Huge, puckered leaves with a sweet, rounded basil scent
Key benefits
'Bolloso Napoletano' is the big-leaved basil of Naples, with leaves so large and puckered that a single one covers a slice of pizza. This heirloom Ocimum basilicum grows bright green, blistered, lettuce-like leaves with a sweet, rounded basil scent and none of the harshness some varieties develop in heat. Tear them over margherita and caprese, blend them into pesto, or use whole leaves to wrap mozzarella. It makes a lush, upright plant for a sunny windowsill, greenhouse or warm patio pot, and the more you pick, the bushier it grows.

Your quick reference for choosing the right plant size. We group our plants by the diameter of their nursery pots which gives you a consistent way to understand scale.
Small but full of charm. These compact plants are perfect for desks, windowsills, and small shelves, or for building out a collection over time. Ideal if you enjoy watching your plants grow from the beginning. Approx. height: 10–20cm
A step up in presence, great for side tables, shelves, or styling in clusters. Easy to move around and perfect for adding greenery without taking up too much space. Approx. height: 25–35cm
Our most versatile size. Works beautifully on shelves, desks, and plant stands, offering a fuller look without dominating a space. A great balance between impact and flexibility. Approx. height: 25–50cm
More established plants with fuller foliage and stronger structure. Ideal for creating soft focal points in a room. Great for corners, beside furniture, or as standalone features. Approx. height: 40–70cm
Big, impactful plants designed for floors and open spaces. These are your statement pieces and are perfect for anchoring a room or transforming a corner with instant greenery. Approx. height: 60cm–1.3m
Sow indoors from March to May in a warm spot around 20°C. Basil hates cold, so keep it inside or under glass until June, when nights are reliably mild. A few sowings a month apart keep fresh leaves coming all summer.
Yes. A 20 cm pot on a sunny windowsill or patio suits one plant well. Water at the base in the morning rather than over the leaves, and pinch out the growing tips to keep it bushy.
Both are sweet basils, but 'Bolloso Napoletano' has much larger, crinkled, paler green leaves with a softer, sweeter scent. Genovese has smaller, flatter, darker leaves and a sharper flavour that is classic for pesto.

Choose your delivery speed at checkout. Express orders placed before 1pm are dispatched the same day, otherwise the next working day. Standard orders are dispatched within 2 to 3 working days and Economy orders within 4 to 5 working days. Once dispatched, every order travels by 24 hour tracked courier.
Delivery is free on orders over £60 with Economy, over £100 with Standard and over £150 with Express. Below that, the charge depends on your basket total and is always shown at checkout before you pay. The full price list is in our shipping policy.
Orders without plants are dispatched Monday to Friday. If your order also includes plants, it goes out Monday to Thursday so the plants are not left in the courier network over the weekend. Delivery can take longer at busy times such as Black Friday and Christmas.
