When to plant Stock, Virginian in Temperate Australia
Temperate zone — applies to Sydney, Melbourne, Adelaide, Perth, Newcastle and similar areas. Growing elsewhere? Cool · Subtropical · Tropical · Arid.
Sow Virginian stock direct where it is to flower in February, March, April, August, September, October or November, scattering seed thinly and covering it with just 3 mm of fine soil. It germinates fast for a flower, in 7–14 days, and races to bloom in only 60–80 days, making it one of the quickest scented annuals you can grow. Thin seedlings to 15–20 cm apart in rows about 25 cm apart. This easygoing hardy annual is ideal for edging paths and filling gaps in temperate gardens around Newcastle and Adelaide, where its evening perfume carries on mild nights.

Growing notes
Virginian stock is about as low-fuss as flowers get, which makes it a good choice for beginners and for quick colour between slower plantings. Because it matures in 60–80 days, you can sow across both the autumn and late-winter-to-spring windows listed and keep a rolling display going through the milder parts of the temperate year in cities like Perth and Sydney.
Sow direct rather than transplanting; the seedlings are small and resent root disturbance. Rake the bed to a fine tilth, broadcast thinly, and cover with just 3 mm of soil. The most common failure is patchy, leggy growth from sowing too thickly and never thinning. Crowded plants stretch, flop, and flower briefly, so thin honestly to 15–20 cm even though it feels ruthless.
Give it full sun to light shade and ordinary soil; overly rich beds push leaf over flower. Keep the surface just moist during germination, then water only when the top few centimetres dry out. In a warm temperate spring the whole cycle can be over quickly, so successive small sowings a few weeks apart give a longer season than one big planting. Let a few plants set seed and they will often self-sow into next year.

Common questions
- How long does Virginian stock take to flower?
- Only 60–80 days from sowing, which is very fast for a scented annual. Sowing direct in the recommended windows means you can enjoy blooms within a couple of months and repeat-sow for a longer season.
- Can I sow Virginian stock straight into the garden?
- Yes, and you should. It dislikes being transplanted, so scatter seed direct where it is to flower, cover with 3 mm of fine soil, and thin the seedlings to 15–20 cm apart once they are up.
- Why is my Virginian stock leggy and thin?
- Almost always overcrowding. Sown too thickly and left unthinned, the plants stretch for light and flower poorly. Thin to 15–20 cm spacing and grow in full sun for compact, well-branched plants.
- When can I sow Virginian stock in Adelaide?
- Use the autumn window of February to April or the late-winter-to-spring run of August to November. Adelaide's mild temperate climate suits both, and staggered sowings keep the perfume going for months.
