| i wish i had a buck for every time i have typed this... NOTHING EVER STOPS GROWING .... especially conifers ... MOST height and width estimates are at ten years.... and every year thereafter.. they will continue to grow at the annual growth rate ... so if something grows 2 feet per year... it will outgrow your spot in about 5 years ... if it grows 3 inches per year... it will take about 20 years ... at the link.. is a great tutorial about conifers.. describing mini/dwarf/large size categories for conifers... there you will also find a database.. where you can plug in the names of suggested picea pungens ... you should look up donna's rainbow ... grows about 3 inches per year in my garden .... there are also some blue firs that grow pretty slow, such as Abies lasiocarpa [var. arizonica] 'Compacta' about 4 inches annual for me ... there are also some blue concolors with slow growth ... dont know where you are [zone].. so no comment about whether either are appropriate for your garden ... why pungens???? or are you looking for blue??? good luck ken |
