Ratings & Reviews

(Sao Borja Scarlet Sage) Three-inch-long, smokey purple blossoms that bloom from spring to fall are a major clue that this heat-tolerant perennial is not your grandmother's Scarlet Sage.

Even when grown as an annual, Salvia splendens 'Sao Borja' brings a tropical look to any garden by reaching an impressive height of 6 feet or taller in one season.

This Brazilian native grows well in USDA Zones 9 to 11 where it is a tender perennial that may return yearly to the warmest parts of its range. 

Sao Borja was discovered in the port city of Sao Borja, which is named after Spain's Saint Francis Borgia. The city is located on the Uruguay River, across from Argentina and in Rio Grande do Sul, which is the southernmost state of Brazil and borders the Atlantic coast.

To succeed, Sao Borja Scarlet Sage needs partial shade all day or a combination of morning sun and afternoon shade. It also requires rich soil and ample water for a spring surge of growth that needs to be seen to be believed. Use it as a screen, an accent plant or in a container, which will limit size.

Highly recommended.
