Trillium rivale

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!

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.

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.

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

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

Seconded ;D

Beautiful!

Trillium rivale grows well on the west side of the Cascade Mtns.  It is a very satisfying plant to grow because it sets lots of seed and comes into bloom fairly quickly.  I've planted many bunches out in the garden and also grow them in pots on the north side of my house.  Here are a couple of pictures of potted plants.  Many of these are going in the plant sale for the 2012 WWSW in Everett, WA.

Claire...I am planning on attending that event as I have lots of family out your way! Hope to see you there and bring home a few of those lovely Trillium!

What's a WWSW?

WWSW = NARGS "Western Winter Study Weekend".  Each year NARGS also holds the compliment "Eastern Winter Study Weekend".
