water
info		 Water this plant regularly, when the top inch or so of soil feels dry. If you establish this pattern over several years, then you can cut back to watering every week or two in dry weather. Use drippers, emitters, or a slow stream of water so that it doesn’t run off; allow the water to trickle all the way down through the deepest layers of soil. In a pot slowly water the entire surface until water comes out of the bottom of your pot.

Growing Notes

Very fast growing and also relatively short lived.
Loves coastal climates where it blooms sporadically through the seasons.
Adaptable to various soils, except for heavy clay soils.
The sweet pea shrub looks best with sheering to keep it dense, but also appears a bit twiggy and chopped after a pruning. Luckily this tough plant rebounds quickly. It’s best not to try and force this plant to be significantly smaller than it’s natural size, as it rebounds so quickly after pruning.

Special Interest

Likely a hybrid of Polygala oppositifolia and Polygala myrtifolia.
