GUNNERA MANICATA – THIS GIANT ORNAMENTAL RHUBARB SHARED THE EARTH WITH THE DINOSAURS! $2.10

SOMETHING AMAZING! GUNNERA MANICATA ONE OF THE BIGGEST LEAVES ON THE PLANET! GROW YOUR OWN UMBRELLA! POT THEM TO KEEP AT A MANAGEABLE SIZE!
It’s a vast great brute of a thing with leaves up to 6ft across. Giant Rhubarb describes it well! In pots it grows much smaller though really does look luxurious!
If you have a spot in the shade you want to cover, these will cover it well and with a great eye-catching ability!
Considering its tropical origins, it’s odd it grows so well in the UK and Australia but grow well it does. The leaves can go from nothing in August to up to 6ft across by December but it’s important to understand that they can only perform if they have water available to do their trick and will be encouraged if they’re in the shade of trees.
The combination of shade (encouraging the leaves to be drawn up to the light) and water is essential if you want a bit of drama in the garden. Also, a bit of time. The larger you plant them, the better but they still need a few years to reach maximum size.
Given the right conditions, they can get so big that you can comfortably walk underneath the leaves in the summer.
The flowers are huge towers and they consume considerable energy. They’re all part of the fun but if you really want maximum sized leaves, remove them. The energy can then go into leaf production rather than peculiar looking flower production. Up to you. Of course if you wish to collect seeds you need to allow the flowers to come to fruition.
The large leaves unfurl in spring and sit on erect, hairy stems.
It bears spikes of enormous greenish/red flowers in spring.
An amazing foliage plant that loves the shade and having its feet wet, so plant it on pool sides, boggy areas and next to ponds.

Grow Notes
It prefers a shady spot with wet fertile soil but ensure that the soil remains well-aerated. They need available water but will not survive in a bog. Near water with a few roots dipping in, not right the way in the water, is best.

Marginally frost hardy.

Remove dead leaves and flower heads and ensure adequate moisture.
If your winters are cold then take the last of the leaves and make a thatch cover for them to protect from the worst of the winter cold.

Sow
Sow in Spring or early Summer. Sow seeds 2.5cm apart on top of the soil in a tray filled with moistened compost mixed with vermiculite or perlite. These seeds need light for germination so you can simply lightly tamp them into the soil or gently cover them with a fine layer of sand. Cover the tray with plastic, removing once a day to allow air into the area and mist to keep it moist if soil is drying out.

A constant heat is helpful and will speed germination, so heating pads will be helpful if you are not getting temperatures between 20-25°C daily.

Place in a bright spot out of direct sunlight.

Germination
15-60 days at 20-25°C.

Maturity
They will need a few years to reach maximum size.
