Eva Solo's Simply Grow spire planter is designed to help your summer flowers and herbs thrive all season long – its angled, hinged glass lid creates optimal conditions for germinating seeds and delicate seedlings, while also protecting them from chilly spring nights and heavy rain. Standing on slim legs, the planter box features a clever self-watering system that uses a capillary mat at the base to deliver just the right amount of water to your plants. If the built-in water reservoir fills up due to heavy rain or overwatering, the excess water drains out – something to keep in mind when using the planter indoors. For best results, place your plants in their own pots inside the box. This ensures the self-watering system works as intended and makes it easier to rearrange or switch out plants. You can also pair the spire planter box with a matching plant support, sold separately.

The Simply Grow collection features modern, low-maintenance garden essentials designed especially for outdoor use. Made from weather-resistant galvanised steel, the planters and pots are built to withstand the elements year-round – even in harsh northern climates. Powder-coated in sleek black, the collection's elegant, streamlined forms and matching plant supports suit everything from urban balcony gardens to larger patios and yards.
