Crinum<\/em> spp.<\/h2>\n

With large, showy flowers and a sweetly spicy scent, crinum lilies (Crinum<\/em> spp.) are sensational for adding dramatic flair to many garden settings!<\/p>\n

Each bulb offers two or three successive flower scapes, and each scape is topped in generous umbels that develop handsome trumpet-shaped blooms.<\/p>\n

Colors are mostly in reddish tones such as apricot, burgundy, mauve, pink, scarlet, and white.<\/p>\n

While each flower has a short life of only a couple of days, mature bulbs produce heavily laden umbels that bloom for weeks!<\/p>\n

Tough and low-maintenance, the robust bulbs develop large roots that regularly produce offsets, creating impressive stands of glossy green strappy foliage with multiple flower scapes.<\/p>\n

Plants are long-lived perennials in mild climates, and when grown undisturbed, can last for generations. Some develop jumbo-sized bulbs that weigh as much as 20 pounds!<\/p>\n

Outside of their hardiness range, crinum lilies can be enjoyed in large containers and moved into a sheltered spot protected from winter cold.<\/p>\n

Taxonomy<\/strong><\/h3>\n

Order:<\/strong> Asparagales<\/p>\n

Family:<\/strong> Amaryllidaceae<\/p>\n

Genus:<\/strong> Crinum<\/em><\/em><\/p>\n

Species:<\/strong> Americanum<\/em>,<\/em> x amibile<\/em>, asiaticum<\/em>, bulbispermum<\/em>,<\/em>\u00a0x powellii<\/em>, mooreii<\/em><\/em><\/p>\n<\/div>\n<\/div>\n<\/div>\n<\/div>\n<\/div>\n<\/div>\n

The spreading clumps of long, lush foliage spread two to seven feet and scapes reach three to four feet tall, depending on the variety.<\/p>\n

Many species and cultivars sport large, funnel-like blooms. However, some varieties like the spider lily (C. asiaticum<\/em>) feature distinctively thin, wispy petals.<\/p>\n

Hardy in Zones 7 to 11, all varieties thrive in full sun to partial shade and are highly adaptable to a range of soil conditions.<\/p>\n

As the bulbs grow they also spread via offsets or \u201cpups,\u201d reliably developing into robust clumps with decent drought tolerance.<\/p>\n

Exuding laid back elegance, crinum lilies are dependable garden performers that add eye-catching appeal to beds, borders, and containers or massed into drifts.<\/p>\n

And they\u2019re a stellar choice for erosion control on banks or hills with the boisterous bulbs and large roots perfect for soil stabilization.<\/p>\n

Some species, including varieties of the popular starry-flowered\u00a0native swamp lily (C. americanum<\/em>), are well-suited for growth in aquatic locations with still waters or wet soil conditions, such as bogs, creek banks, marshes, pond edges, and swamps.<\/p>\n<\/div>\n
