Hi: Does anyone have experience with Dianella revoluta? Does it send up only one round of scapes per year, or does it send up multiple rounds? Thanks for the info.

It can often be found used -- try Amazon and Powell's. The first thing to know is the difference between a true bulb and a corm. Tulips (true bulbs) do not naturally act as you describe. Normally the main bulb persists, unless it has been planted too shallowly, in which case it may produce a "dropper" to get deeper into the soil. I have 10-year-old species tulips still flowering without having increased vegetatively; these probably reproduce in nature mainly by seed.Thanks Jane. I found the book interesting and useful.

I can't really speak to the Tulips as I only grow a few of the species, but for your question on North American Fritillaria, I can recommend the book Bulbs of North America, published by the North American Rock Garden Society 2001. The chapter on Fritillaria discusses bulb offsetting of the American species. You may also find the chapter on Lilies useful.

One nursery in Oregon has offered L. washingtonianum before but it before but it looks to be unavailable on the current list, https://www.sevenoaksnativenursery.com/native-plants/perennials-and-bulbs/lilium-washingtonianum/
My guess they are selling seedlings, it does germinate readily here but the bulbs never seem to gain any size at my low elevation, 620'.
Here is a pic of it in the Oregon Cascades, only an hours drive from my house, and a 20 minute hike to see wonderful populations of it. The fragrance is powerful on warm sunny days in the mountains, it's such a great plant but so hard to grow! I'll plan to make a trip up to this spot to get some seeds for an exchange this season. Maybe someone will unlock the secret.

If you interested I have some small bulbs of Lilium sargentiae.
I'm in New Jersey and grow them outdoors in the summer but put in the cold greenhouse for winters.
