Legacy Bulbs Seven

On the legacy bulb wiki pages Kathleen Sayce reviews bulbs that outlast their gardeners, with some hints as to why. Suggestions came from PBS list members, review of world weed lists, USDA PLANTS National Database, Flora of North America, and some university databases. For more information consult Legacy Bulbs Index and Introduction.

In North America, this species has naturalized in many eastern states and provinces, from Nova Scotia to Illinois, Missouri, to South Carolina and Louisiana. On the West Coast it is known to have naturalized in Oregon and California. Other states and provinces are to be expected.

Lilium is a large genus of highly desirable garden bulbs, grown for millennia, and very hardy, provided bulbs do not dry out during hot weather. Terrestrial mollusks and viral diseases limit persistence in many locations. While the following summarizes North American populations, expect similar patterns in other temperate growing areas, including Europe, Australia, New Zealand, China and Japan. Like other geophytes, expect to find persistent populations outside currently known locations and species.

Lilium bulbiferum, orange lily, is native to Europe. It produces bulbils in leaf axils; WHZ 7-9. Naturalized populations are known from Eastern Canada and Utah. This lily may persist in much of North America and temperate climates around the world. A PBS member from SE France mentioned it as a carefree plant.

Lilium martagon, Martagon or Turk’s cap lily, is native to central Europe through northern Asia to Mongolia and Korea, and has naturalized in Quebec. It is widely grown in cool winter areas of North America. It may be slow to establish, but is very long lived and can form large clumps; WHZ 3-10.

Lilium philippinense, Philippines lily, has naturalized in Florida. Native to the Philippines, it is tender, zones 9-11, and flowers late in the summer; WHZ 10-11.

Lilium regale, regal lily, has naturalized in Mississippi. A PBS member from SE France mentioned it as a carefree plant. WHZ 3-8, native to western Szechuan, China, the bulbs are hardy, but early shoots may be damaged by frost.
