Trillium rivale

First year bloom on Trillium rivale:

Seed sown January 2007, germinated Spring 2008. To keep the voles out, I plunged the pot into the garden soil and mulched. The plants seem to do very well. They eventually grow roots through the drainage holes and into the surrounding soil.

Very impressive !! 

And that each plant flowers so uniformly is a feat indeed!

Gene, I have read that it takes many years to get flowers on Trillium so I have not bothered sowing seed. But now you give me hope and I'll look out for fresh Trillium seed to try!

Hoy, most Trilliums are much slower to bloom than T. rivale.

Very nice Gene, and just 4 years from seed to get that potful of blooming plants!

I grow lots of trilliums from seed, but I sow fresh seed directly in the garden as soon as the seed is ripe in late summer. They germinate freely the following spring and one can forget about caring for them, and slowly but surely they get bigger each year.  I believe I get first flowering on T. nivale in about 4 years too, others typically take 5 years or more.

Trillium rivale in now in a seperate genus (Pseudotrillium) with it being the only species within it. The new name is Pseudotrillium rivale. That might be one reason it flowers a faster rate than most Trillium.

Here is my Pseudotrillium rivale (pink flower form) just starting to open up.

Albany, Oregon USA. Pacific Northwest, elevation approximately 200ft zone 8. Winter wet and Summer Dry. Hot enough to ripen the peaches.

James, It's a beautiful Trillium.  I don't afford much credence to the "pseudonym" Pseudotrillium, seems like taxonomists these days must garner some pseudofame with such taxonomic contrivances.  I still await the day when they take a genus like Allium and split it into about 80 or more genera; there are allium species that "break the rules" of the genus all over the place.  In fact, with Allium, the opposite force is in effect, with strong centrifugal action pulling in genera like Nectaroscordum and Caloscordum into the allium vortex.

A couple of good links (note, most web links will still refer to this plant as Trillium rivale).  The CalPhotos gallery shows some beautiful color forms.  Looking at them, if these aren't trillium then I'm a monkey's uncle ;)  The ongoing Flora of North America still publishes Trillium rivale, not Pseudotrillium.

I still refer to it as Trillium as well but it is native here and I live real close to Oregon State Uni. where they did the genetics makeup on it. I was just giving a possible reason why it only took  a short time to flower from seed rather than the 7-10 like many trillium (that is all and I am a name Freak  ;D)

They are especially nice with the spots (or rather, flecks) of deep color.
