Potty about bromeliads

Despite the fact that it can sometimes “take years” to find the spot where a bromeliad will thrive in the garden, Johanna Elder is a big fan of these tropical beauties.

Broadly speaking the Vriesea types don’t have spikes, prefer shade and need feeding to reach their full colour potential, while the Neoregelia types have spikes, like full sun and need to be starved of fertiliser to colour up.

Lynley Breeze, president of the Bay of Plenty Bromeliad Group, considers Johanna, who founded the group 18 years ago, as the best grower in the group and a visit to her Cherrywood garden shows why.

Quesnelia Tim Plowman, a tube-type bromeliad with unusual curled foliage, is being grown in full sun in a stone garden, a bold move with an expensive plant but Johanna says it is responding well.

“Often it’s a case of trying a plant here and there – it will let you know if it doesn’t like something and reward you if it does.” Conversely, she has put a couple of her bright Neoregelia bromeliads into the shade house to see if that will intensify their colour and believes the experiment is working.

“It’s heat that brings up the colours in bromeliads not direct sunlight,” Johanna says. A certain amount of stress will intensify colour too, so she adds some slow-release fertiliser when she plants Neoregelias and then leaves them alone.

“Vrieseas however, need as much fertiliser as you can give them.”

While bromeliads of all shapes and sizes and in many colours and patterns form the bulk of Johanna’s plantings her garden doesn’t feel like a nursery – there are also pony-tail palms, ferns, vireya rhododendrons, succulents, cycads and tillandsias (air plants, bromeliad cousins).

“I’m still a gardener,” she says. “It’s just that all the roses and perennials went long ago.”

Johanna first got interested in bromeliads because her brother-in-law was very involved with a bromeliad society. “The first bromeliad I came across I fell in love with,” she recalls.

After moving to Tauranga from Hamilton, husband Bruce recontoured the Cherrywood site – and the way was open to plant it how Johanna wanted.

She also enjoys growing Tillandsias and finds their clumping habit interesting, along with the fact they will grow almost anywhere. “You can throw them into a crook of a tree, hang them from hooks or stake them into a piece of ponga [tree fern]. Some are spiky, some are soft and even when they’re not flowering, they’re interesting to look at.”

Bruce built a shade house for the less hardy Tillandsias and every spring Johanna takes all the plants off the brushwood wall and sprays it for a moth that can eat the back of the plants and rot them. The indoor ones are sprayed fortnightly with a natural pest control and a weak solution of fertiliser, while the outdoor ones obtain all the nutrients they need from their surroundings.

Johanna grows most of her bromeliads in pots so they can easily be moved to find the growing conditions they prefer and so tender ones can be moved under frost protection in the winter.

Pots are presented in garden “beds” which are filled with stone mulch – the stones release the day’s heat into the night, keeping the temperature up by about 3-4degC, Johanna says. “If any of them do get caught by frost you can hose them down before the sun gets to them and prevent frost burn.

“Not all bromeliads are hardy so it’s important to know which is which.”

Her Tillandsia punctulata grows in a ponga and covers itself in flowers. “A friend said God made Tauranga for Tillandsia punctulata and she’s right. They flower here all year and the flowers can last for 10 months – they won’t even do that in Auckland.”

Johanna and fellow Tauranga group member Gil Keesing staged a display of plants at the Australasian Bromeliad Conference in Auckland in 2013 where one of the guest speakers was Elton Leme, a high court judge in Brazil who hunts new bromeliad species in his spare time – and has found more than anyone else alive.

Beautiful bromeliads

One of the world’s top breeders of Vriesea bromeliads modestly concedes that, yes, he may be among the vanguard of those creating interesting, new plants.

Andrew Maloy, who has “tens of thousands” of the plants at his Kiwi Bromeliads in Whenuapai (Auckland), believes he is the first breeder in the world to develop plants with notably wide leaves.

“I’ve consciously gone in the direction of wide leaves because, as far as I know, no one else is doing it,” he says. “There’s a bit of fashion setting involved simply because we’re working so far ahead in a very fickle market.

“Breeders have to be incredibly patient because we don’t see the results of our work for several years – from making the cross on the flower it’s six months to picking seed, then about three years before you see what you’ve got, then if it’s any good you’ve got to build up stock before it can be released to the market.”

Rare bromeliads, or those considered desirable by the market, can fetch high prices in Australia, Europe and the United States, doors that aren’t open to Andrew.

“The export of live plants is far too difficult for a variety of reasons,” he says, “but I can export tissue culture and occasionally do that.”

Andrew, who was born in Scotland, came to New Zealand in 1974 with his Kiwi wife Rhonda. A long-time member of the International Plant Propagators’ Society, he has lectured in horticulture and plant propagation, written books and articles and is a Fellow of the Royal New Zealand Institute of Horticulture.

“Bromeliads caught my attention about 15 or 16 years ago,” he says, “and vrieseas because they don’t have any nasty prickles.”

Although he is constantly selecting plants for crossing, Andrew admits that he missed the potential of one of his plants, Dark Knight.

“I didn’t think it was that great but it’s proving very popular with home gardeners because it’s very tough, almost foolproof.”

He wants his plants, which are named in series – such as the Jewel series, the Tasman series and the Kiwi series – to have attractive foliage from an early age and to be desirable texture plants.

“One of the biggest disappointments for many people is that the plants they buy don’t stay the same once they’re in the garden – but there’s often an easy answer to that.

“Too much sun will markedly change the leaf colour. Vrieseas don’t like direct sun all day. They can tolerate a bit, but prefer dappled or light shade or filtered light.”
