Hallson Gardens

I have a plant which was sold to me as Gunera Manicata. It stands beside the pond in a large hole lined with plastic to keep its feet wet.

The coming spring will be its 6th so by now I should be expecting large tall leaves, but so far it has been disapointing, growing to about two feet with leaves about two feet each. The root ball when I dug it up to insert the plastic liner weighed nearly 200 lbs, and it has about 15 flower spikes. It has also produced two seedlings which have grown to about the same size.

I'm wondering if one of two factors could be true.

1. It is short of nitrogen, the dark green leaves would indicate to me that this is perhaps not the case.

2. It is not manicata. I'm wondering if there are smaller gunneras which look like manicata in everything but size.

Can anyone help please?

There are smaller Gunnera species. That's about all I can tell you. There are other Gunnera growers here...hopefully they can give you more info!

GF, go down about 15 or so posts on this forum. Sam has som spectacular ones. Bet he can help with your questions.

Sam's on Holiday, right now.... so ya might have to wait a week or so, if he doesnt check in. Why dont ya leave him a post asking for his help? It might make him feel he's been missed.

they are greedy feeders, and like to be in soil rather than a tub or or restricted liner.

do you cover it each winter? the root is quite hardy, but the crowth stems are not, so if last years growing point died a new one will be small each year, that might account for a small palnt with a large root ball.

It is possible your position is stunting its growth, or you have a small form of Gunnera. If the position is a bit dryish, a bit sunny, a bit short on lashings of fertility, Gunnera can be a bit insipid

The most impressive stands of Gunnera I came across where usually in valleys with high trees around them, unlimited well decomposed leaf compost, abundant moisture

You might look up photographs of the gardens of Heligan, Sheffield Park gardens, Hodnet Hall, to get some idea of how they like their feet in the shade and their heads in the sun...

This is my own Gunnera
They need lots of water and freedom for the roots to develop
