Rhubarb!

I have never heard of growing rhubarb from seed. You usually get a crown from a neighbour . I had to split mine last year as it doesn't like to be cramped. It goes too quickly to flower. It likes to be kept watered but it is remarkably unfussy and just gets on with it at the bottom of the garden. Don't pick all the stems. Make sure you leave a few for the following year..

We have rhubarb in our front garden and no it doesn't look funny but it is planted against a wall. The front garden has most sun in the morning and then shadier in the afternoon. I don't ever water it. Don't be as lazy as me and wait until the leaves are enormous and then cut it. It is so hardy and gives me loads to freeze each year as well as to cook with. My DH also grows it at his allotment so I have to give loads away and it is always appreciated.

Don't worry where you put it. Rhubarb looks lovely and lush when in leaf.
I was encouraged to grow anything anywhere after seeing the glorious parterres in the Tuilerie gardens full of ... beet chard and runner beans! I once bought some seeds in Paris and mentioned to the vendor that the beans were delicious. He laughed merrily, and I could see his mind going "ces anglais!"

I ve run out of room and have potatoes amongst the flowers in my front garden who cares they re all plants

Unless you're patient, I'd buy a one year old crown. As Redhead wrote, you should wait a year before picking, to allow the plant to build up.

I have one plant in my very small garden, which gets sun for about half the day. It produces enough for me to pick a few stems maybe twice a week, which I stew and have with yoghurt for breakfast. It freezes well, if you do happen to have a glut.

The biggest problem in a front garden is the big empty space when it's dormant. I guess you could underplant it with small spring flowering bulbs.

I stayed in a cottage in Wales there was rhubarb in the front garden in among the shrubs. I was delighted throughout the holiday making crumbles with it. I have never grown it from seed but from crowns of Timperely early. Mine in my raised vegetable beds it does take up a lot of room but I love rhubarb. I know you are not to pick first year and the leaves are poisonous. I pick until early summer then trim it down. Any advice on gardening is good from Allotment Garden website based in Wales. I recommend D G. Hessayon the vegetable garden book.

I grow rhubarb in a cramped spot by my shed it’s in the sun from early morn till lunch time and it’s not spectacularly successful but supplies me with enough for myself. I’ve also thought of planting some in my front garden I don’t think it matters to be honest what people think if it works.

Why not google “growing rhubarb” to get expert advice or go onto the gardener’s world website and do a search.
Ideal position is full sun.
