Houseplant Size Guide
At Houseplant.co.uk, we want to ensure that you choose the perfect plant for your space. Here's how we measure our plants:
Plant Height:
Measured from the base of the nursery pot to the top of the plant, including the full length of the stem and foliage.
Pot Size:
Refers to the total width across the top of the pot.
Choosing the Right Size
To find the perfect fit, compare the diameter of your plant's grow pot to the opening diameter of your chosen decorative pot. Ensure the decorative pot is at least 1-3cm larger in diameter than the grow pot for easy insertion and removal.
Important Notes
- Plant sizes are approximate and include the depth of the plant pot and roots, not just the height from the top of the soil.
- If a specific plant size is not available, we may provide a larger plant at no additional cost to you.

RARE PLANT
You're lucky you found me!
Marimo, meaning in Japanese - 'Seaweed Ball' - are a curious spherical algae that is considered lucky. Marimo is a rare growth form of Aegagropila Linnaei, a fancy name for a special kind of Algae. It can be found in lakes and rivers in Japan and Northern Europe where the climate permits its natural growth, though populations are on the decline. Instagram worthy, Marimo Balls are fuzzy little cuties & perfect for a low maintenance plant pet! Terrarium design may vary.

Marimo | Moss Ball | Rare Plant ordered with other itemsThe plants came well packaged and
The plants came well packaged and protected in eco friendly packaging which was great. Was a little disappointed with the odd shape of one of the moss balls but hopefully I can trim it to make it more spherical
