• A New Zealand inspired California rock garden

     In 2009, I visited my sister in New Zealand and on one weekend trip we drove down to the city of Dunedin on the South Island. There, before breakfast and while Karen’s hubby slept in, the two of us walked over to the Dunedin Botanical Garden nearby our hotel.

    The most impressive garden for me was the rock garden. We walked along a decomposed granite path skirting the hillside above the main gardens. All along this path were rock-edged pockets jam packed with cushiony alpines, dwarf conifers, and low-growing, mat-forming plants.  It was simply charming.

    Lichen-covered granite rocks formed planting pockets in the rock garden,…we loved the colors and fine textures of the plants. Form and shape of the plants seemed to be most important and effective here and we oohed and ahhed our way down the broom-swept path.

    This garden impressed me so much that I was determined to build myself one near the huge granite boulder down the hill from the south end of the house. After Larry brought down a load of rock for my birthday,  a friend, Cheryl came to help lay it out.

    The boulder dominates the garden and the manzanita may need to be thinned to be in
    proportion.  We laid out an edge and formed smaller pockets to be filled up hopefully by lush, mat-forming plants someday. It would be nice to replace the log steps with more rock at some point. A few succulents were planted at this time last year, some that were transplanted from other areas.

    The next step was to build a rock and log path along one edge and lay down gravel.  It’s very steep here and something needs to stop one from running down hill. Transplants from other areas were planted while considering what plants to buy. Cold hardy succulents are a must when the temperature goes down to 20 degrees routinely. So far the ones planted have been from the neighbors or others who live here since many of my succulents brought from So Cal when we moved melted and turned black in the cold of the first winter.

    Here is another view of the Dunedin rock garden. For future, I’d like to add some dwarf conifers, maybe a Chamaecyparis and dianthus combination like this.

    Our own native Dudleya would be a great addition and there are some divisions in the works. Succulents are a perfect choice and so far they’ve mostly been for patio pots. This garden will allow them to spread out and grow into their natural size and shape.

    This is how the rock garden looked this summer one year after planting. The pink is Clarkia amoena blown over from the meadow across the path.

    More rock areas in the garden

    I dodged the bulldozer building our septic lines to rescue many of these rocks above. It all had nice squarish shapes perfect for steps. Two broken blocks of concrete from somewhere add a bit of age.  Underneath the pedestal is a half-barrel ‘pond’ liner set into the earth and water flows up through and drips out of the terracotta container.  At the top of the photo is creeping thyme.

    Here is another area with a load of rock needing to be laid into a permanent arrangement. Not a rock garden per se, but the rock will edge the planting bed. This area is meant for mostly CA natives. Centranthus, the dark pink, isn’t invasive here and is so attractive and deer resistant, I may let it stay. Other plants here are coffeeberry, goldenfleece, Big Sage, Artemisia tridentata and California fuchsia.

    A future trip to our native plant nursery will be a highlight this Fall. Fun!  And as always more rocks could be used whenever we find them here.

      I had to laugh, only hard core gardeners would get excited about receiving a load of boulders for their birthday! 😛 Your rock garden is filling in nicely though. I wouldn’t have thought about Zauchneria for a rock garden, but this time of year I bet the variety ‘Everett’s Choice’, with it’s low growing habit, and profusion of flowers would look fabulous! I can’t wait until fall. We did a lot of clearing and tidying up this weekend, and now I’m itching to get planting!!!

      Quite a collection you have there! You’ve done a beautiful job.

      Thanks, Clare, yes, it’s true. Rocks is a very appriate gift for a garden, unless you can get a truckload of mulch. I’m so glad you think the ‘Everett’s Choice’ would work. I have one that hasn’t done well on a clay bank. This is the first time I’ve had success with CA Fuchsia and I’m thrilled to see blooms on the ones planted last spring.

      Thanks, Katie.It’s been fun to write it all out and see the progress. I’m also looking forward to some fall planting!

      I will, thanks, Bom, I’m planning to add a few more plants and will post more as it grows!

      That last picture is hilarious! Did Tractorman lift that boulder with his own two hands, or did you need to help a bit? Hahaha!
      Your garden really is a testimony to your hard work and planning, Sue. You have created a valuable legacy to hand over to future generations to enjoy and, hopefully, share your passion and vision in maintaining it and building on to it.

      hahaha! You noticed that, huh, Desiree? Thank you so much.
