Answer: They are talking about the same plant. Moonflower vine is long lived in a warm climate but grown as an annual in colder areas. It does not tolerate frost. It requires a warm soil and a full sun position as well as a long growing season to do its best. In partial sun and a cooler climate such as yours as it might not bloom until late August or even later! And its blooms will be relatively sparse. It may self seed in a favorable spot and seem to be perennial in your area for that reason, just as some patches of morning glories do. It might be worth an experiment if you really want to grow it. Otherwise, you might try a clematis with white flowers in a partially shaded spot for a blooming vine but without the fragrance. For information about ordering, please contact Burpee directly.
