We don't have native trilliums in our ecology so I am unfamiliar with their growth habits.
I purchase four bagged plants (T. grandiflorum) at the local garden center. I was quite surprised that after puting the roots in pots that the plants almost sprang to life and were 3 inches tall with three leaves after just four days. In 2 more days the flower bud has formed (at least I think it's the bud).
I'm curious. How long do trilliums take to flower after they emerge in the Spring? Just a couple weeks? I was hoping to transplant them into the garden in mid April for flowering but will they have finished by then?...if so, not a big deal as we can enjoy them in the house and they'll root fine for next year when they'll emerge late in the season.
Is it just a couple weeks from emerging to flower? Thanks.
