Each time that Lifebloom is cast on a target, the Lifebloom stack is incremented by 1 up to a maximum stack of 3. The entire stack shares a single expiration timer, which is refreshed to max duration every time Lifebloom is recast on the target. Therefore, a single casting of Lifebloom is sufficient to maintain an entire 3-stack.
The heal over time portion for this spell ticks every second.
The HoT is enhanced by 9.5% of your spell power per stack per tick. The bloom is enhanced by 64.6% of your spell power.
Critical effects from the bloom cannot proc Living Seed or Nature's Grace.

Stacking and maintaining 3 Lifeblooms on a target provides a reasonable amount of healing every second.

Also very useful in PvP; players that can dispel Magic-type buffs will have to decide whether to leave the Lifebloom buff on (they continue to receive healing, then they'll get a chunk of health back), or to dispel it (in which case the target will get the final healing effect right away). One of the best mind-games a Druid can play in PvP.

Hotfix (2009-04-16): "Lifebloom can no longer be forced to bloom early. ^[1]"
Patch 3.1.0 (2009-04-14): Mana cost of all ranks doubled. When Lifebloom blooms or is dispelled, it now refunds half the base mana cost of the spell per application of Lifebloom, and the heal effect is multiplied by the number of applications.
Patch 2.4.0 (2008-03-25): The spell coefficient on the bloom is reduced by 20% (from approx 42% to approx 34%). The talent Empowered Rejuvenation now applies to the bloom.
Patch 2.3.2 (2008-01-08): The healing bonus is no longer based on the first cast but will take on the strength of the incoming Lifebloom casts.
Patch 2.1.0 (2007-05-22): Each additional application of this spell will now include the full bonus from effects which increase healing. The final heal, however, is still unaffected by stacking multiple applications of this spell.
