area Master Gardeners http://www.extension.unr.edu/south/mgarden/
