Fortunately , projects like the University of California Landscape Plant Irrigation Trials are giving the gardening and landscaping industry data they can use to describe works that can hold out minimal irrigation over a sustained period .
In the UC Landscape Plant Irrigation Trials , UC Davis horticulturists evaluate landscape plants with the potential to be unspoiled performing artist in low - water system utilization landscapes . Cultivars are supply by growers and breeder who want to value their varieties for low - water use in hot California gardens .
Over the course of the trials , plants are measure for overall appearance , flowering time and duration , and pest or disease problems on their lowest irrigation treatment . Those that perform best take in a Blue Ribbon denomination .
To earn the Blue Ribbon , the plant has to resist out in the garden , look good most of the twelvemonth , and require minimal pruning . In the latest test , three of the seven plants that maintained these high standards of esthetic quality were Proven Winners ColorChoice varieties . comment about these variety take from the 2018 - 2020 Trial Results composition admit :
Buddleia x ' SMNBDBT ' Pugster Blue“Pugster Blue performed beautifully in the Davis high temperature and received gamey marks for overall appearance throughout the season on all treatments , earning it our Blue Ribbon accolade for very good performance on low water . ”
Hypericum kalmianum ' Deppe ' Sunny Boulevard“Sunny Boulevard forms a tidy little mounded deciduous shrub with small , shiny greenish shoulder strap - shaped leave that come forth in early May . In Davis , this collapse into bloom with lustrous yellow flowers that continued through July and were very attractive to pollinator . ”

The overall appearance and leaf health were systematically very good in Davis , though the occasional industrial plant modernise a non - undifferentiated build which would be easily corrected with small pruning . ”
A great showing for Proven Winners ColorChoice cultivars as Spring Meadow Nursery continue to measure these type of water - saucy shrubs for inclusion body in its catalogue .
