Top cut flower for hot summers. Water at soil level — wet foliage causes powdery mildew. Deadhead to extend bloom. Attracts butterflies and hummingbirds.
Ipomoea purpurea
Thrives in the same full sun, moderate water conditions as Zinnia
Start Zinnia indoors about 4 weeks before your last frost, keeping seeds in warm soil (around 20–25 °C). Seeds usually come up in around 7 days. Move seedlings out once the danger of frost has passed, in full sun, spaced about 30 cm apart. Expect the first blooms in roughly 60 days.
Zinnia seed rarely stays viable beyond 4 years — track what's still worth sowing.
Water: Medium · Height: 90 cm · Soil: Well-draining, average to fertile — tolerates heat
Braconidae, Ichneumonidae and relatives
Pinhead-sized, stingless, and lethal to aphids and caterpillars from the inside.
These three thrive alongside Zinnia — and alongside each other.
