On the other hand, my Trumpet and Asiatic keep on multiplying.
Orienpet also is doing fine, but multiplies much more slowly than Trumpet and Aisiatic.

I live just west of Minneapolis, MN. Orientals are more picky regarding needs compared to most other hybrid lilies, but if they get what they want, they are long lived. While most hybrid lilies prefer neutral to slightly acid soils, they are somewhat tolerant of somewhat alkaline soils, which are certain death for orientals, which prefer acid soils and are usually tolerant of neutral soils. In a similar manner, orientals are not as tolerant of summer heat extremes as other hybrids are. Oriental lilies also require better soil drainage than most other hybrids. Hybrid oriental lilies are easier to grow than oriental species in general, yet I grow 3 species orientals here without problems: L. speciosum var. rubrum (6 yrs), L. speciosum var. album (4 yrs), L. auratum (3 yrs).

Black Beauty is a hybrid of oriental lily and asiatic lily (L. speciosum var. rubrum x L. henryi) and is much easier to grow, and hardier. Mine has been thriving and multiplying for 10 years.

Are trumpets as hardy and reproductive as asiatics?

And how slow reproductive and how hardy are orienpets?

The only orienpet I have is 'Silk Road':

I planted 9 bulbs 3 years ago. This year I saw 10 shoots whereas my trumpets usually double or triple every year. Asiatics make a lot of new bulbils every year.

If Tiger lily you mean is this:

Then it is very hardy and long lived. It blooms when my trumpets begin to fade and right before L. speciosum. And it makes a lot of black bulbils along the stem. Quite prolific and gives a lot of oomph to the garden in summer.

I have different lilies in my garden to prolong the blooming season. I have lilies in bloom from late May though August. Right now my L. speciosum Rubrum is in bloom. They flop, though, because they get only an hour or so of mid-day sun.
They would stand up straight in full sun.

The amount of flowers and first time blooming depends on the age & size of the bulbs you plant. Some types are smaller than others when mature. Most likely yours didn't flower because they weren't mature enough. Make sure to feed them good and let them die back before cutting stems to build reserves for next years show.
Generally Asiatics multiply the quickest, followed by LA hybrids, Orientpets, Trumpets, Orientals with Martagons taking years. Hence, the higher price for Martagon bulbs vs Asiatics.
Also, some bulbs like to sulk more than others, not coming up for a year or so after planting......this is a common trait of the Martagon.
Enjoyed the lovely pics from pitimpinai.

If the bulbs are large, they usually bloom the first year, if you plant in early spring, the following spring-summer if you plant them in fall.

Tiger lily from tiny bulbils will take a few years to bloom.
But, boy, it's worth the wait.

Yes, My 'Silk Road' bloomed the first year. I bought the bulbs from The Lily Garden. It is the most expensive lily I have ever purchased other than Martagon, but the bulbs were huge - as big as my fist. Silk Road is about 6 ft. tall. :-D

I kind of remember hearing something about they start growing too deep - has anyone tried to dig them up and replant them a bit shallower? Just an idea.
