What makes plants bloom?

The latest patch for Terraria added in a bunch of new plants (and their seeds) for use in alchemy.

I'd like to make a sustainable farm for these new plants, but I'm having trouble determining when the plants are in bloom.

What are the conditions underwhich the new plants will "bloom", and produce seeds on harvest? An ideal answer would have a picture of each plant in bloom contrasted with a picture of a plant not in bloom.

• Daybloom blooms when it's day time.
• Moonglow blooms when it's night time.
• Blinkroot blooms (and stops blooming) at random.
• Deathweed blooms only during Blood Moons or a full moon.
• Waterleaf blooms when it's raining.
• Fireblossom blooms during sunset. (3:45 PM - 7:30 PM in-game time)
• Shiverthorn just takes time, and doesn't stop blooming once it does.

When blooming, the plants also emit light and/or particle effects.
