The quiet colour in the lobelia range
Wild Lobelia erinus is blue to violet, so white forms are a result of selection. Even so, they are among the best known, often with a faint pale blue or yellow marking in the throat. Each flower is small, but dozens open at once, and the effect is a soft white froth along the edge of a pot.
What to plant it with
White lobelia is useful as a filler in mixed containers:
- under tall red or purple pelargoniums, where it trails over the rim;
- beside dark-leaved plants such as coleus, for contrast;
- along a path edge with alyssum or violas in cooler months.
Seasons that suit it
The plant likes mild weather. In Melbourne, Hobart and the cool highlands it can run from spring into the first part of summer. In Sydney, Perth and Adelaide, planting in autumn gives flowers through winter and spring. In subtropical Brisbane or Darwin, hot humid summers usually finish it, so use it in the dry season only.
Everyday care for white lobelia
Water regularly, since small pots dry quickly in a hot wind. Position it where it gets morning sun and some afternoon shade. After the first big flush, cut it back by roughly half and feed; it frequently returns with a fresh round of flowers.
Keeping pets safe around white lobelia
In the language of flowers, white generally suggests purity and simplicity. Lobeline in the related Lobelia cardinalis is toxic to pets according to the ASPCA, so keep edging plants out of reach of chewing animals.
