Mixed Ornamental Sunflower - Organic
$4.49
Unit price perNative to the Great Plains of North America, the sunflower ( Helianthus annuus ) has long been a staple food for people and a companion plant in the fields. In its ornamental mixed variety, the sunflower comes in a mosaic of heights, shapes, and colors ranging from bright yellow to coppery tones, sometimes brick red or soft lemon.
Sown in fertile soil, this mix creates a veritable living tableau throughout the summer. The taller plants stand guard over the vegetable garden, while the more compact varieties weave their way into flowerbeds or along the edge of a quiet corner. The abundant centers of their flower heads attract bees, bumblebees, and other winged visitors, contributing to a harmonious garden rich in biodiversity.
Easy to grow where the season is warm enough, this mixed ornamental sunflower is a reliable plant: an age-old practice of sowing in spring, some careful care at the start, and the reward of a generous flowering that accompanies the cycle of seasons until the first frosts.
