It's nice to have a white garden, for enjoying on moonlit nights. What dry climate plants show up well in the moonlight?
Irises can be tough, once established. I saw a whole paddock of white iris growing outside Grenfell, once, in a state of abandon. They'd multiplied by themselves, for decades, somehow, without much rainfall or care.
African Daisies can be tough. I've noticed that. The white-petalled ones show up well at night. You can grow them from cuttings in a jar of water, from late autumn through winter. Just keep them on your window sill, and change the water once a week. Plant the rooted cuttings out in spring, and water them well for the first summer, so as they become established.
Wormwoods are a must-have. They are silver-leafed, and show up well in the moonlight. Artemisia arborescens is probably the toughest wormwood of all. You'll find it growing near the ruins of abandoned farmhouses. It's as tough as old boots. It has a nice scent, too, when you crush the leaves. It's soft to the touch, as well.
Again, you can grow it easily in jars of water indoors from autumn through winter, to be planted out in spring. Alternatively, you can cut dozens of good-sized cuttings in a wet winter. Get around your grounds with a long metal tent peg, and bore deep holes as you go. Fill each ''drilling'' with a wormwood stick, and poke the dirt back in around it, as best you can. Pour a bucket of water on each cutting, and then forget about them, leaving them to root--or not!!--with only the wet soil and any further rainfall to get them through. If you are lucky enough to have a wet winter, and a wet spring, some of those cuttings will root, and, indeed, some can even, somehow, survive a first summer, on rainfall alone, without being tended to much. Of course, it depends on exactly how much rainfall they get in that first summer that will guarantee whether they make it or not. They'll look shocking, for that first year, but if they make it through, alone, you'll have them for years and years as friendly silver companions. I have dotted the sticks around my garden, in wet winters, for years now, and am now lucky enough to have many of them in various stages of growth--all over my property. Silvers, blues and greys are restful on the eyes, in the daytime, too.
An interesting thing about wormwoods is that certain birds, including currawongs, seem to use the leaves as a medicine--possibly an anthelmitic. They mash the pecked-off leaf with water, in the shallow part of the stream, or a birdbath, and then sort of gargle it around in their throats. I don't know if they swallow the juice or not. I suspect so; that they purge themselves, somehow, with it. This self-medicating, by birds, is interesting, and reminds me of Yogi Ramacharaka's amusing account of clever Indian ibis giving themselves rectal douches with their very long beaks.
Senecios are another silver-leafed plant that shows up well in the moonlight. They are very easy to grow from cuttings, too, directly into the soil. Go to a well established senecio, and lift up some of the older branches around it that have been lying on the ground--the ones with all rotting leaves on them. Look carefully, and you'll find that the branches have roots on them where they were moist and touching the soil. Clip off some of those rooted branches and plant them out, and they should do well. Alas, senecios would appear a little more thirsty than are their relatives, the wormwoods, but they are still pretty tough. You can keep them hanging on through a drought summer with a little extra water, and mulching will help, as well as soil improvement at planting time. Senecios come in different colours, so look around. You can get them with pink blooms, or blue- or lemon- coloured. They are usually grown for their silver leaf display, but if you plant masses of them, the floral display is very nice. As I write this, I have hundreds of pink senecios giving a lovely display--silver leaves and pink blooms. Very nice. Again, soft to the fingertips as well. (Touch should always be a consideration in any garden!)
Silver-leafed wattles are a must for a moonlight ''white garden''. Acacia podalyriifolia is very tough, and gives plenty of strong yellow colour for the daytime cottage garden, as well. Check out your local forestry commission nursery for other useful silver/grey wattles, of varying sizes and shapes and habits.
Other tough plants that spring to mind, for a moonlit white or silver garden, are:
Agapanthus--these bulbs are very tough, and the white variety will show up well in the moonlight.
Allium--quite a tough little bulb. Spring blooms can later be dried, and used as perpetuelles.
Almond blossom--nice white blooms from late winter to early spring. Honeyeaters like almond blossoms, as well. Look fantastic on moonlit nights. Cockatoos will come to crack the nuts open for food.
Belladonnas--look around bulb suppliers for the white variety. Beautiful perfume, and make a change from the ubiquitous pinks.
Freesias--white- and cream-coloured ones give nice perfume in spring.
Horehound--nice fragrant little silver/blue/grey herb. Very tough.
Jujube--lovely silver leaves. Exquisite perfume from tiny orange flowers. A must. Very drought resistant.
Lucerne trees--nice white, slightly fragrant blooms in spring. Honeyeaters value them. Some trees are more drought-resistant than others, so save seeds of ones in your district that are doing well in abandoned places.
Olive--tough tree whose leaves have attractive silver underlinings.
Plum blossom--nice source of white spring blooms. Most plums are pretty tough. You see 'em growing by roadsides where people tossed the seeds from car windows.
Tritelias--small bulbs that give white star-shaped flowers in spring.
White bougainvillea--remarkably drought-resistant, once established, but you'll probably opt for a flaming purple one, instead, to light up your garden in the daytime. I wouldn't blame you!
White jacaranda--not as showy, in the daytime, as a purple jacaranda, but nice on a moonlit night, with white petals on the path. Very tough trees, once established.
White oleanders--give good drought resistant summer blooms. Very tough, indeed!
Moon Wallabies
Imagine walking in the moonlight, with Willie Wagtail singin', as he's wont to do on full moon nights. Thousands of frogs are croakin' down in the reedy ditches by the railway line. You walk in your garden and albino wallabies are shimmering in the light. The white horses in the field are galloping. The African daisies are clearly visible. The wormwoods shine silver....
