Salvia karwinskii 'Red Form'

Rated: 

(Karwinski's Sage) From moist mountain areas in Mexico and Central America, this rugged, winter-blooming shrub is found in oak or pine forests at altitudes of 4,000 to 8,000 feet. This may account for this winter bloomer's ability to produce some bright, brick-red flowers even during short periods of freezing weather with temperatures as low as 20 degrees F.

This is the non-scientific name used for a plant. A plant may have several common names, depending on the gardener's location. To further confuse the matter, a common name may be shared by several completely different plants. At Flowers by the Sea, we rely on the scientific name to identify our plants and avoid confusion.

Exposure
This is the average amount of sunlight that a plant needs to thrive. Generally, full sun exposure is 6 or more hours of direct sun daily while partial shade is less than 4 hours of sun or dappled shade all day. Plants may tolerate more sunlight in cooler climates and need afternoon shade in extremely hot climates.
Full sun to partial shade
Soil type
This is the kind of soil that a plant needs to thrive. Most plants require a well-drained soil that allows the water to soak into the soil without becoming soggy. Sandy and clay soils can be improved by digging in compost to improve drainage.
Well drained
Water needs
Plants have specific water requirements. Water loving means the plant needs regular watering to keep the soil moist. Average generally indicates applying 1 inch of water per week, or watering when the soil is dry to a depth of 3 to 4 inches. One inch of water is equal to 5 gallons per square yard of soil surface.

(Karwinski's Sage) From moist mountain areas in Mexico and Central America, this rugged, winter-blooming shrub is found in oak or pine forests at altitudes of 4,000 to 8,000 feet. This may account for this winter bloomer's ability to produce some bright, brick-red flowers even during short periods of freezing weather with temperatures as low as 20 degrees F.

Speaking of color, the reds of Karwinski's Sage vary, but hummingbirds love them all. This variety was originally collected by the San Francisco Botanical Garden.

The plant's leaves are pebbly and large -- up to 6 inches long -- with cream-colored hairs on the underside. Size is another dramatic aspect of this plant, which can grow up to 10 feet tall and 4 feet wide. Due to this generous size, it helps to plant Karwinski's Sage in a spot where it is protected against chill and winds. A south-facing wall is ideal. It makes a good screen or background planting, but can also be grown in a large patio container.

To encourage upright, compact growth, periodically remove some of the flowering branches. Or you can prune the plant down to a few active growth nodes once a year at the end of its winter flowering season when it appears there will be no more frost.

This sage is named for German botanist Baron Wilhelm Friedrich Karwinski von Karvin who explored Mexico in the early 19th century.
