First year growing this , Major Wheeler , Magnifica , and Dropmore Scarlet . I know they take a few years to their full glory like clematis so hopefully they thrive and bring lots off hummingbirds my way ! Looking forward to this little guy adding its own flair to my garden! I am keeping my fingers crossed that it is disease resistant here in the south . Native honeysuckles are so much more beautiful to me than their Asian cousins I just wish they were fragrant .

I planted this as a teeny tiny rooted cutting I took off a plant I found growing at the beach rental we were staying 3 years ago. As you can see from my pictures, it is doing wonderfully! It is nearly 5 feet tall as of early spring this year and has dozens and dozens of new shoots coming in. I'm hoping it will cover our shed in a few years. Stays full green and lush all year round, blooms profusely into spring and early summer, then will have a few blossoms on it all year round. My hummingbirds LOVE this plant. I'm now looking for the red variety to add to my honeysuckle collection.

This honeysuckle gets full sun and we have naturally sandy soil as we live on the banks of the Savannah River, which it really seems to appreciate. I've grown other varieties of honeysuck... read more

In Oct 07 I planted this honeysuckle in my Arkansas mountain garden, on a fence facing due west. The plantlet rose above the soil only 10 inches or so. I watered it through the winter, and it almost completely defoliated. In late March 08 I started giving it diluted splashes of 12-12-12 every 3 weeks. Now, it is at the top of the 5 foot fence and looks as though it will thrive. Yesterday (21May 08) a tiny cluster of blooms opened for the first time. Hummmm...the color is a buff-cream rather than a true yellow; as I love true yellow I am hoping that the color will firm-up as the plant matures. Foliage is a nice deep green with a touch of blue.
