About this plant
This beautiful plant produces conical, yellow flowers which are extremely large in proportion to the plant's size and have a fragile appearance, akin to poppies in their texture. The clear lemon-yellow of the blooms is enlivened by a red calyx. They hold their faces up charmingly to the sun and have a slight but sweet perfume. The green leaves are long and shiny.

Spring
Spring-Autumn · Outdoors
Water in dry periods
Established plants in the ground can cope with 7-10 days of dryness, and shrubs often manage 2 to 3 weeks. Water one section of the garden thoroughly each day rather than a little everywhere. Check plants in pots more often, especially in hot weather.
Spring - early-mid · Planting
Divide when too large
The plant can be divided if it becomes too large or another plant is required. This may involve physically dividing the clump in two, removing offsets or small bulbs or dividing rhizomes. The new plants can be grown in pots or planted in the ground.
