Why the All-Stars ? Increasing urban growth plus decreasing water supplies Save time and money Support wildlife-the 4 Bs Less water, care, chemicals Bees, butterflies, birds, beneficial insects Our unique “Mediterranean” climate What makes an All-Star? Every All-Star plant must: Be attractive for most of the year Be tested in the UCD Arboretum All-Stars were also selected for: Drought tolerance Attracting beneficial wildlife (4 Bs) Low maintenance Year-round interest Irrigation Trials: levels of water 4 Trial Gardens in 11 Sunset hardiness zones Perennials vs. Annuals Annuals: •1 year/ 1 season – then replant Perennials: •Multiple years •Flowers 1 season All-Stars are perennials Perennials vs. Annuals Annuals: •1 year/ 1 season – then replant Perennials: •Multiple years •Flowers 1 season All-Stars are perennials Garden Building Blocks TREES – anchors SHRUBS – structure LOW FLOWERS - accessories Perennials-shade Serpentine Columbine Aquilegia eximia Perennials-shade Rosy Coral Bells Heuchera rosada (and others) Perennials-shade Alum root Heuchera maxima Perennials-shade Lenten rose Helleborus x hybridus •low evergreen •Blooms in winter to 1 ft.

Break soil chunks up thoroughly ii.If too deep, backfill 3.Score sides of hole 1.Check plant roots and loosen ball 2.Place plant on firmed soil in center – spread roots 3.Plant ½ in. above ground level 4.Backfill with soil, tamping gently 5.Build a berm with excess soil 2” is okay – 3” is better • Conserves moisture • Cools soil • Suppresses weeds • Slowly adds OM to soil No need to buy if you have a truck Free from SMUD yard, tree services • Trees- keep 6” from trunk • Shrubs- keep 3” from trunk • Perennials- closer REPLACE WITH TOP DRESSING EVERY 2 YEARS No need to buy if you have a truck Free from SMUD yard, tree services 1.Regular water the first year i. Every 2-3 days in the heat ii. Once a week as it cools and rains iii.CHECK BY FEEL 2.For larger shrubs and trees -2 years 3.After establishment: i. Knock down berm ii. 1x /week or 2x/month watering iii. NO WINTER WATER 1.Prune off spent flowers 2.Prune to shape 3.Cut back most grasses in late winter 1.Trees - NO 2.Whole beds before planting - YES 3.Individual plants – probably not 1.Add at least 4-6” or more of composted OM and till in to twice the depth 2.Basic soil sulfur will help lower soil pH SLOWLY 3.Use natural bone meal or blood meal for Nitrogen SUN Combo: Cool colors Shade/Semi-shade Combo: Cool colors SUN Combo: Red, white and blue: SUN Combo: Hot colors SUN Combo: Primary colors A searchable plant guide http://arboretum.ucdavis.edu/arboretum_all_stars.aspx Acknowledgments: •Ellen Zagory, UC Davis Arboretum •Native Sons, High Ranch, McCall’s Nurseries •California Center for Urban Horticulture •Capitol Nursery •UC Davis Arboretum
