Lupins

Leave it, it may come up better next year.
It could be a small variety ( there are small, medium and very large varieties) however six inches is very small, could just be a rubbishy plant.

As lemongrove says, there are dwarf and bigger varieties. My lupins are in flower now but had them a few years. As the plant looks healthy I would still leave it in the ground as it may grow bigger next year. It may need some feed. I use a liquid seaweed on my plants and veg it's brilliant. Better than anything else.

Always loved lupins as they remind me of my Dad. Never been able to grow them as slugs and snails seem to thrive on them.

No slug damage on mine. But I will give it a feed of something. Can I just put seaweed around it, as we live near the sea ?

My garden is alive with lupins and foxgloves this year. I love the old fashioned plants.

Bbbevan...seaweed itself will be too salty and won’t breakdown quickly enough to be of use.
You could turn it into fertiliser though. It’s quite a bit of (smelly) work though!!?

I posted this afternoon on another thread about the fact that I have never been able to get lupins to thrive in any garden I have had, and that DS is bombarding me with photos of his beautiful specimens. It used to irk me that you would see glorious acres of the b****y things growing wild at the side of railway tracks as you passed in a train, yet they spurned all my nurturing and attention. I have given up on them, but foxgloves love me and are at their lovely best right now!

Greyduster...me too! Only I know why they don’t last here..it’s the slugs and snails...mana from heaven to them.Delphiniums as well!

Some lupins are dwarf so it might not grow much taller. Leave it and feed it is my advice. I grew some from seed last year and planted them out this spring. They are full of flowers, so I'm really pleased. I feed all my plants and shrubs every two weeks with a liquid feed from Poundland.

My lupins become lovely silvery lace so I gave given up. Sadly my foxgloves don't flourish either!

I’ve sown Lupin seeds this year, they’ve all come up and have little Lupin leaves.
As they grow I will put them in the cold frame as they will not flower until next year, if then. Stay with your little plant, it will grow.
BTW slugs love Lupins so protect it.

My lupins seem to attract aphids rather than slugs and snails who seem to prefer the hostas. ( I have set beer traps so at least they die happy) As others have said there are dwarf varieties so maybe that’s what you have BBbevan ?
