Sounds like daylily (Hemerocallis.)

Hard to tell what you have because lots of people refer to the wild tall daylilies as tiger lilies or ditch lilies. I don't know how to make clickable but this site has a pic of those: http://www.gardenersnet.com/bulbs/tigerlily.htm
Here is one of the lily versions: http://davesgarden.com/pf/go/1025/

The common orange daylily is pod sterile, no seed. I bet it's the bubils from the tiger lily.

I got day lily seed to grow! Yes many or even most of the seeds might be duds, but some do grow. I started some last summer and they are coming back strong this spring. I am expecting them to bloom. I have no idea what color.

The way to tell real tiger lillies from the ordinary orange day lilly ( both grow wild ) is the tigers have spots and many blooms on one stalk. The wild orange day lilies do not.

I think I read that both lilies spread both by roots and by seeds. It takes years for the seed to grow and produce a bloom but it does happen.

There are different kinds of daylilies. Hemerocallis fulva is pod and pollen sterile. It doesn't produce seed. Can't produce seed. It reproduces by underground runners, stolons.

I do a little daylily hybridizing and it takes about 2 years for regular daylilies from seed unless your in a warm place like Florida or Southern Cal.

I bought a Yellow colored tiger lily plant from walmart and I want to know how to take care of it. I read few columns about viruses and spreading to my other plants. How does it actually affect other plants? Is it through ground? As I have seperated the tiger lily plant from other plants(my other plants r not lilies). Further, I don't see anymore new buds and the old flowers are drying up. Do I need to do anything for my plant to bloom new flowers?. Any advice is welcome. Thanks in advance!!!

shrav - there's a good chance that your tigers are not infected. As I understand, not all are, however as they say, "YMMV" (your mileage may vary), mainly because the tigers will show no symptoms of any disease. The virus that they can carry can cause color break in tulips and if I recall correctly, can be transmitted via insects - eg., aphids.

The plant you bought is a bit early in its bloom - but then that tends to happen if you buy them already potted and blooming. Once the main stem comes up it will hit a certain height and produce a certain number of flowers running along that stem, and then that's it for the season. You would then leave the stem and its foliage in place the rest of the summer as this is what will "feed" the bulb.

Once the stem turns brown and can almost be snapped off manually with the lightest of tugs, you can remove that dead stem and discard. But you want to try to hold onto that stem and foliage as long as possible as this will help increase the size of the bulb.

The bulbils (small black things) are not seeds, but miniature bulbs. They produce identical new lilies to the mother plant. Seeds and bulbils are vastly different.

To sortof continue Ken's comments above, if you plant those little bulbils in late summer/fall, the babies will put up a single leaf that following spring, and those single leaves will persist through the summer.

The spring after that, they'll each have a few more leaves and even a tiny stem (which is what my little babies are doing at the moment).

This was the mama plant:

So is there any special way to save the bulbs? I have alot of those lilies in front of my house and I would like to plant them elsewhere too. Do I just need to keep them dry?

Don't let them dry out. Let the bubils (small black spheres) stay on the lily plant until after flowering at which time you can remove them and plant them shallowly in loose, well draining garden soil. The bulbils will turn into flowering lilies in 2-3 years.

I sowed some seeds last year around mother's day. nothing came up. about a month ago, i noticed some green poking up from the soil. no idea what they were b/c i planted so much last year. well, i watched as they grew and they are the tiger lilies i sowed last year. i thought the seeds didn't take, but i have a bunch of bulbs now.the problem now is that their growth has halted.hope i answered your question. good luck

I am encouraging wild tiger lilies to form a barrier between my lawn and an adjoining field.

At what time of year do the lilies put out their new shoots ?

So that I don't keep inadvertently mowing down the new shoots.

THANK YOU !!!
