LEGO Wednesday Black Dahlia Flower (76784)
✓ Product data checked October 23, 2026
Built from 358 pieces, this LEGO set recreates a black dahlia display from the Wednesday series: dark blooms, purple buds and leaves set in a vase shaped like a small greenhouse. Lift the flower and the vase opens onto Professor Thornhill's secret classroom, with movable furniture, plus Wednesday Addams and Thornhill minidolls. Closed, it stands a little over 9 inches tall, so it can stay on a shelf as gothic room decor once the build is done. It is rated for ages 9 and up, which makes it a fit for a preteen fan of the show at Halloween or on a birthday.

Best for : A preteen or teen who follows the Wednesday series and likes to build
Best occasion : Halloween, a birthday
Why it works : It gives a fan two things in one box, a build with a hidden reveal and a dark flower piece that can stay on display in their room afterwards.
