Alder Cones

Alder cones are small, woody seed cones collected from the Alnus rubra tree in the USA. Valued for both their natural look and functional benefits, they’re a popular choice for aquariums, terrariums, and creative projects.

Uses

• Aquariums & Paludariums: When prepared, alder cones release a higher level of tannins, support beneficial biofilm growth, and help create a more natural environment for fish and shrimp.

• Bioactive Terrariums: Provides shelter and grazing material for isopods and springtails while slowly enriching the substrate as they break down.

• Decor & Crafts: Great for botanical décor, terrariums, potpourri, wreaths, fairy gardens, and mixed-media art.
