3 Large Plants - Lobelia Springs Lavender, Ready to Plant in Your Garden

A compact, free-flowering summer bedding plant that delivers clouds of colour from late spring through autumn.

Upright lobelia produces masses of small, five-lobed flowers held closely together to form dense, dome-shaped displays above fine, bright green foliage. Available in rich blues, soft lavender, crisp white, and gentle pastel tones, these varieties offer strong visual impact despite their delicate flower size. Naturally bushy and floriferous, they’re ideal for containers, hanging baskets, window boxes, and the front of borders, where they add texture, colour, and lightness to planting schemes.

Supplied as large, well-established 10.5 cm rootballs, these plants are ready to plant straight outdoors and establish quickly. Grown in peat-free compost, they’re easy to care for and reliably flower throughout the warmer months. Suitable for gardeners of all experience levels, upright lobelia performs best with regular watering and occasional feeding, rewarding minimal effort with consistent, long-lasting colour.
