What's Included

The 358-piece set delivers impressive content for its budget price point. Two exclusive minidolls lead the package: Wednesday Addams featuring exceptional facial printing that captures Jenna Ortega's likeness with uncanny accuracy, and Professor Marilyn Thornhill in her botanical teaching attire. The black dahlia flower construction includes stem, leaves with light purple buds, and the signature dark bloom that gives the set its name. The vase transforms into a mini conservatory classroom complete with removable desks, stool, blackboard elements, and botanical accessories. Instructions guide through a straightforward 45-minute build process, though sticker sheets for leaf detailing require patience for optimal results.
Building Experience
Construction unfolds efficiently over approximately 45 minutes, beginning with the vase base that conceals the classroom interior. The build process proves surprisingly engaging for a budget set, utilizing clever techniques to achieve the transformation mechanism. The vase assembly employs SNOT construction for smooth exterior surfaces while maintaining the internal cavity for the hidden room. Flower construction follows, with the stem utilizing Technic elements for stability and positioning. Each petal of the dahlia attaches individually, creating satisfying repetition that builds toward the complete bloom. Sticker application for the leaves proves the only frustration, requiring careful alignment for symmetrical appearance. The experience exceeds expectations for sub-£20 sets, delivering techniques typically reserved for premium offerings.
Design and Accuracy

The black dahlia captures the gothic aesthetic perfectly, though the predominantly black coloration limits visual impact compared to traditional dahlia hues. Standing 24cm tall when displayed in the vase, the proportions feel accurate to both real flowers and the show's oversized botanical specimens. The flower head utilizes layered building techniques creating realistic depth and texture, while purple accents on the buds add subtle color variation. The vase design cleverly disguises its dual nature, appearing as an ornate Victorian-style container that fits Nevermore Academy's aesthetic. When opened, the classroom reveals surprising detail—tiny desks, botanical charts, and teaching accessories that capture the academic setting despite space constraints.
Play Features
The transformation mechanism operates smoothly—removing the dahlia flower unlocks the vase, which opens to reveal the hidden classroom interior. This simple but effective feature creates genuine surprise during first discovery. The classroom includes removable furniture allowing scene customization, though the cramped space limits elaborate setups. Minidolls interact naturally with classroom elements, recreating botanical lessons or Wednesday's investigations. The flower itself offers minimal play value beyond display, though its modular construction allows color customization for builders with spare parts. Integration with other Wednesday sets remains limited given this is only the second release, though the minidolls enhance any Nevermore Academy display.
Display Worthiness
As a display piece, the black dahlia exceeds expectations dramatically for its price point. The gothic flower creates an striking centerpiece that wouldn't look out of place among LEGO's premium Botanical Collection, despite costing significantly less. The 24cm height provides presence without overwhelming shelf space, while the dark coloration ensures it complements various decor styles beyond just Wednesday themes. Displayed with the vase closed, it functions as pure decoration; opened to reveal the classroom, it becomes a conversation piece showcasing LEGO's clever design. The minidolls display excellently beside the vase, with Wednesday's exceptional likeness drawing attention. Multiple display configurations—flower in vase, flower separate with classroom exposed, or components arranged as a scene—provide versatility rare in budget sets.
Value Analysis & Investment
At £19.99 for 358 pieces, the 5.6p per piece ratio represents exceptional value in today's market, particularly for a licensed set with exclusive characters. Current European pricing shows even better deals with Amazon Germany offering €17.29, making this an absolute steal. The minidolls alone justify the purchase—Wednesday's perfect likeness will command premium aftermarket prices, while Professor Thornhill remains exclusive to this set. Comparison to LEGO's Botanical Collection highlights the value: similar-sized flowers retail for £15-25 without minifigures or play features. Investment potential appears strong given the Netflix series' popularity and the set's limited availability window. The combination of display appeal, character exclusivity, and reasonable pricing suggests steady appreciation. Smart buyers should purchase at retail or modest discounts, as this represents rare genuine value in modern LEGO pricing.
