When to plant Stock, Virginian in Cool Australia

Cool zone — applies to Hobart, Canberra, Ballarat, Orange, Armidale and similar areas. Growing elsewhere? Temperate · Subtropical · Tropical · Arid.

Sow Virginian stock direct where it is to flower in February, March, September, October or November, scattering seed thinly over prepared soil. Germination is fast at 7–14 days, and the plants race to bloom in just 60–80 days, making this one of the quickest scented flowers for a cool garden. Sow only 3 mm deep and barely cover the fine seed. Thin or space seedlings 15–20 cm apart with rows about 25 cm across. Fully hardy and undemanding, Virginian stock suits an edging or gap-filling sowing in cool towns like Ballarat, Orange and Hobart, giving evening fragrance within a couple of months of sowing.

Growing notes

Virginian stock is a true sow-and-forget annual, and its speed is its charm. In cool districts you get two clear windows: an early-autumn sowing in February and March that flowers before the first hard frosts, and a spring run from September to November that carries scent through the warmer months. Choose an open sunny bed and rake the surface to a fine tilth before broadcasting seed.

The usual failure here is sowing too deep or too thick. This fine seed needs light to germinate, so a 3 mm covering is plenty; bury it and it simply will not come up. Sown too densely, plants grow thin and weak and finish flowering quickly. Scatter sparingly and thin ruthlessly to 15–20 cm so each plant branches and blooms properly.

Because the whole cycle runs only 60–80 days, succession sowing every three or four weeks keeps colour and evening fragrance going right through the frost-free stretch. In frost-prone spots like Canberra and Armidale, avoid sowing into midwinter; a hard frost will cut down young seedlings even though established plants are hardy. Water gently until germination, then Virginian stock largely looks after itself in average soil.

Common questions

how long does Virginian stock take to flower

Very fast, usually 60–80 days from sowing to bloom. That speed makes it ideal for filling gaps and edging beds in a hurry. Succession sowing every few weeks keeps the flowers and evening scent coming.

can you sow Virginian stock direct in cool climates

Yes, it is best sown direct where it is to flower rather than transplanted. In cool zones sow in February and March, then again from September to November. Just scatter the fine seed thinly and barely cover it.

why won't my Virginian stock seed germinate

The most common cause is sowing too deep. This fine seed needs light and should sit under just 3 mm of soil. Keep the surface damp until the seedlings appear in 7–14 days.

is Virginian stock frost hardy in Orange

Established plants are hardy and cope well in cool towns like Orange, but young seedlings can be killed by a hard frost. Avoid midwinter sowings and stick to the autumn and spring windows. That way plants flower in milder weather.
