| THE ROSE FAMILY | |||||||||
| The rose family is one of the most
well known plant families in Saskatchewan. Plants in this family are trees,
shrubs or herbs. The shrubs or trees are commonly armed with prickles or
spines. The leaves can be simple or compound and frequently have a saw-toothed
margin. A pair of stipules is usually present at the base of the stem leaves.
The flowers are in various types of clusters or can be solitary. The flowers
are frequently brightly coloured and showy. The flowers have five sepals
and petals, five to many stamens in whorls and one to many fused or distinct
carpels. The fruits can be drupes (ex. cherry), pomes (ex. apple), or aggregates
of achenes (ex. strawberry), pods, or drupelets (ex. raspberry). Many fruit crops are members of the rose family. Cherry, apple, pear, raspberry and strawberry are examples. Roses are used for medicine and for their essential oils. Many roses are grown as ornamentals in gardens. |
