Kartes Feb 2023: Suggestions for a more resilient landscape (updated after site visit) Streetscape If possible, replace sod along Sievers-Duecy with a less thirsty, lower maintenance option. You might consider Epimediumx perralchicum'Frohnleiten' Great Plant Picks: Unbeatable Plants for the Maritime Northwest Garden or Epimediumx versicolor'Sulphureum' Great Plant Picks: Unbeatable Plants for the Maritime Northwest Garden both are tough evergreen ground covers with beautiful yellow flowers. If you must plant turf, Sargent Cherry is expected to be among the species vulnerable to climactic changes projected for our region. You might consider substituting a hornbeam like Carpinus betulus 'Fastigiata' Great Plant Picks: Unbeatable Plants for the Maritime Northwest Garden or 'Frans Fontaine' , Great Plant Picks: Unbeatable Plants for the Maritime Northwest Garden . Both are handsome trees suitable as a street tree and expected to be resilient and adaptable. Another good choice would be Nyssa sylvatica'Wildfire' Great Plant Picks: Unbeatable Plants for the Maritime Northwest Garden Conifers Substitute Calocedrus decurrens (Incense Cedar) for Douglas Fir. This beautiful conifer is suitable for urban landscapes and can tolerate a wide variety of conditions. Great Plant Picks: Unbeatable Plants for the Maritime Northwest Garden Substitute Juniperus chinensis'Kaizuka' (or the 'Blue Point'juniper already spec'd on this project) for Mountain Hemlock. Mountain hemlocks often fail to thrive at lower elevations in our region. Great Plant Picks: Unbeatable Plants for the Maritime Northwest Garden For the mountain hemlocks located near building entrances, you might consider substituting Mahoniax intermedia 'Charity' or 'Winter Sun', which have the advantage of fragrant yellow flowers in winter. Great Plant Picks: Unbeatable Plants for the Maritime Northwest Garden Great Plant Picks: Unbeatable Plants for the Maritime Northwest Garden Note: Avoid interplanting with Malus, Crataegus, Pyrus and Amelanchier, with Calocedrus and Juniperus as they are alternate hosts to rusts that infect these genera. Two pines on the plan may not be the best choices long term. For Pinus nigra 'Compacta', you might consider substituting Abies pinsapo, an adaptable species that is a Great Plant Pick and RHS Award of Garden Merit winner. It's cultivar'Clarke' is slower growing and may be the best option for the space. Great Plant Picks: Unbeatable Plants for the Maritime Northwest Garden In place of Pinus mugo, you might try Pinus contorta'Spaan's Dwarf, Pinus contorta 'Spaan's Dwarf' I Landscape Plants I Oregon State University or choose a broadleaf evergreen shrub like Berberis x stenopylla 'Gracilis Nana' which has the advantage of yellow flowers in spring and zero maintenance. Berberis x stenophylla'Nana' I Landscape Plants I Oregon State Universitv Deciduous Trees Due to rust issues noted above and projected low resilience forAmelanchier, substitute Chionanthus retusus (Chinese Fringe Tree). Great Plant Picks: Unbeatable Plants for the Maritime Northwest Garden For the same reasons, substitute Lagerstroemia x'Natchez' for Malus tschonoskii Lagerstroemia x fauriei 'Natchez' - Xera Plants
