Sunflower ‘Big Smile’ (Helianthus annuus)

Sunflower ‘Big Smile’ (Helianthus annuus) is a cheerful dwarf sunflower variety known for its bright yellow petals and dark centres on compact plants. This variety is specially bred for small spaces, producing large, classic sunflower blooms on short, sturdy stems.

Big Smile sunflowers are ideal for containers, patio planters, borders, and children’s gardens due to their manageable size and fast growth. Despite their compact habit, they deliver bold visual impact with oversized blooms relative to plant height.

Well-suited to Alberta’s summer conditions, this variety thrives in full sun and warm temperatures. It is grown as an annual in Lethbridge and provides reliable mid to late summer colour.
