My plants have self-sown a fair bit.

Folks who like to arrange may be interested in the dried seed pods.

This is an easy-to-grow lily. Adaptable to harsh conditions. Flowered in about 18 months from seed. The only lily seedling to survive in my unamended clay soil. Subtle scent if your nose is IN the flower. Similar appearance to the regular Easter lilies. Worth growing for it's impressive height alone.

Several years ago I purchased seeds for this plant from the online catalog at Monticello (aka Thomas Jefferson's home). This year, my first "baby" bloomed and I was amazed by its beauty. Though still young, with only one large bloom, it lasted and lasted in our summer heat. I cannot wait for its siblings to bloom next year, and to collect the seeds from this year's bloom. I want more of these in my garden!

I am thrilled to report that I rescued my Formosan/Philipine lily from a nearby bar ditch before the mowers made their cut!
I potted up a good root system & overwintered lily in greenhouse. It bloomed, made a bundle of seeds. These seeds were planted outside greenhouse later and made a beautiful plant loaded with white, Easter Lily like blossoms. So refreshing to have them bloom in the hotest part of summer. July-September 2005.
Try it, you will love it!
Thank you, DG friends, for lovely pictures of your lily!

Easy grower - but gets 7-8 feet tall and needs to be staked. Looks like an Easter Lily on a long pole!

A species lily from Taiwan.

Has deep green, linear to lance shaped leaves. Bears large, trumpet shaped, scented flowers with white petals flushed dark pink/reddish on the outside.

Flowers July - September

Loves a moist but well-drained, neutral to acid soil in sun or light shade. It's not very hardy and may require winter protection in cold regions or grown as a greenhouse plant.
