One flower makes no garland. [ English Proverb, collected by George Herbert ]

All flowers are not in one garland. [ Proverb ]

Sweet pillows, sweetest bed;
A chamber deaf to noise, and blind to light;
A rosy garland, and a weary head. [ Sir Philip Sidney ]

For thee, O now a silent soul, my brother,
Take at my hands this garland and farewell,
Thin is the leaf, and chill the wintry smell,
And chill the solemn earth, a fatal mother. [ Swinburne ]

In eastern lands they talk in flowers, and they tell in a garland their loves and cares. [ Percival ]

Where confidence is wanting, the most beautiful flower in the garland of love is missing. [ Goethe ]
