We broke a curious LEGO mobile-app slip-up today: per Game Rant, a crystal-clear product image of an unannounced Botanicals set identified as 11513 Dark Flowers appeared in a premature app update. The preview image reportedly included a tagline encouraging builders to combine the model with 11514 Cosmos Flowers, which has already been unveiled and carries a clear release plan.
What was reported
Per Game Rant, the leak came not from an internet sleuth or supply-chain tipster but from a mistaken internal publish inside LEGO’s mobile app — a premature app update that exposed a product image without the usual context. The leaked photo allegedly shows 11513 Dark Flowers and 11514 Cosmos Flowers combined into a single, larger floral display, with a tagline prompting builders to pair the two sets.
Details in the preview include confirmed information about 11514 Cosmos Flowers: Game Rant reports it is a 171-piece model with a 9+ age rating, and that it was formally unveiled earlier in May 2026 with an announced June 1 release date. The leaked image suggests 11513 Dark Flowers has a piece count "in the ballpark of 600" and is therefore likely to debut with an 18+ rating, reflecting what appears to be a more intricate build.
Visually, the leaked build was described as having a gothic-botanical aesthetic. The arrangement reportedly uses black, deep red, plum, dark purple, forest green, and magenta paired with glossy black vase-like forms, saturated blooms, pale accent flowers, and dense foliage. Game Rant lists possible real-life inspirations visible in the combined arrangement as roses, dahlias, pansies, anemones, calla lilies, lavender, and hydrangeas, while noting cosmos, daisies, and hyacinth-like elements are likely tied to the officially announced 11514 Cosmos Flowers.
The source and credibility
We’re basing this on a single reported internal gaffe — per Game Rant, an internal LEGO department accidentally published the image via the LEGO mobile app. The image was reportedly "crystal-clear" but was shared without broader product copy or context, which is why some details (like the exact piece count and official age rating for 11513 Dark Flowers) remain inferred rather than confirmed.
Take this with a pinch of salt: Game Rant frames some conclusions as plausible or likely rather than confirmed. For example, the idea that 11513 Dark Flowers will carry an 18+ rating is drawn from the apparent piece count and complexity visible in the image rather than an explicit catalog listing. Game Rant also notes that other Botanicals sets — 11505 Woodland Mushrooms (18+, 806 pcs.) and 11511 Water Lilies (9+, 259 pcs.) — are still awaiting their June 2026 debuts, which adds context but not confirmation to any timing guesses.
There’s additional context in the report that LEGO has reportedly faced internal production challenges recently; Game Rant cautions these issues may be affecting flagship releases and could influence release timing for other sets, though it’s unclear how deeply that impacts the Botanicals lineup.
What it could mean
If true, this leak indicates LEGO is continuing to treat the Botanicals collection as a core adult-focused line, with a willingness to produce both compact 9+ models like 11514 Cosmos Flowers and substantially larger, more intricate builds such as the allegedly 600-piece 11513 Dark Flowers. The compatibility hinted at by the app copy suggests LEGO may push interlocking or combinable display pieces across multiple Botanicals releases.
It also signals a stylistic direction: a "gothic-botanical" palette — darker hues and ornate forms — which might broaden the display appeal of the Botanicals family for collectors seeking a more mature-looking floral arrangement. That could make the line feel less like casual desk decor and more like collectible decorator pieces.
That said, much remains unverified. The premature app update is a single point of evidence; official listings, product pages, or retailer information would be needed to confirm exact piece counts, ratings, pricing, or availability. Game Rant’s reporting flags these elements as probable rather than definitive.
Why This Matters
For builders and collectors who follow the Botanicals range, an allegedly leaked 11513 Dark Flowers that pairs with 11514 Cosmos Flowers would be notable for a few reasons. First, it reinforces that LEGO is exploring modularity and cross-set compatibility within a non-licensed lifestyle line — a strategy that encourages multiple purchases to create larger displays. Second, a likely 18+ rating and higher piece count point to continued adult targeting, which has been central to Botanicals since its early 2021 debut.
Finally, if LEGO is indeed grappling with production challenges as reported, availability and timing could be unpredictable — meaning leaks like this, accidental as they are, become one of the earlier indicators collectors might use to prepare. As always, we’ll be watching for an official confirmation from LEGO Group and will update you if and when more concrete listings or product pages appear. For now, take the leak with a pinch of salt, but enjoy the early look at what could be one of the more striking entries in the Botanicals line.
