Dry Garden Improvement Project

The Dry Garden & the Butterfly & Hummingbird Garden remain the most problematic areas in the Ornamental Border.  It is pointless to do anything with the Butterfly & Hummingbird Garden until Seattle Parks & Recreation removes the trees there.  That leaves the Dry Garden as the most obvious area for improvement.  I propose that we remove the Acanthus, which isn't doing well in that location & has been discussed, as well as the Kniphofia & Phygelius, which are growing out of control.  In this area, including the area on the north side of the stair (which is a bit vacant) I propose we plant some of the following drought tolerant plants.

Shrubs
Arctostaphylos columbiana (Hairy Manzanita) Arctostaphylos densiflora (Vine Hill Manzanita)
Cistus ladanifer (Crimson Spot Rockrose) Cistus purpureus (Orchid Rockrose)
Dorycnium hirsutum (Canary Clover)
Erica arborea 'Estrella Gold' (Tree Heath) Erica australis (Tree Heath)
Myrtus communis (Common Myrtle)
Phlomis fruticosa (Jerusalem Sage)
Rosa rugosa (Sea Tomato)
Yucca filimentosa 'Color Guard'

Perennials
Achillea millefolium 'Terracotta' (Yarrow)
Asclepias speciosa (Showy Milkweed)
Erigeron karvinskianus (Santa Barbara Daisy)
Eschscholzia californica (California Poppy)
Euphorbia rigida
Perovskia atriplicifolia (Russian Sage)
Panicum virgatum (Switch Grass)
Stipa gigantea (Giant Feather Grass)

Groundcovers
Hypericum cerastoides
Lithodora diffusa
Sedum, various species
