Description

Lobelia erinus 'Emperor William' forms fairly large, bushy mounds of light green foliage (30 cm tall, minimum 30 cm spread). It flowers profusely from June until September, displaying masses of small, indigo, butterfly-like blooms. Perfect for filling out hanging baskets and containers!

Lobelia erinus, also known as edging lobelia, is a popular plant for containers and hanging baskets. It produces numerous slender, branched stems which come together to form soft, rounded cushions. Leaves are small and narrow, light green to dark green in colour; all summer long, they are smothered in abundant blooms. Each flower measures about 1 cm long, with a tubular base, flaring out into three large downward-facing petals and two smaller upward-facing petals. They are regularly visited by foraging insects.

Lobelia is a great edging plant for sunny borders and summer bedding schemes. It shines in containers and hanging baskets, effortlessly blending in and highlighting other summer-flowering annuals. It enjoys a sunny position, preferably shaded from scorching afternoon heat, in moist, well-drained soil. It suffers from drought, so make sure to water regularly. For extra vigour, feed with fertilizer once every so often. In the right growing conditions, Lobelia will flower continuously from early summer until October.

Lobelia seeds are best left to experienced, seasoned gardeners as they are extremely small, like fine dust.
