The birth flower of July, larkspur (delphinium consolida) is a staple in any cottage garden, both on its own and planted with other flowers, and will readily self-seed, coming back year after year.
Larkspur are upright annuals with deeply pinnately or palmate leaves, and racemes or panicles of small, spurred, delphinium-like flowers in summer. The roots grow into the soil up to a depth of 50 centimetres (20 in), so the plant can survive long periods of drought.
The Brisbane variety was bred specifically as a cut flower and has strong stems carry long spires of fully double flowers. Upward growing side branches mean less tangling when flowers are being picked.

STARTING YOUR SEEDS
Larkspur are an easy-to-grow and unfussy plant, but there is still one important factor to take into consideration: these seeds must have a cold period in order to germinate. In most places, this means that you should sow the seeds directly in the ground in the fall.
If it does regularly stay colder than 18 C (64 F) during the winter, they will not grow!
In warmer climates, the best way to ensure a cold spell is to pop them in the fridge in an airtight plastic bag for two weeks before planting. Once planted, the seeds should germinate within three weeks.
Start with well-draining soil. If planting in pots, make sure there are adequate drainage holes at the bottom. You can sow them directly in the ground since the roots do not like being transplanted.
Space the seeds around 15-20 cm (6-8 inches) apart then top with a very light layer of soil. They really should never be more than half a centimeter deep.
Water deeply to encourage root development, but be sure the roots do not stand in water as they will rot.
Sow indoors in spring. Sow under glass autumn-winter. Indoors, surface sow onto moist, well-drained seed compost. Just cover seed with a sprinkling of vermiculite. Germination may occur in 2-4 weeks.
Seed can be sown autumn-winter, surface sow, just cover with vermiculite, place somewhere dry and frost free, a garage or greenhouse is ideal.
