Larkspur – Rocket Carmine

Rocket Larkspur is a striking annual flower native to southern Europe and the Mediterranean region. The Carmine variety produces tall, graceful spires covered in vivid rose-red to deep pink blossoms that bring rich, eye-catching color to garden borders, cutting gardens, and wildflower plantings. Its bright, saturated hues stand out beautifully against the plant’s soft, fern-like foliage, creating a dynamic contrast that adds both height and texture to the landscape. Mature plants typically reach between two and four feet tall, with multiple stems rising from the base for a full, elegant display.

Carmine Rocket Larkspur is a favorite among gardeners and floral designers for its long, upright stems and excellent performance as a cut flower. The blooms hold their vibrant color beautifully in both fresh and dried arrangements, making them a staple in cottage-style and traditional garden designs.

All parts of the plant — including the leaves and seeds — are poisonous if ingested. They contain natural alkaloids that can be harmful to humans and animals, so take care when planting around children or pets.

For best results, Rocket Larkspur can be planted in either fall or early spring. In regions with mild winters, fall planting often produces stronger, earlier-blooming plants. If sowing in spring, refrigerate the seeds for one to two weeks before planting to simulate winter conditions and improve germination. The seeds sprout best in cool soil and may not germinate well once the ground warms.

Plant in full sun to partial shade in well-drained soil with moderate moisture. Rocket Larkspur prefers cooler growing conditions and does not tolerate soggy soil or excessive summer heat. Blooming typically begins in late spring and continues through summer, with successive sowings extending color into early fall. Because this plant develops a long taproot, it is best sown directly into the garden rather than transplanted once seedlings appear.

With its tall, vibrant carmine-red flower spikes and soft, airy foliage, Rocket Larkspur brings brilliant color, vertical structure, and classic charm to any garden — a timeless favorite for borders, wildflower meadows, and cut-flower arrangements.
