The Wonderful World of Aloe

Probably because our winter has been so dramatic every time I see the brilliant flower spikes of an aloe plant glowing brilliant red, yellow and orange I marvel. Beloved by hummingbirds and sustainable garden aficionados alike aloes are easy to grow. So easy that a couple of these tough-as-steel succulents are growing right out of the cracks in a gas station parking lot in town and blooming without any supplemental water or care. How?s that for bullet proof?

Aloe ferox

Our Mediterranean climate is perfectly suited for the exotic looking family of Aloes. Some hail from the Arabian Peninsula and Madagascar but mostly they are native to South Africa. The spikes of their showy flowers supply much needed nectar for hummingbirds at a time that not much else is blooming.

There?s a variety for any space, large or small, container or tree-like. Here are a few of the types I?m seeing blooming right now in our area.

Aloe ferox or Cape Aloe grows best in full sun but tolerates a wide variety of growing conditions. They can thrive in very dry conditions or grow in an area that receives regular irrigation- a good trait given our recent wet winter. The foliage is hardy to at least 20 degrees and the winter flowers down to 24 degrees. Cape aloe grow to 6 feet tall and 3-5 feet wide so plan accordingly if you plant one of these spectacular reddish-orange to orange succulents. Cape Aloe occupies a many habitats in it?s native Cape Region of South Africa and is listed on the endangered plant list.

Aloe arborescens – Torch aloe

Torch Aloe or Aloe arborescens blooms also in fall and winter. The bright yellow or red flower spikes cover this large clumping variety. This species has recently been studied for possible medical uses similar to the well known aloe vera plant. It?s the only other member of the Aloe family that is claimed to be as effective. It can survive much lower winter low temperatures than aloe vera.

Aloe vera has been grown for thousands of years in tropical climates. It is one of the most widely used medicinal plants on the planet. As a houseplant make sure the pot has plenty of drainage holes as they cannot tolerate standing water. Let them go completely dry between waterings and grow them in the very bright light of a south or west facing window.

Aloe maculata

The Soap Aloe or Aloe maculata is so tough that it can survive just about anywhere. Besides the parking lot I mentioned earlier it?s growing in my Bonny Doon garden that receives no winter sun at all. The gritty soil here drains quickly which helps them survive given the 124 inches of rainfall received so far this winter. My Soap Aloe aren?t blooming right now but others in better growing conditions are sporting showy flowers atop tall, multi branched stalks in colors ranging from red to gold. Once established this succulent needs only occasional water to look good. They grow in partial to full sun. The foliage gets 18 to 24 inches tall with the bloom spikes reaching 35 inches tall.

Every garden should have a variety of aloe to feed the hummingbirds in winter.

Succulents: One Solution for the New California Garden

According to Weather West, a California weather blog authored by climate scientist, Daniel Swain, the latest seasonal predictions do not inspire a great deal of hope that the coming winter will bring drought relief. ?A substantial La Nina event no longer appears to be in the cards. If it?s present at all, it will probably be quite weak.? Seems that persistent West Coast winter ridge may just rear its ugly head again. Even if subtle shifts in the large-scale atmosphere pattern lead to a different outcome here, our persistent drought is still on the table.

More and more people are asking me to update their landscaping to use less water and be lower maintenance. Many want a more modern look and what could be more architectural and clean looking than a succulent garden?

Converting to a low water landscape requires careful planning and design to achieve the look you want. You need to evaluate drainage patterns, soil types, slopes, areas of sun and shade and building locations. Hardscape features, such as patios, paths and decks require no water to maintain and by selecting permeable materials such as porous pavers and gravel, rainwater can infiltrate the ground. Large boulders can be used as accents.

Next comes the fun part- plant selection. In choosing the best succulents for your garden think about if your area gets frost during the winter. Does it have protection from a building or evergreen tree or do you live in a banana belt that rarely freezes? Are you planting in sun, shade or a combination?

In addition to the hardy succulents like sedum and sempervivum many showy succulents need only a bit of protection during our winters. Aeonium decorum ?Sunburst? is one of the showiest species with spectacular variegated cream and green 10″ rosettes. It looks terrific planted with black Voodoo aeonium. Aeoniums do well in our climate as they come from Arabia, East Africa and the Canary Islands where winter rainfall is the norm.

Echeveria grow naturally in higher elevations of central Mexico to northwestern South America and so also do well in our our cool wet winters. ?After Glow? is frost tolerant and looks to be painted with florescent paint. There are spectacular hybrids being developed every year. These are not as hardy as the traditional hens and chicks but well worth the effort to find a place where they can survive a freeze. Frilly ?Mauna Loa? sports turquoise and burgundy foliage while Blue Curls echeveria looks like an anemone in a tide pool.

Aloes from South Africa and Arabia are old world plants. Many, like the medicinal aloe vera, are frost tender, but other such as the tree-like aloe plicitilis are hardy down to 25 degrees and look great either in the garden or in pots. Did you know the Egyptians used aloe in the mummification process or that there are no known wild populations of aloe? In South Africa an aloe called ferox is used in the same way as aloe vera for burns and stomach problems.

To ensure success when growing succulents, make sure your soil is fast draining. Our winter rains can rot even the toughest plants when their feet sit in soggy soil. Add sand, gravel or pumice to your soil or plant on mounds to increase drainage.

Save Water with a Dry Lush Landscape

In all the years I?ve been a landscape designer I?ve never heard anyone say to me ?I want my garden to look like the desert.?? Using California native plants along with appropriate low water use plants from other Mediterranean dry climate areas can save water and look lush at the same time. We live in an area naturally rich with trees and shrubs and wildflowers that survive on seasonal rainfall. Here are some ideas to give your landscape a lush look while saving water.

There?s no better place that showcases a dry lush landscape that my friend Richard Hencke?s garden in Scotts Valley.? Doc Hencke has been at this gardening business a long time starting when he was a kid in Texas and Oklahoma. I am always inspired whenever I visit his garden and come home with a car full of plant starts from his greenhouse. He?s a propagator extraordinaire who loves to share and is a good friend.

On this day I also wanted to see his new raccoon-proof pond and surrounding landscaping. There calandrina starts are settling in nicely. They haven?t started blooming yet but will soon with those neon-pink flowers that sway above the plant on long stems. This spectacular Chilean perennial is long blooming and perfect for a dry garden or difficult spot like a parking strip or hillside. It will suppress weeds as it grows, quickly spreading into a dense groundcover. Nearby is another bed filled with aeonium, sedums, kalanchoe, baby toes and other succulents designed by his wife, Judy.

Doc Hencke?s garden is comprised of a couple dozen different areas or garden rooms. He?s been enjoying discovering new succulents and adding to the new dry lush hillside. He?s growing several varieties of aloe, cordyline and yucca along with douglas iris which are doing fine given the same irrigation as the rest of the dry hillside. Blue Chalksticks or senecio mandralis border the path and their long bluish-green fleshy leaves look great near the red cordyline.

The secret to a lush look is to group plants into a vignette of complimentary elements. A vignette is a brief but powerful scene. Garden vignettes can be more than just plants. Doc Hencke?s driveway garden is a good example. An array of textural plants is combined with a weathered teak bench, richly colored, glazed pots filled with the architectural strappy leaves of phormium and a recirculating water fountain to complete the scene. The blue stone retaining wall is the perfect compliment to the blue and gold succulents that grow in the nooks and crannies.

A dry lush plant palette could also include plants such as Little John bottlebrush, dietes ?Katrina?, Festival Burgundy cordyline, Hot Lips salvia, Variegated dianella, Amazing Red phormium, Icee Blue podocarpus, phlomis, Southern Moon rhaphiolepis, Gulf Stream nandina and Cousin Itt acacia.

A visit to this amazing garden wouldn?t be complete without admiring Doc Hencke?s prized Sand plum which he swears is the tallest in the country. Also called Chickasaw plums they are found naturally on sandy prairies in Oklahoma and Texas where they are very effective in stopping blowing sand. Wikepedia states this early blooming plum grows to 20 feet tall and Richard?s is about 30 feet tall. Just another in his long line of horticultural successes.
