Trillium

here is a close up taken today of the ripple ice-cream Trillium rivale petal

Nice pics Mark.
I remember Michaels wonderful shots of various Trillium rivale forms on the old forum including a plant named T.rivale roseum AGM form.(Had a quick look and found the postings under Trilliums 05).

Paul--Michael very graciously offered ,via the forum ,seed off some of his plants and i was lucky enough to receive a envelope in june 05.Seed was sown immediately and although i don't remember any germination the following spring there has been great success this past season .Fingers crossed......

Cheers Dave.

Dave,

Yes, I remember said seed.  In fact I think I had good germination last year from those he so generously shared.  Like I would miss an opportunity like THAT!!? <grin>  I know that Michael's were pretty speccy, but one can only hope for something as lovely that the "ripple ice cream" colouration as Mark so aptly puts it.  Thanks for the closeup Mark.  Really lovely!!  Are you going to self cross it and try for seed, or else cross it with something as close as you have in colouration?  Who knows what seedlings you could end up with out of that in a few years time?

Actually Dave you've reminded me that I must check on that pot.  I'm tempted to pot the whole thing up into a larger pot to give them a chance to put on some size.  I am figuring that not all have germinated as yet, given that they can wait a while (although not as much as the Trilliums themselves).

Such a nice thread....... reminds me so much of what is to come.  More Crocus starting to poke up buds here at the moment, plus more of the autumn Galanthus.  Great Stuff!!

as for seeds of these ripple Trilliums there will be no seed from them this year as I have crossed them all with T. ovatum. There will be next year.

Mark,

So how will you know whether you have had them self or that the cross was successful?  Did you emasculate the flowers early on, and were there other rivales flowering within bee distance (or did you screen it off to be sure)?  I am wondering as I figure that if seed sets in this case you'd really be wondering, given that so many supposed crosses have ended up being selfs or straight rivale instead.

Despite all that gloom and doom from me.... good luck with the cross.  I can wait an extra year to see what your rivale seedlings from this look like.  I reckon you'll eventually be showing us a whole range of different ripple ice-cream offspring for us to drool over (and maybe even if you're lucky some ovatum x ripple ice-cream offspring as well! <grin>).

this is the first year I have done the cross after reading about in on the PBS forum. I suppose it may be three years before I know what will happen. I didnt remove the anthers - didnt think about it - but did add ovatum pollen before the anthers were ripe. The pot was then isolated on the north side of the house

I didn't think rivale would hybridise with ovatum?

Trillium` Del Norte' Reputed to be a hybrid between T.ovatum and T.rivale.  It looks like a giant T.rivale and clumps up fast.  Totally awesome.

Trillium cuneatum in flower at the moment looks good in dappled shade.

Three trilliums I have open now are T. rivale; T. pusillum and T. grandiflorum forma roseum. This is my best form, although it has been pinker.

 In response to a scent feature: I would say yes to some, but to others I would say no. Foetidissimum is properly named. Its scent has been likened to Limburger cheese, which I am sure someone must find pleasant, or more like really bad stinky feet. Erectum is like a wet dog or egg white. Reliquum is bad, but not quite sure what to call it. Others are acetic or rotten fruit like, but many are intensely sweet. Some cuneatum, luteum, most discolor (some are peppery with lemon), Florida lancifolium, and albidum are all pleasantly scented.

 As for T. rivale, I wish I grew it. I have two pots of seed. Sitting & waiting. Someday they should germinate.

Here are some of my ovatums, native to my yard, which I have crossed
with T. rivale pollen I collected in the Siskiyous.  They are caged to protect
them from deer, which relish trilliums.

I chose pollen from varied rivales - it is amazing how much they vary, even
ones very close to each other may be white unspotted, pink or red spotted, pink,
round-petalled, folded-petal-tips, plain or white-veined leaves - take all
those variables and mix them.

I'm sure if I do get ovatum/rivale hybrids I will be able to tell because my
ovatum are plain white with plain green leaves.

I'm happy to hear that Mark is doing the recipocal cross for me.

Here are pictures of some of the Trillium rivale growing near each other
in the Illinois River Valley in southern Oregon in the Siskiyou Mountains.

I will probably have to put them in several messages as ones showing
habitat have a lot of pixels, but I think it is interesting to see how they
are spaced, and what grows with them.  You will notice leaves of
Erythronium citrinum, which emerges later than the trillium.

As you can see from the litter, they grow under widely-spaced pine trees
with manzanita ( an Arctostaphylos).  The ones growing in an adjacent
more-thickly wooded area, with Arbutus and Douglas fir (A. menziesii and
Pseudotsuga m.), were often nipped off by deer.  The deer apparently did
not like dining in the open pine areas.

In no case, despite what many books say, have I ever found them near
a stream.
