Consolida ajacis

'Consolida' is a cool weather annual that is easily grown from seed. in loose, moderately rich, consistently moist, well-drained soils in full sun. Tolerates some light afternoon shade in hot summer climates. Avoid wet soils.


Flowering

From Mid Summer TO Mid Autumn

Consolida flower approximately 14-16 weeks from Spring sowing, and blooms from mid Summer to mid Autumn

 

Planting

From Mid Spring TO Late Spring

Plant out to a sunny position in well-draining soil. As the plants grow, they will need staking

 

Propagating by seed in Spring

From Early Spring TO Late Spring

Germination is better if the seeds are chilled by placing them in the freezer for one week prior to sowing. Sow inside from early Spring to late Spring in compost with the seed lightly covered with vermiculite; or direct sow in late Spring

 

Propagating by seed in Autumn

From Late Summer TO Early Autumn

Sow seed in situ in late Summer or early Autumn

 

Planting young plants

From Early Spring TO Mid Spring

Delphiniums are very difficult to grow from seed. Buy as a potted plant at the nursery. Plant in the spring. Prepare the soil, mixing in 2 to 4 inches of compost. Dig a hole twice the diameter of the plant’s container. When planting, ensure that the top of the root ball is level with the soil. Insert supports no later than midspring or when the plants reach 12 inches high. Stake the low-growing perennials with twiggy, brushwood support. The taller, large-flowered delphiniums need sturdy stakes.

 

Flowering Season

From Early Summer TO Late Summer

Delphiniums are perennials grown for their showy spikes of colorful summer flowers in gorgeous shades.

 

Propagating by cuttings

From Early Spring TO Mid Spring

Take Basal cuttings when young emerging shoots have two or three pairs of leaves, take a thin portion of parent tuber or root material with the shoot
