Growing from Seed
Sweetshrub is one of those generous plants that come along well from seed. A period of cold, moist stratification helps seed germinate evenly, after which it should be sown into a loose, well-drained mix. Full sun to light shade suits this hardy shrub well, and because flower fragrance genuinely varies between individual seedlings, growing several plants from seed offers fun possibility of finding a particularly fragrant specimen of your own. Sow evenly over the surface and cover lightly into a loose, well-drained seed compost, water in gently, and keep the sowing in full sun with steady moisture. Grow the youngsters on steadily in pots until well rooted, then move them to their final positions.
Our Take
Sweetshrub, Carolina Allspice settles in quickly once it finds its footing. Attention to moisture in the first weeks pays off; later, the plant is forgiving.
