This is one part in a weekly series featuring the UC Davis Arboretum’s “Garden Gems” series – 45 can’t-fail, easy-care, low-water plants well adapted to our region and that add sparkle to drought-tolerant landscapes.
Giant silver mullein
Size: Starts small with low mound of large leaves first year, up to 1 foot tall and 2 to 3 feet wide.
Bloom season: White and yellow flower stalks in second summer.
Exposure: Full sun.
Pruning needs: None.
Water needs: Low to medium water; once established, water deeply every other week.
Snapshot: This eye-catching and unusual plant rewards patience; it takes two years for this beautiful biennial to bloom. Native to Turkey, silver mullein starts out with large, white furry leaves that form neat low-growing rosettes. During its second summer, silver mullein shoots out narrow vertical wands of white and yellow flowers, up to 6 feet tall. The flowers attract butterflies and hummingbirds. Another plus: Deer won’t eat it! After that big bloom, mullein dies to the ground, but it will reseed around the garden, assuring more mulleins to come.
