With Agastache 'Morello', the flowerbed welcomes a plant whose flowers display pink tones. The foliage presents shades of green, to be highlighted among different textures. The usual flowering period is June-September. Its size of 70 cm by 55 cm reserves it a place in the middle of the flowerbed and for group planting, without forgetting the space for neighboring plants.
The success of Agastache 'Morello' begins with its location: full sun, in suitable soil (draining, rather light; avoid water pockets around the collar). After planting Agastache 'Morello', water enough to thoroughly moisten the root ball. Once established, let the surface dry between waterings and prioritize drainage, especially during thaws. A margin corresponding to its spread of 55 cm avoids having to move the clump in the first seasons. The indicated hardiness level is zone 5, to be evaluated according to your garden's conditions.
In an Agastache 'Morello' planting, wait to see spring regrowth before removing parts that have dried during winter. Winter drainage is crucial for this agastache; avoid depressions where water accumulates during thaws. For associations, consider border salvias, upright sedums, yarrows in varieties with similar needs. The flowering (June-September) and the spread of 55 cm will serve as benchmarks for distributing other plants around this plant.
