Brugmansia x candida

Updated: Nov 2, 2021


"Fabulous!" is not exclaiming enough about these showy flowers on a very large "perennial" plant. Usually when I think of perennials, all too often they are mounding and quaint (yes, I know there is a lot of variety out there, but work with me here). In reality, this perennial, as some will reference, is actually a tropical shrub with woody branching and herbaceous, fuzzy stems. In their native environment, they remain evergreen, but for us in the Bay Area, angel's trumpet will typically be semi-deciduous or deciduous...in essence acting as a perennial due to the Bay Area's varied winter temperatures. Horticulturally, we still classify B.x candida as a shrub.


Few shrubs present these wonderous, dangling trumpets that can make one feel as if they've fallen down Alice's rabbit hole. Cultivars offer white, yellow, or pink shades with single or double forms. Fragrant, too. If the garden site can meet B.x. candida's needs (it's quite specific about soil, moisture and exposure), then there are other things to consider.


For example, B. x candida does need a lot of attention, particularly when their overall form is developing. I have often seen them looking like small trees with all the blooms spread out at the top (see photo below), rather then graduating their structure to allow blooms all over. Attractive when in bloom, they still need extra attention to maintain a desirable tree form by selectively thinning stems. When not addressed, it might mean that the lower portion looks a little bare or ratty. One solution is to add complimentary, evergreen plants in the foreground. Angel's trumpets can have a rough time over the winter, too, so something evergreen will hide this plant when it is not looking its best.


We had one in Palo Alto on a side yard that received only midday sun and protection from winter frost by the adjacent fence. It still was severely damaged by frosts and was unattractive for a few months until it bloomed again. When the sun passed by, the heat would wilt the leaves. That was a long time ago; today's warmer climate helps to endure winters, but they will benefit from late afternoon sun protection. This species is also popular in coastal gardens, including San Francisco's intimate courtyards and gardens. Angel's trumpets do like their water, so be sure to place it in a complimentary moderate hydrozone.


cultivars of interest, as examples:


'Double White': multiple petals

'Frosty Pink': salmon pink flowers

'Variegata': green and white leaves
