Plant Type: Perennials
'Lord Baltimore' is a vigorous, sturdy, erect but somewhat shrubby, woody-based hibiscus cultivar that features dinner plate-sized, 5-petaled, hollyhock-like flowers (to 10" diameter) which are among the largest flowers produced by any perennial that is cold hardy. Crimson red flowers with ruffled, slightly overlapping petals. Each flower has a prominent and showy central staminal column. Individual flowers last only one day, but one or more flowers usually open each day, in succession, over a long mid-summer to early fall bloom period. Lobed, medium green leaves on reddish-brown stems.
Growing & Maintenance Tips:
Easily grown in average, medium to wet soils in full sun. Best in moist, organically rich soils, but does surprisingly well in average garden soils as long as those soils are not allowed to dry out. Regular deep watering is advisable. Tolerates some light shade, but full sun with good air circulation produces best flowers, strongest stems and the best environment for resisting potential diseases. Site in locations protected from wind to minimize risk of wind burn. Deadhead individual flowers to maintain plant appearance. Cut back stems to approximately 3-4" in late autumn. New growth shoots are slow to emerge in spring. However, once new growth begins, it proceeds quite rapidly and plants will benefit from regular fertilization during the growing season.
