Saint Andrew's Day just passed, end of November. Brother of Saint Peter, Saint Andrew is the National Patron Saint of Scotland.
Saint Andrew is said to have been martyred on a cross shaped like the letter X after asking that he not die on the same kind of Cross as Jesus died. This diagonal cross is called a saltire when used as a heraldic symbol. Scotland's national flag is a white saltire on a blue ground.
Hypericum hypericoides is a native plant here. The blooms have that distinctive saltire shape.
Summer blooming from July to September, pics above are from September.
Blooms are followed by reddish brown seeds in November.
Bird planted, a few plants are allowed to remain in a bed of Azaleas under dry Oak Shade. In spring they are cut back to the ground for a little better shaped plant, which stays under 4 feet tall.
