    The Woodland Sage should be watered deeply once a week, ensuring the soil is moist but not waterlogged. In hotter, drier climates, the frequency may increase to twice a week. It's important to avoid overhead watering to prevent mildew and other diseases, so aim to water at the base of the plant. Use about 1 gallon of water per plant each time, adjusting slightly depending on soil conditions and weather. Allow the top inch of soil to dry out before watering again to promote healthy root growth.

  • sunLight

    The Woodland Sage thrives in full sun to partial shade. It is best to plant it in a location where it will receive at least 6 hours of direct sunlight each day. However, in extremely hot climates, some afternoon shade can be beneficial to prevent scorching of the leaves.

  • circleLife cycle

    Salvia × sylvestris Blue Marvel = 'Balsalarv' (PBR), commonly known as 'Blue Marvel' Sage, begins its life cycle with seed germination, typically in early spring, in a soil mix that offers good drainage and warmth. Upon germination, the seedlings grow rapidly, developing a rosette of leaves and a root system. As temperatures rise in late spring to early summer, the plant begins its vegetative growth stage, producing strong stems and abundant foliage. During this period, flower buds develop, leading to the blooming stage where vibrant blue flowers open, attracting pollinators and lasting from late spring to fall. After pollination, the plant may set seed, though as a patented hybrid, it might not reproduce true to type from seed. The plant enters dormancy in late fall to winter, during which above-ground growth dies back, with the root system surviving to regenerate the next spring.

      Spring to Summer

    • The Salvia × sylvestris Blue Marvel, commonly known as Meadow Sage 'Blue Marvel', is typically propagated by softwood cuttings. This is an effective and popular method which can be done in late spring or early summer when new growth is tender but has not yet matured. Cuttings should be about 2 to 4 inches (5 to 10 centimeters) long, taken just below a node. It's important to strip the leaves from the lower half of the cutting and perhaps dip the cut end into a rooting hormone powder or solution for better chances of success. The cuttings can then be placed in a well-draining soil mix and kept consistently moist. Enclosing the potted cuttings in a plastic bag or covering with a plastic dome can help maintain humidity levels, thereby encouraging root development. It usually takes a few weeks for roots to establish, after which the new plants can be gradually acclimated to less humid conditions and eventually planted out.
