Prayer for the Blessing of Roses

From the Dominican Breviary and used today on the Feast of Our Lady of the Most Holy Rosary:

"Our help is in the name of the Lord...
Who made heaven and earth.

The Lord be with you.
And also with you.

Let us pray.
O God, Creator and Preserver of the human race, who grant us the Holy Spirit with His seven-fold gifts, and who generously bestow eternal salvation:

Sanctify, we pray, and bless these roses.
We present them before You today, and seek Your blessing upon them, to express our thanks to You, and our devotion towards the blessed Ever-Virgin Mary and her Rosary.

You created these roses as a source of pleasant fragrance and gave them to us to lift our spirits. Then through the power of the holy Cross pour out upon them Your heavenly blessing.

Signed by the holy Cross may they receive so powerful a blessing that in the houses and hospitals where they are taken the sick may be healed. From the places where they are kept may the powers of evil flee in fear and terror, nor may they presume again to disturb Your servants.

We ask this through Christ our Lord.
Amen."
