ALAN POWER: Thanks for downloading this garden cutting

from the National Trust. I'm Alan Power Head Gardener at the

Stourhead estate in Wiltshire. In these shorter programs, I'm

focusing on a particular aspect of our work.

I'm in the walled garden and I'm about to go into the Pelargonium

House, which is a really important part of the walled

garden, but also a really important part of the history of

Stourhead. It tells the story of one of the great owners of the

property in the 19th century, Sir Richard Colt-Hoare.

Richard Colt-Hoare was an amazing man and without him,

Stourhead wouldn't be what it is today. He looked after his

grandfather's original creation, which is the wonderful landscape

garden at Stourhead.

There's nowhere better really to read how fascinated Richard

Colt-Hoare was with plants than in the Pelargonium House.

I started at Stourhead over 20 years ago and when I first

started here, this greenhouse wasn't standing. This collection

didn't exist. So I've watched its evolution over the time and

I've watched us learn from the different types of plants in the

collection. Now I'm off into the Pelargonium House to see Emily

Utgren. She's one of our gardeners at Stourhead.

Hi, how are you doing?

EMILY UTGREN: Yeah, good thanks. Good thanks. I'm just doing a

little bit of picking over of the Pelargoniums.

There's quite a lot of dried leaves that we like to take off

and make sure that we display the Pelargonium in the best

possible way. These are South African plants. So you can

imagine the conditions that they'll need almost a little bit

deserty, nice and dry but also quite cool.

I take off any flowers that are even on the way to going over to

finish flowering so that we get a continuous display of flowers,

which we do actually achieve somehow throughout the season

with the with the help of a little bit of feeding with

tomato food to keep them flowering. But also the picking

over and the controlling of any wee beasts is always vital.

ALAN POWER: And it's interesting, isn't it? We

constantly now refer to them as Pelargoniums and a lot of people

out there will know them as the Geraniums you grow in your

conservatory, you know, and particularly the zonal ones and

they're called zonal ones because of the patterns on their

leaves.

But even standing in front of the collection that we're

looking at and they're all completely different. Yeah,

we're looking at zonal ones, cut leafed ones. But the unique

thing I suppose about the collection that Richard

Colt-Hoare developed was that they were the predominantly the

scented leaf Pelargoniums.

EMILY UTGREN: Yeah, the chocolate, almost smelling ones,

but mint chocolate almost. And of course, some of them are even

used in cooking

ALAN POWER: And they used to lie the leaves in the bottom of the

sponge cake tin, didn't they? And then the flavour would,

would ooze up through the cake.

EMILY UTGREN: Ooze is a good word, isn't it? Yeah. Yeah.

Yeah. Can you imagine when that's cooking? And you in,

from, on a, on a cold day in October, you know-

ALAN POWER: And I've eaten a geranium cake flavoured with the

scent from the leaves up through it. And the lady who made the

cake topped it off with cream. This, it was a really nice cake

and then sprinkled over the top of rose petals. No way you can

eat the rose petals as well and it was just so nice. My dad

wouldn't eat it. He said I'm not eating roses, but it was really,

really lovely this collection of plants.

So I think as gardeners, you know, we, I know lots of people

say, but we genuinely never stop learning. I mean, we're looking

at a great variety of plants here and, you know, most

Pelargoniums are fairly easy to take cuttings from, you know,

you can strike cuttings fairly easily. You pick the right time

and you pick a very healthy growing tip. But actually some

of them have been a real, real challenge, for example.

EMILY UTGREN: Oh my goodness. Yeah. Triste a, is a species of

that we grow here and it's a proper desert dweller. So in the

summer it will disappear and look dead.

ALAN POWER: It's not the most attractive Pelargonium is it?

EMILY UTGREN: No. But when it gets going, when it's, you know,

when it knows that the, the South African summer's over, it

will spring to life. But you can't get cuttings off it. They

don't have that kind of stem. So you need to go for- for seed.

ALAN POWER: And over the years, you know, we've been, we've been

learning from that and they become more and more

challenging. Interestingly enough, some of them are

pollinated by bees and you know, the other insects that come

through, but Triste is a moth pollinated one. It's night

scented. So it's moth pollinated and we've learned all of these

things over the years.

So developing this collection over the last 20 years has been

fascinating.

1997 was a key point in the, in this collection, we discovered

that there was an appropriate Victorian greenhouse being

demolished in Sussex. So we were offered it, we brought it back,

restored it, painted it, rebuilt it and it's here today and it

feels as if it's always been here.

EMILY UTGREN: And It works better than most greenhouses I

know. They knew what they were doing. So the design itself in

terms of air circulation, ventilation, all of these

things, it works.

ALAN POWER: And all the winding gear works and-

EMILY UTGREN: It's, it's so cool.

ALAN POWER: There was kind of champions of greenhouses back

then and this is a Foster and Pearson and they were, you know,

they were up there with the great greenhouse engineers of

the time.
