The Sill

What's in the box: Each month brings one plant hand picked by The Sill's team, with the exact plant left as a surprise.

The Sill is a US plant retailer that sells indoor and outdoor plants, planters, and care accessories, and it also runs a monthly plant subscription. According to its website, subscribers choose a three, six, or twelve month plan, and The Sill's team hand picks a new plant to send each month, starting from $69 per month. The homepage does not say exactly which plants or pot sizes subscribers should expect, so the surprise element cuts both ways. It is fun if you enjoy variety, but less ideal if you have tricky light conditions or pets and want to vet every plant first. The wider shop suggests a deep pool to pick from, with hundreds of indoor and outdoor plants listed, including dedicated pet friendly and easy care categories. The Sill advertises a plant guarantee and unlimited plant care support, which is a real benefit for beginners who are likely to have questions. Gift orders arrive without pricing in the box and can include a note at checkout, so the subscription works well as a present. The main drawback is cost. At the starting monthly price, a full year adds up quickly compared with buying individual plants you choose yourself. Shoppers who want control over each pick may prefer the regular catalog.
