I bought a herb fennel plant in our first year as allotment holders – I hadn’t realised quite how readily it spreads its seeds! I now have multiple plants, but unless they’re in the way of other things I’m trying to grow, I let the new fennel plants grow too.
Normally the fennel reaches about 5 feet tall, but this one seems to want to smash that completely. It’s already taller than me when I stand on the pathway – if I was to stand at ground level, I think it’d be getting on for a foot and a half taller than me!
We don’t get many birds on the allotment site, so I don’t know if the seeds would be something birds would eat. However the fennel flowers do tend to attract the insects; of course as I went to take the photo, they all flew off!
