Tummelberry (Rubus fruticosus × R. idaeus) is a vigorous hybrid between raspberry and blackberry, developed in 1984 by the Scottish Crop Research Institute (SCRI). This bramble produces large, round, bright-red berries that resemble raspberries in appearance but carry a juicy, sweet-tart flavor with blackberry-like depth. Tummelberries ripen from mid-July through late August, offering an extended summer harvest that’s ideal for fresh eating, preserves, desserts, or freezing.

Perfect for home gardeners seeking high flavor and low fuss, Tummelberry plants thrive when grown in full sun, with well-draining, fertile soil and regular watering. Though slow to start from seed, they establish quickly from cane cuttings or bare-root canes. Train them along a trellis or fence and prune annually to encourage airflow and maximize yields. Hardy and productive, Tummelberry is a standout choice for berry lovers who want reliable harvests, bold color, and a flavorful twist on the traditional raspberry.

How to Plant Tummelberry from Seed

When to Plant Seeds

Germination can take 4 to 12 months, and may be erratic.

Maintain consistent moisture, warmth, and light during this period.

Covering with a humidity dome or plastic wrap can help retain moisture.

Preparing Seeds for Planting

After stratification, press seeds on the surface of a light, well-draining seed-starting mix (e.g., peat and sand or coconut coir).

Do not bury the seeds deeply—just gently press them into the surface.

Keep the soil lightly moist and place the container in bright, indirect light at 18–22°C (65–72°F).

Transplant

Once seedlings emerge and have developed 2–3 true leaves, transplant into small pots.

Provide bright light, water when the top inch of soil is dry, and begin feeding with diluted fertilizer.

Harden off before transplanting outdoors in spring, spacing plants 1.5–2 m (5–6 ft) apart with support ready for cane growth.

Harvesting

Fruit ripens mid‑summer to early fall; ready when deep purple to black, juicy, and slightly soft.

Harvest every 1–2 days during peak production—they do not store well and can leak juice quickly

Pro Tip

Train and prune efficiently: After harvesting, remove old floricanes promptly. In early spring, retain just 5–7 vigorous primocanes per plant, trimming lateral growth for airflow. Train fruiting canes horizontally on a two-wire trellis and tip-layer new canes to contain spread—or prune tips to manage rooting. This structure optimizes yield, simplifies picking, and minimizes unwanted spread through self‑layering

Getting to know your Tummelberry

The Tummelberry is not here to be subtle. With its deep red-purple fruit, sprawling vines, and in-your-face flavor, this bramble hybrid is like the rebellious middle child of the berry world—equal parts blackberry and raspberry with a loud, juicy attitude.

Hardy and high-yielding, Tummelberries handle cooler climates better than many other berry hybrids, making them an excellent choice for northern growers. They're not delicate, they're not picky, and once established, they come back swinging year after year.

In essence, the Tummelberry is a berry with a point to prove. Not content to be just another raspberry or blackberry, it’s here to steal the show—and your heart.

Our Seed Safety Promise

We do not sell genetically modified seeds — ever. And we don’t use genetic engineering to breed new varieties. Instead, our skilled breeders use traditional, natural crossing methods to create hybrid seeds that are healthy, safe, and packed with potential.

Our Seed Quality Guarantee

At Shido, we believe great gardens start with great seeds — and that means quality comes first. Every seed lot we offer is ensure to generate top-notch germination because your garden deserves nothing less.

To keep our seeds at their peak, we run thorough pathology tests at trusted outside labs. When you open a Shido seed packet, you can trust it’s been nurtured, tested, and approved to give you strong, healthy plants from the very first sprout.

Types of Seeds We Offer

Hybrid Seeds (F1)

F1 hybrid seeds are the garden’s high achievers — created by crossing two specially chosen parent plants for superior vigor, uniformity, and performance. We use only traditional breeding methods to produce these powerhouse seeds.

Open-Pollinated & Heirloom Seeds

Our open-pollinated (OP) seeds naturally reproduce through wind, insects, water, or self-pollination. When grown in isolation, they produce true-to-type plants year after year.

Among our OP seeds are treasured heirloom varieties — old favorites that have been carefully passed down for generations. While OP plants can be less uniform than hybrids, we run our Open-Pollinated Project to select the most reliable, flavorful, and beautiful strains. Many are also available as certified organic seeds.

Non-GMO: What It Means and Why It Matters

A GMO (Genetically Modified Organism) is created when scientists alter a plant’s DNA in a lab — often by inserting genes from completely unrelated species — to achieve certain traits, like pest resistance or herbicide tolerance. This is a far cry from natural plant breeding.

At Shido, we believe gardening should stay as close to nature as possible. All our seeds — whether hybrid, heirloom, organic, or open-pollinated — are Non-GMO. They’re bred using traditional methods that respect natural biodiversity, giving you safe, wholesome seeds that grow into plants just as nature intended.

When you plant Shido Non-GMO seeds, you’re choosing purity, sustainability, and peace of mind — along with a garden full of flavor, color, and beauty.

Vacuum-Sealed for Freshness — Good for 10 Years

Every Shido seed packet is vacuum-sealed to lock in freshness and protect your seeds from moisture, air, and pests. This careful packaging not only preserves their quality but also extends their shelf life dramatically. Stored properly in a cool, dry place, our seeds remain viable for up to 10 years — so you can plant them now, next season, or even years down the road. Whether you’re planning a garden this spring or building a long-term seed stash, Shido seeds are ready when you are.
