There are over 100 species of the rose. Because they're low-maintenance and nice to look at, rose shrubs are used as landscape plants for hedging (the thorns can discourage intruders) or planted on hillsides as a slope stabilizing method to stop soil erosion. We usually call the sharp spikes on the stem of a rose bush "thorns". But these are in fact technically prickles. The flowers of most species of rose have five petals except for the species 'Rosa sericea' which has only four.
For hundreds of years the rose has been widely recognized as a symbol of love, sympathy or sorrow. Take a moment to relax and smell the roses, as you search for this cache.
