Cynoglossum Officinale
Cynoglossum officinale Seeds
A structural native beauty with clusters of deep, dull maroon-red flowers. Its velvety grey-green leaves and gothic charm make it a dramatic choice for dry banks and wild borders.
While most wildflowers are bright and breezy, Houndstongue brings a touch of dramatic, gothic beauty to the wild garden. This native biennial produces tall, sturdy stems topped with clusters of small, funnel-shaped flowers in a unique shade of deep, dull maroon-red (sometimes fading to violet).
The name comes from the texture of its leavesβlong, broad, and covered in soft, greyish hairs that feel rough yet velvety, just like a dog's tongue. It is a structural, architectural plant perfect for dry banks, coastal gardens, or wild borders where you want something darker and more interesting than the standard daisy shapes.

πΏ Understanding the Plant
Cynoglossum officinale is a robust Hardy Biennial (H7). As a native wildflower, it is perfectly adapted to the UK climate, surviving the coldest winters with ease. It follows a two-year cycle: forming a velvety grey-green rosette in its first year and sending up its structural flower spikes the following summer.
Nature's Velcro: A distinctive feature of Houndstongue is its seed production. After flowering, it develops four-part nutlets covered in tiny hooked prickles (burrs). Designed by nature to hitch a ride on passing animals, these "sticky" seeds are a fascinating example of botanical dispersal, though they are best planted at the back of borders away from long-haired pets!
RHS Plants for Pollinators: This species is officially recognized for its high nectar value. It is a vital food source for bumblebees and other long-tongued insects during the early summer months, making it a critical addition to any biodiversity-focused wild garden.
π± Growing Guide
Houndstongue is a tough, low-maintenance native that thrives on neglect once established.
How to Sow:
Sow directly outdoors in Autumn (September-October) or Spring (March-May). Scatter the large seeds onto bare, raked soil and cover lightly (approx. 5-10mm deep). Autumn sowing is often more successful as the natural winter cold helps to break seed dormancy, leading to stronger spring germination.
Where to Plant:
They demand full sun or partial shade and thrive in dry, sandy, or chalky soils. Houndstongue is an ideal choice for coastal gardens or well-drained banks. It deeply dislikes heavy, waterlogged clay; if your soil is damp, consider growing in a raised area or adding plenty of grit to the planting site.
Ongoing Care:
Once established, this plant is exceptionally drought-tolerant and requires almost no intervention. If you wish to prevent the plant from self-seeding and spreading via its "sticky" seeds, simply cut the flower stems down to the base immediately after the flowers fade in July.
π Plant Specifications

| Common Name | Houndstongue / Gypsy Flower |
| Plant Type | Hardy Biennial Wildflower |
| Hardiness | H7 (Ultra Hardy Native) |
| Light Requirements | Full Sun / Part Shade β |
| Height | 60cm - 80cm |
| Spread | 45cm |
| Spacing | Plant 40cm apart |
| Flowering Period | May to July (Year 2) |
| Perfect For | π Gothic & Moody Borders πΎ Naturalistic Wildflower Meadows ποΈ Dry, Coastal or Sandy Soils π High-Quality Bumblebee Forage |
| Seeds per Packet | Approximately 35 large seeds |
π€ Beautiful Wild Combinations
Houndstongue looks its best in a naturalistic or wild setting. Pair it with these available species from our collection:
- ποΈ White Campion: The Contrast. The pure white flowers of the Campion provide a luminous backdrop that makes the sombre, dull maroon of the Houndstongue truly stand out. Both species thrive in similar dry, hedgerow-style conditions.
- π Viper's Bugloss: The Coastal Duo. If you have sandy or dry soil, grow these two together. The electric blue spikes of the Echium and the deep maroon-red of the Cynoglossum create a high-impact, bee-friendly display that looks spectacular on coastal banks.
π Sowing & Flowering Calendar
Direct sow in autumn for the strongest plants, followed by dramatic maroon spikes the following early summer.
β οΈ Pet Warning
The seed burrs of Houndstongue are incredibly "hooked" (functioning like nature's Velcro). If you have long-haired pets, we recommend planting this at the back of a border where they won't brush past it, or cutting the flower stems before the seeds fully ripen.
π Native Gothic Beauty
Known for its stamina and ability to thrive on dry, sandy soils, Cynoglossum officinale is an essential choice for those wanting to create a moody, structural wild garden that supports essential early-summer pollinators.
