Sure plant them right away. They take a long time to bloom and you may run out of season, but they won't be any good next year, so get them in the ground as soon as possible. Al

Those bulbs don't last longer then one year?

It's not too late to plant; I potted mine up last year beginning of June and they bloomed later in Aug. Your season is a lot longer than mine so you should have no problem. And yes these are easy to save year to year.

Okay....so then the bulbs I have will be okay to plant next year?

As much as I'd like to plant them now, I'd rather be able to enjoy them all summer then just a couple weeks in september. September depresses me because the season is over....lol

No. You have to plant them this year. They won't hold over to next year.

Even when planted in spring, these are a late flowering plant. They won't bloom all summer.

Mine are blooming right now! As are my other glads.

However I planted some glads this time two years ago and they bloomed in August.
