I planted this Jessamine two years ago. It is on the southeast side of the house and growing up a porch post. It grows very quickly and I have had to prune it a little to keep it in bounds. It flowers heavily in spring and smells wonderful. At the other end of the porch I have clematis montana "rubens" and after one finishes most of its bloom the other takes over. It doesn't seem to mind too much rain in the winter and spring and then too little rain in the summer and fall. It just keeps growing and has not had any die back from winter. This plant is very hardy here and I would imagine would still work well in colder climates.

I have had one of these in the ground for going on 3 years now. I checked the hardiness before I purchased it, but it doesn't seem to like Portland Oregon. It looks shabby by spring, this year nearly leafless, it takes all summer for it to leaf out properly and it's only had one blossom in 3 years.

I've grown this plant for several years and not even a leaf has been frost-damaged. I can't believe that isn't more widely grown. If you live in zone 6, don't hesitate trying this lovely plant.

I am experimenting survivability with this cultivar this year. Anyone had any success in zone 5b/6a? I expect it to die to the ground and come back as a perennial vine each year.

This plant is an abundant bloomer, blooming several times a season.

I live in NE San Antonio, and have had this plant for almost ten years. It is planted on the North corner of my backyard, and has climbed up to my roof, and I have stringers going to side and along back of house. In third week of Feb. it blooms like CRAZY!! And I am a bit stunned that it is budding right now, Mid Oct. and already has some blooms...(???) I have lots of seed pods, but have not taken much time to get any going. Ones have dropped to the ground, and start off but it seems slow growing. Thanks for reading!

Grew this plant in Huntington Beach, CA. Beautiful yellow flowers in Spring, then whispy light green folage the rest of the year. A very fast grower. Temperature was approx. 40 to 90 degrees and it was in afternoon sun. Needs to be supported, gets to 15-20 ft, if you let it.

This cultivar of gelsemium sempervirens was one of the 2005 Gold Medal Plant Winners of the Pennsylvania Horticultural Society. It was chosen in part for its superior sized, fragrant yellow flowers, and in part for its cold-hardiness. According to hgtv.com, this cultivar has survived a -25 F cold spell with no damage.

It is a versatile vine and is adaptable to many soil conditions, but some in the southern United States consider it invasive.

Update:

Margarita finishes its first season outside in Bucyrus, Ohio with no appreciable winter damage. Our coldest temperature was 0 Fahrenheit, but this vine stayed evergreen. There was no defoliation. I'd expect this to be root hardy even if the top of the vine were killed. 0 Fahrenheit doesn't phaze it, though.
