I have been given some Phacelia seeds, I don't know what type of Phacelia, but apparently they are helpful to bees. What I need to know is how high do they grow and do they spread. Can anyone help? I think it is time to sow them now.
This is good for bees, is this the one you mean? I remember it as about a foot tall but haven't grown it lately.
It's good as a green manure, too. When it's finished flowering, dig it in and it will help to improve your soil.
There is a quite in depth article on the telegraph about Phacelia...
Growing anything from 0.5-1.5m (20in-5ft) tall, with feathered, fern-like leaves, it has truly beautiful flowers that unfurl, rather prawn-like, in purple. (link above).
I sowed my whole front garden with Phacelia tanecetifolia about two weeks ago, it germinated within a week or so and is now ready to thin out. The seeds were from Kings seeds and only cost £1.50. Actually I only used half a packet, so 75p. I shall dig some in as green manure as the seaon progresses to make room for the pumpkins that I shall be planting out later, but will leave at least a couple of rows by the hedge for the bees.
Actually on second thoughts I may leave it all and let the pumpkins fight it out for themselves.
