It makes the most sense to wait until after treatment to send a demand letter so that the demand letter can include a list of injuries and treatments and associated costs. Once the demand letter goes out, it can take a few months to get a settlement offer back. If it is a low-ball offer, then the case will go to court.
Weeping rose trees are 4- to 6-foot standard forms grafted with a spreading ground cover rose such as the Red Meideland rose or the deep pink China Doll. Climbing roses such as the pink Renae take the cascade one step further, often draping close to the ground. Rose trees of 48 and 60 inches are used for this purpose.
Drift roses were developed for use as flowering ground covers. Drift roses (Rosa Drift varieties), generally hardy in U.S. Department of Agriculture plant hardiness zones 4 or 5 through 11, are a series of ground-cover roses designed for versatility in landscape applications. Drift roses are wider than they are tall -- usually about 18 inches tall by 30 inches wide. The plants bloom repeatedly throughout the growing season and are simple to maintain.
