During 3 work parties in September & October 2014, all non-native plants were removed from the Native Garden, 10 cubic yards of compost were spread on the Native & Winter Gardens, & new plants were added to both gardens.  A perennial border was created along the west edge of the Winter Garden.  Below is a list of the plants added to those gardens.

Meeting of the Border Leads

On 4-21-14 the Border Leads (Dale Herter, Kate Faulkner, Jordan Jackson & Joyce Moty) met in the border to review plans for the improvement of the Native Garden.  It was agreed that most of the existing plan for the Native Garden Improvement Project, proposed in July 2013 & approved by the Bradner Leads in August 2013, would begin to be implemented in the fall of 2014.  We decided to change the plan to keep both Mahonia 'Arthur Menzies' & prune them.  We agreed that all other non-native plants would be removed from the Native Garden & moved to new sites if possible.  We considered adding new planting to the street side of the Native Garden consisting of Evergreen Huckleberry (Vaccinium ovatum) & Creeping Mahonia (Mahonia repens) both medium-sized shrubs.  Jordan suggested adding Pacific Coast Native Iris (Iris douglasiana & hybrids) & Beach Aster (Erigeron glaucus) to the plant list for the dry & sunny strip along the path.   Joyce offered Camas (Camassia sp.) & False Lily of the Valley (Maianthemum dilatatum) from her garden for the project.  Jordan offered Red Elderberry (Sambucus racemosa) & White Flowering Currant (Ribes Sanguineum 'White Icicle'). 

We agreed that compost for the new planting the Winter Garden should be added as soon as possible to allow it to settle & break down to become less acidic, before planting in the fall.  Jordan offered to draw new plans for both gardens shortly before planting begins.  Different approaches to irrigation were discussed without agreement.  There was general agreement that a list of rules should be made to guide improvements to the Ornamental Border, such as using drought-tolerant plants, researching the size & shape of shrubs before planting & planting large shrubs well away from the path.

Winter 2014

Acer buergerianum (Trident Maple) & Acer griseum (Paperbark Maple).

Sheet mulch.

Sambucus caerulea (Blue Elderberry).

Chionodoxa luciliae (Glory of the Snow)

Drimys lanceolata

Euphorbia characias & Helleborus argutifolius (Corsican Hellebore).

Helleborus x hybridus.

Magnolia stellata 'Rose King'.  All photos were taken on 3-18-14, 2 days before the 1st day of spring. 

During the fall/winter of 2013/14 some general pruning was done in the Ornamental Border.  Most notable was the transformation of the Sambucus caerulea (Blue Elderberry) in the Native Garden.  The 2 lowest limbs of the Acer buergerianum (Trident Maple) in the Winter Garden were removed, which made room to plant shrubs between it & the Acer griseum (Paperbark Maple) & also gave the latter more room to expand.  There was a work part in early March 2014, during which the weedy area north of the Shade Garden was sheet mulched & a think layer of compost was spread on the Native Garden.
