Phacelia Tanacetifolia Seeds

Phacelia is a very quick growing annual green manure that can be sown successfully from march till September. The plants grow up to 1m in height and is tolerant of cold temperatures so should survive the winter if it's not too severe.

Phacelia is particularly good at smothering weeds and have an extensive root system which improves soil structure. It will self seed to easily so if using it as a green manure it's a good idea to dig in before it flowers. If you are covering a spare patch of ground for a longer length of time let it flower, they are beautiful. Flowers will appear 6-8 weeks after sowing and will remain in bloom for 6-8 weeks more.

Phacelia is an excellent flower for attracting honeybees and hover flies. This excellent green manure can also be sowed near the vegetable garden to attract these beneficial insects and help keep your aphid population under control.

Enough for 25 square metres. - 75g 

Sow March to September.  


Why sow green manures?
As we know vegetable growing takes a lot out of the soil because we remove the a portion of the soils nutrients every time we harvest a crop. Green manures are just crops we grow to dig back into the soil and provide nutrition for the follow on crop. Different plants provide different nutrients but in the main we use nitrogen fixing plants as greeen manures as they capture nitrogen from the air and release it back into the soil when you dig them in.

Green manures are also grown as a cover crop for the winter months to protect bare soil. Nitrogen and other soluble nutrients can be washed out of uncovered soil in wet winter weather and can leave your garden soil lacking in the spring. The green manure crop will protect the soil and store valuable nutrients in their roots, stems and leaves. Green manures also surpres weeds meaning you will have less trouble clearing your plot in the spring.


These plants are an easy and very worthwhile overwinter crop
to keep your vegetable garden in good health.

I bought this phacelia seed in my local farming co-op as I had bare bank walls from recent digger work to cover. The 'soil' was pretty stony in the bank and it wasn't easy to bury these seems as required. However, the seedlings duly appeared and grew pretty fast into good cover. When the beautiful purple flowers opened it was totally glorious and attracted all variety of bumble bees and butterflies. The ground cover grew to a height of about two feet in this windy seaside location. However, when the winds turned gale force the stems on the phacelia got broken and hasn't stood up brilliantly to our west of Ireland summer storms! But, hopefully it may recover? These plants are so beautiful and so admired that if they don't recover I'll be buying and burying a lot more of this seed next year! Love it for my wild seaside garden!

These work really well as a cut flower. Being able to gather bunches of sweet smelling flowers from the garden in November & December is a huge bonus in Yorkshire.

This is a great plant for a green manure, it germinates very quickly and the slugs don't seem to like it which makes it the only thing in the garden this year that escaped being chomped. I allowed mine to flower but the bees and hover flies don't seem as excited about them as I thought they would bee.

Great quality (they're covering the ground as i type...), good price. I leave them flower and they look gorgeous en masse and really attract bees and butterflies. Love it!

Hi Paul It is a very versatile plant and will grow in shaded areas however at this time of year as the trees are in leaf there will be very little moisture on the ground under a tree so this might be an issue Niall Quickcrop

Is it of any benefit to ruminants nutritionally.

Hi S. Green manure Phacelia would have very limited benefit for ruminants, it is grown more for its attractive flowers which help attract and support beneficial insects.
