While jacarandas can be grown from seed, their flower colour varies more and they take longer to flower, but as seedlings often pop up around the base of trees, transplanting them is worth a try and doesn’t cost a cent. A thickness of no more than 50mm of mulch is recommended. Mulching around the roots with organic material (eg, compost, straw, bark, etc) will help to retain soil moisture in summer, but only apply the mulch over moist ground, not over dry ground, otherwise the mulch might prevent rain reaching the soil. Jacarandas like a sunny position and well-drained, fertile soil, plus regular summer watering. Jacarandas thrive in tropical and warm temperate climates, but they can be grown in cooler areas which get light frosts, but they usually don’t flower as well in these cooler zones, and they are also slower-growing, and smaller there. Jacarandas are readily available at nurseries in tropical and warm temperate zones. For the most reliable blue colour, and faster flowering, look for a modern grafted form. While the most common flower colour for jacarandas is the lovely purple-blue, there is a white-flowered form called ‘White Christmas’, but it is much harder to find this one at nurseries, and you’ll probably need to get it ordered in for you. However, planted in the right spot, a jacaranda is a magnificent shade tree. One big mistake some people make is to let a jacaranda overhang their swimming pool, where the fallen flowers rapidly clog up the pool’s filter. These trees can reach a height of around 10-15m, and a spread of the same size, so you need to be careful where you plant them, as they can extend a long way. In Australia however, Jacaranda foliage turns a lovely golden yellow colour in winter, and holds this colour for up to three months before bursting into bloom in late spring around November. They briefly drop their leaves at the end of the dry season, then leaf up again when the rains come. They are native to Brazil, where they are deciduous, not because of cold winters, but because of the monsoonal wet and dry seasons. Lots of people think jacarandas are natives, but they’re not. In winter, they produce striking, golden foliage. Of particular note, Stiles produced this heatmap of jacaranda trees in the city of Los Angeles.Australian streets are awash with the magnificent purple-blue blooms of jacarandas ( Jacaranda mimosifolia) in late spring and early summer.Īs well as being superb street trees, jacarandas look stunning on their own as a specimen tree in an open lawn, where their fallen flowers form a colourful carpet of blue. Times journalist Matt Stiles combed through open-data portals and filed public records requests to create a GitHub repository that contains info (including location and species) on 1.75 million trees in 50 L.A.-area cities. cities, it’s unfortunately not quite as easy. Simply plug “jacaranda” into the search field and you’ll see the locations for 1,031 jacaranda trees along streets and parks in the coastal city, including 20th Street north of Colorado Avenue on 11th, 12th and 31st Streets just south of the 10 and, most notably, at the eastern end of Ashland Avenue.Īs for the rest of the non-L.A. If you’re looking for trees outside of the City of Los Angeles, we’ll start with easily the slickest option of them all: the color-coded Santa Monica Public Tree Map. If you’re interested in trees that reside in city parks, just type “jacaranda” into the search bar of this other map. The two caveats: This only shows trees within the City of Los Angeles (so not Beverly Hills or West Hollywood, for instance) and only ones along the street, on public land. The Bureau of Street Services has created a map of every tree along the streets of the City of Los Angeles. The sheer volume of data makes that map borderline unusable, but we were able to create a modified version that shows only jacarandas (thousands upon thousands of them) that we’ve embedded above. (Just a heads up: This map may load slowly.)
