#1 we need for you to tell us what zone you live in.
#2 if you want something to grow fast, don't start with seed. It will take years. Buy bulbs!
#3 Bulbs bloom as different times i.e. asiatics first, trumpets next, etc.
#4 number of blooms depends on the age/size of the bulb. You get what you pay for. Generally the smaller the bulb, the younger the plant, therefore not as many blooms as the same bulb that has been in the ground for 3 years.
Tell us more!

Hi, I really do not care if it grows fast or slow. But if species asiatics exist please let me know.

thanks

The parents of the asiatic hybrids include: amabile, cernuum, concolor, davidii & pumilum. All of these are easy from seed, though cernuum needs a little more care. If people in your area are successful with hybrids, these should do OK.

Thanks. Could lillies aso be grown as houseplants. Thank you all for your contributions.

Lilies need a few months of 30-40 degree chilling every year to leaf out in the spring and produce new blooms. So, they are not usually grown as house plants. (They also need more sun than can generally be gotten indoors.) lilies are however often bought as potted plants already in bud (the nursery did the chilling) and displayed indoors until their bloom is over. They are then either planted outside to come back the next year or discarded.

There are Trumpet lilies that MAY bloom their second season after being grown from seed (usually with only a single bloom). But they generally take a few years to get growing and blooming well. Regale and Leucanthum are two species trumpets that grow pretty quickly. The only asiatics I've grown from seed are Cernuum and Pumilum, and the seedlings did not do well at all for me. Kaymans caution is correct, you have to baby Cernuum more than other lilies, and possibly Pumilum as well, (these two are close relatives).

"you have to baby Cernuum more than other lilies, and possibly Pumilum as well"

Aim for a dryish summer dormancy with good drainage. That's one reason (apart from the small stature) that pumilum is often recommended as a rock garden plant.
