I would guess sometime July? I think it depends a little on the size of the bulbs, the larger corms will bloom sooner, smaller ones will take longer. Have patience, if the leaves are tall and healthy already then it should just be a matter of time before you have flowers.

Do you know the variety? There are early, mid, and late season ones. Pinetree Gardens has a guide on their glad page that might help you figure out roughly when they'll bloom. Maybe your variety is listed there. This link should take you directly to their glad page. If that doesn't work, just go to www.superseeds.com and head for the "items for spring delivery"

Here is a link that might be useful: Pinetree glads

Yay! Guess what? I found the package they came in. They are "blue passion blend" and bloom mid-summer....does that mean more than likely July?

Dear Vela... Expect blooms SOON! Mine just started, I have many spikes of white, purple and pink. I live in the SouthEast US

I had read that glads flower 80-90 days after planting the bulbs. You can stagger the planting of the bulbs to get a longer glad display.

I'm in Zone 8a and mine just finished blooming :(
Pretty early but its been 90-100 here so...
