Cereus
Cereus are a group of cacti from North and South America and blooming now at Baltimore's Rawlings Conservatory in Druid Hill Park.
They can reach 30 feet in height and are columnar shaped. In late spring or early summer they flower in colors of light pink, yellow, or white. Blossoms can grow up to 8 inches long.
One of the most interesting members of this species is the Peniocereus greggii or the night blooming cereus which will grow a beautiful and fragrant flower.
They will only bloom at night and unfortunately only last for one evening.
