Ask Mr. Smarty Plants

Although there are some small native wildflowers with the word "jasmine" in one of their common names, we suspect you are interested in Jasminum polyanthum, a "true" jasmine as described in this Floridata article and sometimes referred to as winter jasmine. Or you might be thinking of Tracheospermum jasminoides, from another Floridata site. Some common names of this plant are Confederate jasmine, or star jasmine. Both are natives to China and both are hardy from USDA Plant Hardiness Zones 8 to 11. Salt Lake City is in approximately Zone 5b, so neither plant could be grown there year-round.

That is about as much information as we can give you. The Lady Bird Johnson Wildflower Center is dedicated to the growth, protection and propagation of plants native not only to North America but to the area in which they are being grown. We are assuming that the main attraction of these flowers for your wedding is their wonderful fragrance. Your best bet is to locate a local florist, and keep calling until you find one who at least has some suggestions. We have no connections with nor information about florists. We deal with the plant itself, usually as a part of landscaping or land restoration. Most flowers from florists are non-natives, so you could find one who could either provide you with jasmine cuttings, or suggest other flowers comparable in size, color and fragrance as you requested.
