The LEGO Botanicals Flower Arrangement (Set 10345) is a 1,161-piece building set designed for adults ages 18 and up, featuring an elegant collection of 14 buildable flowers displayed in a brick-built white pedestal vase. The set includes seven distinct flower varieties: camellias with Star Wars spaceship parts as outer petals, peonies with umbrella and seashell elements, labor-intensive hydrangeas featuring 68 butterfly subassemblies, delicate baby's breath with new three-pronged stalk pieces, Persian buttercups built with SNOT techniques, bouvardia showcasing ladybird wing cases in medium lavender, and lilies with newly-designed botanical-specific leaf and petal pieces.

The completed arrangement measures over 12.5 inches wide, 10 inches high, and 9 inches deep, making it an impressive display piece for home or office. The set employs advanced building techniques including stud inversion using half cylinders and clip-and-inkwell combinations, SNOT construction for the vase core, and angled branching with Brick Round 1x1 with 3 Bars pieces. The innovative pin system allows flower heads to be removed and swapped with flower heads from other LEGO Botanicals sets, enabling builders to create fully customizable arrangements.

The included white pedestal vase features 24 vertical bars for secure stem attachment, eliminating the need for external containers and providing plenty of connection points for flexible flower placement. The set introduces 14 new color variations across existing molds, including reddish orange, orange, bright light yellow, lime, multiple shades of green, purple, lavender, dark red, and magenta elements. Both printed and digital building instructions are included for an immersive building experience.
