How to grow Nightfall in Botany Manor

Nightfall is one of four unique flowers you'll encounter in Chapter 4. Unlike most plants, it won't bloom with just sunlight and water. The key lies in the attic, where a mysterious projector awaits. To activate it and coax Nightfall into bloom, you'll need to decipher a specific color code: blue, yellow, orange, and red.

Unraveling the Nightfall's secret unfolds like a manor-wide puzzle. Your exploration will lead you to the library, where you'll need to solve the symbol puzzle to unlock a hidden door.  This hidden chamber holds valuable clues, including the Fairy Painting and the Fairy Story.  These elements, along with the Attic Key found near the Brook Chalice clues, will become instrumental later.

The attic itself holds its own set of secrets. Look out for the Moth Poster and Calendar – seemingly random at first glance, but crucial for deciphering the color code. The calendar depicts the Garden Tiger Moth, hinting at its significance around September.  Additionally, the secret room in the library showcases Sunset Paintings that, upon closer inspection, reveal the colors of a September sunset – blue, yellow, orange, and red.  This connection between the moth and the sunset paintings starts to solidify the color sequence.

With the color code in mind, you can finally focus on Nightfall itself. Locate a Nightfall seed (available after solving the library puzzle) and plant it in a pot with soil. The attic, with its projector, becomes the flower's designated growing area. Water the seed and position the potted Nightfall in front of the projector.

The moment of truth arrives! Locate the red button and press it to activate the projector. As the colored lights bathe Nightfall, witness the flower blossom in a vibrant display.  Congratulations! You've successfully cultivated this unique bloom.
