Tropical Plants - Australia

'Tropical garden' on the Sunshine Coast

17 years ago

Hi,

I'm about to give a friend a hand to design and plant a 'tropical' garden. This large bed will be for the most part in full sun and will have an adequate watering system installed. Tropical gardens are not an area that I'm strong in and I would very much appreciate suggestions on suitable plants.

With many thanks and happy gardening

Cheers Jan

Hi Jan,

Where do start ? :)

I guess it comes down to your friends definition of 'tropical' - get him/her to show you photos from articles/web pages that appeal, and work from there.

My own preference is to use a combination of natives and exotics, but it comes down to finding what works. The key is microclimate, and that means establishing effective barriers to sun and wind which dont completely block either (if that makes sense) - airflow through the garden is very important (as it is with any style of garden).

Good soil is particularly important in a tropical garden - palms and other tropical plants are heavy feeders and do best in a deep, rich friable soil. We all know the deal here - lots of compost, gypsum for clay soils etc. The Sunny Coast is famous for the quality of its soil, so you should be on a winner there. Colin Campbell claims that it doesnt hold water terribly well, so the compost remains a good idea.
My planting tip is to put in as many advanced palms as you can afford, as they will give the garden an established feel from the outset. From there its a case of choosing the underplantings, and that comes down to the usual practical and aesthetic criteria. Many tropical gardens have been built on a small palette of proven standards - cordylines, crotons, gingers, bromeliads and ferns - but the sky is generally the limit. Find out what works in your area and go with it - its easy to become fascinated with some of the more delicate tropicals, but old standbys like Tradescantia really earn their pay when conditions get tough. I've also had a lot of success with Diffenbachia and various Philodendrons - your mileage may differ. Layering plants, tallest at the back and smallest at the front (ok, ok .. ), is usually pretty straight-forward with tropical plants, and it will give you the best combination of privacy and shade.

Jan, I suspect that you know a lot more about gardening than I do - tropical gardens are simply another form of cottage garden, IMO. As with any mixed planting, how you group your plants determines how effective the overall vision will be. Combining plant choice with effective placement is where it's at for mine - things like water features, follies (bridges/ornate doors etc) and statuary can usually come later.

Good luck,

Artie

How does the sunshine hit my garden?

Actually, your location would be considered part of the greater San Francisco Bay Area, rather than the central valley, although your location is as much influenced by the central valley as by the bay. Your additional comment about large existing pine trees in your adjoining neighbor's yard may not be as bad as you think, unless they are to your south, in which case you will most definitely have limited sun in winter. You might find it just as practical to get yourself some half oak wine barrels and put these on your patio if this is your sunniest spot, and this size container is plenty large enough to grow tomatoes next summer, or use for winter veggies. For a winter vegetable garden, it does help to locate it in maximum sun, but if you get some of your winter veggies started now while they still get sun, some vegetables such as carrots, peas, lettuce, radishes, most root vegetables in general that are cool season growers will perform okay even with less than full sun,(but of course more is always better). You might also find that things like Alpine Strawberries do okay in less than full sun. Get yourself a copy of the Sunset Western Garden Book for general info on what cool season crops are possible in your area; as you do get frost and potentially some ground fog in winter, this will also tend to make winter crops slower growing or more subject to frost damage than locations closer to the bay. You might also consider some perennial crops such as Artichokes, which can be planted to grow over the winter also. Good luck with your endeavor, and realize that besides the shade from your neighbor's pines, there might also be a lot of moisture stealing roots, and raised beds with added top soil will probably give you better results than planting directly in the ground where large tree roots will compete with the vegetables.

FWIW...and only because the thread was already bumped. My coast redwoods saw the lowest temps they've ever seen in my garden. They only had light mulch and no special protection. Low of 6F (-14.5C) last week w/snow before the brief thaw, then lows of 3F (-16.1 C) a couple nights ago in a severe advective freeze with incredible winds, and 8F last night. 8' 'Soquel', several years in ground (5 IIRC), fully established: absolutely no sign of damage 4' 'Swarthmore Hardy'/'Chapel Hill', 3 years in ground: very minor dieback of oldest needles 2' 'Swarthmore Hardy'/'Chapel Hill', 1.5 year in ground: somewhat more extensive needle injury, still 18" 'Atlanta', 1 year in ground (first winter): minor signs of injury on a handful of needles. Would appear to be at least as hardy as 'Chapel Hill' Yes I'm aware more damage could show up later; but from my general experience other than a few special plants (olives are notorious) if there isn't sign of damage in 24h and there isn't the likelihood of bark injury (there isn't) you should be ok. My most tender experimental BLEs are showing damage. BBoy the Azara I argued with you about has about 50% foliar death...whether the stems were killed to the degree that it will be killed off I don't know yet, probably won't be sure until spring. My Escallonia 'Appleblossom' has shown rather similar damage in past cold winters and comes roaring back in the spring, so we'll see.

Hi Artie, Yes the Tresco Gardens in the Scilly Isles are fantastic. Having lived for many years in Cornwall it was only a short trip over to tresco. On the extreme western edge of the UK they benefit from the warm "Gulf Stream' water the flows up that side. This raises the air temp and means that there is a very low risk of a frost. Tresco is a haven for tropical plants and many South African plants. The gardens at Inverue in Scotland also have many plants that are seemingly out of place. Thanks Artie for the advice re the tropical garden on the Sunshine coast. Cheers Jan

I would write to Reliable Roses in Victoria info@reliableroses.com.au Those two roses are not on their list and I cannot find them on any Australian Websites Reliable Roses have quite a few Species Roses on their website so may be able to recommend two similar ones. All the best with your search.. Mary-Anne Here is a link that might be useful: Reliable Roses Catalogue
