New LEGO Botanical Collection Sets for March 2026 Leak Online

Two more LEGO Botanical Collection sets are reportedly coming in March 2026, according to some newly surfaced information from a reliable source. The leak identifies the upcoming LEGO sets by name, in addition to outlining their alleged price tags and piece counts, among other details.

The information comes from Instagram user lego_minecraft_goat, who has built a substantial and consistently reliable track record of credible LEGO scoops. In the past 12 months alone, they have leaked sets including 11372 Autumn Cottage Garden, 75413 Republic Juggernaut, and 75414 The Force Burner Snowspeeder, among plenty of others.

Two New LEGO Botanical Collection Sets Reportedly Coming in March 2026

The insider's latest report saw them outline two unannounced sets said to be part of the Botanical Collection, which is currently among the most popular LEGO themes for adults. The upcoming sets are said to be 11502 Sunflower Bouquet and 11510 Magnolia Branches. The former will reportedly consist of 686 pieces and retail for $59.99, while the latter is expected to have 435 pieces and a $49.99 price tag. Both are rumored for a March 2026 release. Historically, new Botanical Collection sets have launched at the beginning of their release month, making March 1 the most likely release date if this report is accurate.

LEGO Botanical Collection 2026 Sets

The rumored Sunflower Bouquet set will likely incorporate elements from 40524 Sunflowers, a small display-oriented kit released by LEGO in January 2022. In contrast, Magnolia Branches may introduce entirely new parts or building techniques, as magnolias have yet to be featured in any official LEGO set. If both kits are indeed part of the March 2026 lineup, an announcement could arrive in the coming weeks, potentially before the end of January. The exact timing may depend on whether LEGO plans to offer pre-orders; if so, the new sets will likely be revealed no later than late January.

LEGO Group

The Botanical Collection received four new sets on January 1, thus becoming one of the first LEGO themes that were expanded in 2026. The new additions include 11501 Tulip Bouquet, 11504 Peace Lily, 11508 Daisies, and 11509 Flowering Cactus. The Tulip Bouquet is the largest and most expensive kit from this batch, numbering 576 pieces and retailing for $59.99. Two additional Botanical Collection sets have previously been confirmed for a February 1 release: 11503 Flower Wall and 40957 Spring Wreath, priced at $89.99 and $39.99, respectively.

In addition to Magnolia Branches and Sunflower Bouquet, the March 2026 Botanical Collection expansion is also rumored to include a "Floral Picture Frame" kit. Identified by set number 40916, it is said to be a Gift-with-Purchase product that won't be sold individually and will instead only be included with qualifying purchases while supplies last. Given that, the Floral Picture Frame is likely to be relatively small, with a piece count unlikely to exceed 300. Separately, LEGO is also rumored to be preparing a follow-up to its 2025 set 10349 Happy Plants, which featured two smiling flower pots. The sequel, Happy Plants 2, is expected to include 253 pieces—36 more than its predecessor—and release on May 1, 2026, according to previous leaks.
