Every plant is carefully packed by our small, plant-loving Bristol team using protective, mostly plastic-free packaging.

Occasionally, you may find reused bubble wrap – this has been donated to us, and we encourage you to reuse it too.

Orders are usually packed and dispatched within 2–4 working days. We may occasionally delay dispatch during periods of extreme weather to protect your plants. We always prioritise plant health over speed of delivery.


Delivery is £4.99 for any number of items, or free on orders over £60. We deliver across the UK only.

We also offer local, bike-powered delivery in Bristol for £4.99 via Pedal Collective, a gentler option for plants and the planet.

We believe in paying people fairly, that’s why we’ve been a Real Living Wage Employer from the very beginning. We’re an independent Bristol business, packing every order ourselves.

Supporting us means supporting fair work.

Clay Pebbles, Clay Balls or Lightweight Expanded Clay Aggregate - The only thing you need for your semi hydro set up (except water of course). The small balls of clay wick up water upwards, meaning a little pool of water at the bottom of a pot made for semi hydro can hydrate all the way to the top! The balls also provide massive chambers of oxygen for roots to grow super strong which you will see the rewards of in your foliage. Conversely, you can add clay balls into soil for extra water retention in your mixture.
