Lupin 'My Castle'

Lupins may need staking.
Remove the faded flower spikes before the seeds have chance to develop, as this will conserve the plants energy and encourage further flowers.

Try to plant in a location that enjoys full sun and remember to water moderately. My Castle is generally regarded as a hardy plant, so this plant will grow or become dormant during the winter.

Lupin seeds can be sown in spring summer or autumn and generally flower best in the second season, but more modern seeds can flower in the same year.
Soak the seeds for 24 hours in water before sowing in pots or modules, fresh seeds germinate more easily.

Sow at a depth of approx. 0.2 inches (0.5 cm) and aim for a distance of at least 0.78 inches (2.0 cm) between Lupin plants. For optimal germination, soil temperature should be a minimum of 10°C / 50°F.

Pot up individually into 7cm pots and continue in sheltered conditions until large enough to plant out into the border or flowering position.
Lupins require an open sunny spot in well drained slightly acidic soil of even moisture

My Castle is hardy, so ensure you wait until all danger of frost has passed in your area before considering planting outside.

Lupin spires make good cut flowers, pick as the buds open about one third of the way up the stem

This variety tends to mature and be ready for harvest in mid summer.
