Positive Reynardine On Jan 26, 2013, Reynardine from Lake Helen, FL wrote:

I brought a slip of this plant home from an empty lot in Cassadaga in 1996, knowing only that this was some kind of rose. But this is Sleeping Beauty's rose, the White Rose of Heraldry, ferocious, indomitable, quite nearly everblooming. Shy of fragrance, when she releases it, it is the scent of southern magnolia, and the flowers themselves are magnolias in miniature. The local race clothes the young canes and new rosebuds in pale green velvet- and in the velvet gloves, what steel claws! I call her The Dominatrix, and that she is. I am happy to have her...I just wish I had planted her in a whiskey barrel or something...

Neutral bettydee On Aug 3, 2005, bettydee from La Grange, TX (Zone 8b) wrote:

This evergreen rose has some positive as well as negative traits. Introduced from China to England in 1793. It has naturalized and thrives in southeastern U.S., growing from Virginia to Florida to Texas. The 2 - 3" white 5 -petaled flower is slightly fragrant. The pistils are surrounded by several hundred golden stamen, an outstanding combination. The leaves are divided into 7 - 9 leaflets. This distinguishes it from a similar looking rose: Cherokee Rose, Rosa laevigata, which has 3 leaflets. The vicious thorns are strong. This rose can be very invasive and is difficult to get rid of. Like other members of the rose family, such as dewberries, and blackberries, this rose will resprout from root sections left in the ground. There are a few hybrids of this rose.
