When to plant Foxglove in Arid Australia

Arid zone — applies to Alice Springs, Mildura, Broken Hill, Kalgoorlie, Port Augusta and similar areas. Growing elsewhere? Temperate · Cool · Subtropical · Tropical.

Sow foxgloves direct from March to July across the cool inland autumn and winter, giving these hardy biennials the mild season they need to establish before summer. Barely cover the dust-fine seed at about 3 mm, since light aids germination, which takes 14–35 days. Thin seedlings to 30–40 cm apart in rows 30–45 cm wide. As biennials they form a leafy rosette first and send up their tall flower spires at around 120–130 days from sowing. In Mildura and Port Augusta they need a cool, sheltered, moisture-retentive spot, as the open desert summer is far harsher than their woodland origins prefer.

Growing notes

Foxgloves are cool-climate woodland plants, so the arid zone is a stretch and the failures reflect that. Heat and drought are the killers. In open inland sun the rosettes scorch and the tall spires can cook before the flowers finish, so plant in the coolest, most sheltered position you have, with afternoon shade and deep organic mulch to keep the root zone cool and damp.

The seed is another common trip-up. It is extremely fine and needs light, so sow it barely covered at 3 mm and keep the surface consistently moist through the long 14–35 day germination. Sowing too deep or letting the surface dry in the low desert humidity is the usual reason seed never appears.

Water matters through the whole cycle. These plants want steady soil moisture and sulk when the bed swings dry, so irrigate consistently and enrich the soil with compost to hold water between soaks. Grow them as a two-season project: the rosette overwinters and the spire follows the next warm period. A note of caution, all parts are highly toxic if eaten, so keep them away from vegetable beds and children. Let a spire or two set seed and you may get self-sown replacements.

Common questions

Can foxgloves grow in a hot dry climate?

They can, but only in the coolest, most sheltered corner with afternoon shade and generous mulch. Sow through autumn and winter so the plants establish before the harsh inland summer, which otherwise scorches them.

Why won't my foxglove seeds come up?

The seed is extremely fine and needs light, so it must be sown barely covered at about 3 mm. Keep the surface consistently moist, as it can take 14–35 days to germinate and dries out easily in low humidity.

Do foxgloves flower in their first year?

Usually not. As biennials they form a leafy rosette first and send up flower spires the following season, reaching flowering maturity at around 120–130 days once conditions warm.

Are foxgloves poisonous?

Yes, every part of the plant is highly toxic if eaten. Site them well away from vegetable beds and where children play, and wash your hands after handling them.
