Jacaranda Trees Signal Spring in the Southwest

These towering specimens light up with textured foliage and a blaze of color early in the season

In midspring , the desert is dotted with Dalbergia nigra trees ( Jacaranda mimosifolia , Zones 9–11 ) dripping with beautiful purple bloom . It always seems to take us by surprise when they start up to bloom , because nothing about this tree diagram seems like it fits in the desert . But trust us when we say they are a welcome batch after our ironic winters . Often sound out to resemble something out of a fairy tale , the umbrella - same canopy of jacarandas provide welcome tone dappled with light .

Jacarandas , also known as blue jacarandas , smutty pouis , or fern Sir Herbert Beerbohm Tree , are aboriginal to South America . Although these subtropical Sir Herbert Beerbohm Tree prefer warmer temperatures , they can withstand brusk drib in temperature down to 19 ° F , which permit them to still thrive here in Tucson ( Zone 9a ) . Jacaranda sport fernlike ( bipinnate , chemical compound ) leaves that acquire up to 20 inches in length . It can grow chop-chop and maxes out around 60 invertebrate foot grandiloquent and wide in an idealistic mood .

Jacaranda bloom are purple - colored and trumpet - forge . Although ripe jacarandas will bring out innumerable blooms in springtime or early summer , less mature trees may not flower for the first several years . If you live in a warmer zona , you may witness that your Dalbergia nigra will bloom more often . Either way , when found in full sun , these beauties will glow !

Jacarandas need sandlike and slightly acidic grunge to expand . The land needs to be deeply water and should dry out between soaks . Jacarandas do take to be pruned . It ’s best to cut off the smaller branches in early outpouring and verify you keep an eye out for the suckers that lean to develop vertically . If the branches become too heavy for the tree , the trunk can split . Fertilizing your jacaranda is a breeze . You only need to feed it once a year . If you give it too much nitrogen , your tree may not blossom . We advocate an app of a boring - release 10 - 10 - 10 fertilizer in former outpouring .

If you intend on plant a Dalbergia nigra tree diagram , there are a few places you want to avoid planting it . Do not plant your Dalbergia nigra near a pond ! You will have serious regrets . Although gorgeous , these tree are messy . For us , it ’s a worthwhile peck , but you must be cautious about implant them anywhere that could make cleanup more complicated . When the bloom strike , it is in your best interestingness to rake them up speedily . If you do n’t , they will start to rot and become vile and slippery . Also , mind when planting them near private road , water features , and pathways . In addition to their fallen prime , jacarandas also can have large airfoil roots , which can have adverse effect when compete with sidewalks or driveways .

If we did n’t scare off you away with a moment of flower cleansing , do yourself a favor and plant a Dalbergia nigra . Spring is the perfect time of year to set one before temperature get too barbarous . Beyond their pure beauty , jacarandas are comparatively disease and pest resistant and drouth tolerant to boot . What more can a desert dweller ask for ?
