Trillium Rhizomes not sprouting

pandora(Z5 OH)

I bought some Trilliums and they came as root cuttings. They looked healthy. I potted them up in a tray, watered and kept in unheated garage about 12 days until temps didn't go below 40 at night. Then put them outside in semi shaded area with row cover protection.

It's been over 2 weeks and only 3 sprouts of 12. Should I continue as is or should I put them under grow lights? I am concerned that the soil has stayed fairly wet without drying due to spring showers.

I did carefully uncover one and the rhizome looked good and solid.

What do you suggest?

What can you do, but wait.If they weren't prechilled, they may not grow this season at all.

I ordered them from a company, so I imagine they were stored in a cooler in the bag of peat moss. I just wondered if I put them inside under my grow lights, the warmth might keep them from rotting and encourage growth.

I have several from previous years that are blooming great dispite the ground they are in is wet. But I bought those as plants, not root cuttings like I received this time.

One of my typical responses. Trilliums (and every other plant pretty much) grew somewhere where there were no humans to cart them in and outside. Let them be a plant and grow in the ground.

:) Kind of like Occam's razor or keep it simple. You are probably right. Thanks for the advice and taking the time to help out a fellow gardener.

I bought some (possibly shady) some years back. They had already sprouted and rotted (foliage) in storage, so did not grow the first year, but I have quite a few now. Sadly I have only spotted two species though (luteum and pusillum). I wish the mix had included some red and whites..but at least they're getting bigger and better each year and have interesting leaves.
