Sainfoin Meadow Blend Wildflower Seeds

Onobrychis viciifolia

Other names: mountain sainfoin, esparcet, holy clover 

Literally crack for bees. Sainfoin nectar can have a sugar concentration of up to 60%, and the plants can yield up to 350 pounds of honey per acre.

This hardy perennial requires no maintenance and can be planted on the poorest quality soil. In fact, the magic of sainfoin is that it will improve the soil quality for other plants. Scatter these seeds for a glamorous show of rich-pink flowers for years to come.

How to Plant

Cheap and Easy Method:

For a straightforward and cost-effective approach, scatter the Sainfoin seeds directly onto bare soil. This method requires minimal preparation but has a lower success rate as it relies heavily on natural conditions being favourable. Clear the area of any debris and lightly rake the soil to create a loose surface. Evenly broadcast the seeds across the soil, then lightly rake again to ensure good seed-to-soil contact.

More Involved Method:

For better results, particularly in areas with aggressive weeds or where the soil may be particularly challenging, consider using a terram membrane. This method involves laying a terram membrane over the planting area to suppress unwanted vegetation. Over this membrane, add a layer of soil that is suitable for Sainfoin growth. Sow the seeds evenly across the soil surface and gently press them in to ensure good contact. This method, while more expensive and labour-intensive, significantly increases the likelihood of establishing a vibrant and sustainable stand of Sainfoin.

Alternative Methods:

1. Seed Trays and Transplanting: Start the seeds in seed trays or small pots indoors. Once the seedlings are large enough to handle, transplant them to their final growing location. This method allows for better control of the early growth stages and protection from adverse conditions.
2. Direct Sowing with Mulch: Scatter the seeds directly onto prepared soil and cover lightly with a thin layer of mulch. The mulch helps retain moisture and suppress weeds, giving the seeds a better chance to germinate and establish.

When to Plant

The optimal time to plant your Sainfoin seeds is in the spring (March to May) or early autumn (September to early October). These periods offer the best temperatures and adequate moisture levels for seed germination and root establishment.

Where to Plant

Sainfoin thrives in well-drained, calcareous soils with a high pH. It is ideal for planting in areas with full sunlight. Choose a location that receives at least six hours of direct sunlight per day. Avoid areas prone to waterlogging, as this can hinder seed germination and plant growth.

Watering Schedule

During the initial establishment phase, maintain a consistent moisture level in the soil, keeping it moist but not waterlogged. Water the seeds gently to avoid washing them away. Once the plants are established, they typically require minimal watering, relying on natural rainfall. However, during prolonged dry spells, occasional watering may be necessary to maintain healthy growth.

Blooming Period

Sainfoin generally blooms from late spring to early summer, approximately from May to July. The exact timing can vary based on regional climate specifics and yearly weather variations.

Expected Plant Height

Sainfoin typically grows to a height of 60 cm to 90 cm. This variation creates a textured, dynamic appearance that provides depth and interest, while also supporting a diverse range of wildlife and pollinators.

Summary of Planting Methods

Cheap and Simple Method:

• Scatter seeds directly onto bare soil or in pots/growing boxes.
• Lightly rake the soil before and after scattering seeds.
• Suitable for small and large areas.

More Involved Method:

• Use a terram membrane to suppress weeds.
• Add a suitable soil layer over the membrane.
• Sow seeds and press them in gently.
• More labour-intensive but higher success rate.

Alternative Methods:

1. Seed Trays and Transplanting: Start seeds indoors and transplant seedlings.
2. Direct Sowing with Mulch: Scatter seeds and cover lightly with mulch.
