Roses are my favorite flower they are a very pretty woody perennial flower. 
Oh I love roses! Especially on Valentine's day. What's a perennial flower?
Perennial flower is just the plant from which the rose was originated from and especially valentines day only thing the cost be so high around that holiday for roses. 
Ahh yes. Roses can be quite expensive on Valentine's day. The only thing I don't like about roses are the thorns.
Yes the roses are full of sharp prickles but when out buying them from stores they should be thorn free.
I wondered why the ones I bought from the store didn't have any thorns. Are there any thornless roses?
No they are all full of thorns being they are in the wild and on trails and people climbing close to them that's their way of being protected to grow in the wild without being properly grown is my best guess lol.
Interesting! I didn't know that roses could grow in the wild. Are they native to a specific region?
, North America, and northwestern Africa. Species, cultivars and hybrids are all widely grown for their beauty and often are fragrant. Roses have acquired cultural significance in many societies. Rose plants range in size from compact, miniature roses, to climbers that can reach seven meters in height. Different species hybridize easily, and this has been used in the development of the wide range of garden roses.
Etymology.
The name "rose" comes from French, itself from Latin "rosa", which was perhaps borrowed
