What is the difference between Salvia greggii and Salvia microphylla?

Salvia greggii and Salvia microphylla are both sage plants, but they differ. Salvia greggii is a woody shrub with fragrant, tubular flowers, typically red, pink, or orange. Salvia microphylla is also a shrub, but it has smaller leaves and produces tiny, brightly colored flowers in shades of blue, purple, or pink. Both species are drought-tolerant and attractive to pollinators, making them popular choices for garden landscapes.

What is the best soil for Salvia greggii?

Salvia greggii thrives in well-draining soil that is rich in organic matter. A soil pH between 6.0 and 7.0 is ideal. Adding compost or other organic matter to the ground can help improve its fertility and moisture-retention capabilities. The soil should be kept consistently moist but not soggy, which can lead to root rot. Salvia greggii is also tolerant of a wide range of soil types, including sandy, loamy, and clay soils, as long as the soil is well-draining. It is important to note that Salvia greggii is drought-tolerant but requires regular watering, especially during extended periods of hot, dry weather.

How tall does Salvia Mirage Deep Purple get?

Salvia Mirage Deep Purple is a compact, shrubby plant that typically grows to a height of 12-18 inches, with a spread of up to 24 inches. It is a cultivar of Salvia microphylla and is prized for its vibrant, deep purple flowers and attractive, aromatic foliage. The plant produces numerous spikes of flowers that bloom from late spring to early fall, attracting pollinators to the garden. Because of its compact size, Salvia Mirage Deep Purple is an excellent choice for borders, rock gardens, or containers. It is also well-suited for an accent plant in mixed borders or specimen plant in a garden bed.
