Gladiolus callianthus These showy pure white flowers with startling maroon throats are nothing like the ordinary garden gladioli. Blooming in mid-summer to a height of 3 ft., they are a show piece for any garden. Be sure to plant along a pathway or near a sitting area because the added bonus of this flower is its intense perfume. For optimal growth, give them full sun and excellent drainage.
