It’s been a little over 6 months since Michelle Bond of Thumbellina Gardens in San Francisco installed this living wall in her client’s back yard. You can see details of the installation here. She recently forwarded us updated images of the wall, and gave us more details about what kinds of maintenance she’s doing. It seemed like a good time to revisit the project in a new post.
Overall both Michelle and the client have been very happy with the wall’s progress. While it looked good when installed, it has had time to start growing in.
Michelle recently sent over a plant list for the 45 different varieties that she used. Many have asked, so we figured we’d just print the whole list:
AEONIUM MINT SAUCER, ACORUS GRAMINEUS, ALOE- SUB- SERRISA, ADIANTUM PEDATUM, BLECHNUM, CAMPANULA PORCHARSKYANA, CAREX FRASERI, CRASSULA,
CISSUS RHOMBIFOLIA, CUPRESSUS MACROCARPA, DAPHNE CNERUOM, DRYOPTERIS ERYTHROSA, DAVALLIA TRICHOMANOIDES, EUPHORBIA- SUB ANTHERICUM SANDERII, FATSIA JAPONICA, GLECHOMA HEDERACEA, GAULTHERIA PROCUMBENS, HEDERA HELIX / IVY, IRIS – PELLEA ROTUNDIFOLIA, IBERIS SEMPERVIRENS, JUNIPER C. PROCUMBEMS NANA, LOMANDRA LONGIFOLIA, FUCHSIA, NEPHROLEPIS CORDATA, OPHIOPOGON JAPONICUS, OXALIS OREGANA, PELLEA FALCATA, POLYPODUM- SUB- ERIGERON, POLYSTICHUM TSUS SINENSIS, PLECTRANTHUS, POLYSTICHUM MUNITUM, SUB-TRADESCANTIA, PYRROSIA / STAGHORN FERN, SEDUM DASYPHYLLUM, SELAGINELLA / MOSS, SILENE UNIFLORA, SOLEROLII / BABY TEARS, SEQUOIA SEMPERVIRENS, SAXIFRAGA, SUB- ALCHEMILLA, VACINUUM- SUB SESLERIA, CYMBALARIA MURALIS, VRISEA, VIOLA HEDERACEA
She commented that there were three that didn’t do well – the Serissa, the Vrisea, and the Alosteria. Other than that, everything has really taken off.
We also asked her about maintenance levels. This, not unsurprisingly, is one of the most frequent concerns of the designers we have asking about living walls. She responded that they trim about once a month, check the pH of the fertilizer solution (in the fertilizer injector system) every two weeks, and change the fertilizer mix every 4 months. They’ve tested the pH of the soil once so far (in 6 months), and intend on maintaining that schedule. Clearly what she’s been doing is working.
We’re hoping to enter this for a few awards this year. Such a fantastic installation shouldn’t go unnoticed! We’ll post more images as we get them. Pretty soon the entire grid system will vanish behind the plants!
