I am very disappointed and have reported it: I was told that it was necessary to plant quickly (it was minus two) and water a lot: you need a magnifying glass to see the plant, but I was assured that the shoot was guaranteed (under what conditions)?

Description

Agastache 'Kudos Yellow' completes this excellent lineage of Kudos hybrid agastaches with an abundance of bright yellow flowers. It is a compact variety, which produces a multitude of opulent flower spikes loaded with flowers that attract bees. Its aromatic foliage perfectly perfumes the garden. The plant is naturally resistant to mildew. It easily survives our winters. Plant it in a sunny location in well-drained soil that is not too dry in summer.

 

Agastache 'Kudos Yellow' belongs to the Lamiaceae family, rich in plants producing essential oils. These substances protect them from both herbivorous animals and the sun's rays. This variety is no exception: its heart-shaped deciduous foliage releases a powerful minty and aniseed scent that delights the nostrils and repels pests!

Agastache 'Kudos Yellow' is part of the Kudos hybrid series. Plants in this group are characterised by a dense habit, as well as better resistance to cold and winter humidity than other agastaches. From June to October, it produces spikes in the shape of large "candles", high above the stems. The plant forms a compact clump, which can reach 45 to 50cm (18 to 20in) in height and about 45cm (18in) in diameter. Each pure yellow flower is nestled in a green calyx. These flowers are also edible in salads. The hardiness of this variety, although not exceptional (-15°C (5°F) in well-drained soil and sheltered location), is better than in other agastaches. Moreover, it is very nectar-rich and will be a true magnet for bees and other pollinators, especially in autumn when flowers become scarce in the garden. The deciduous foliage is absent in winter. Agastaches are perennials with a rather short lifespan, and usually fade away after 3 to 5 years. Divide the clump regularly.

 

Agastache 'Kudos Yellow' appreciates full sun or light shade (its stems droop in very shady situations). It will grow in any good garden soil that is not too chalky or too dry. Water potted plants regularly and they will reward you until autumn. It will look wonderful in a rocky bed or moist rockery with Erigeron karvinskianus, Sedum 'Angelina', Teucrium flavum, or even Delosperma 'Wheels of Wonder Orange'.

Planting and care

It dislikes consistently wet soils in winter, as they can harm its hardiness and eventually kill it. In heavy soil, pure sand can be used to plant the stump without adding any soil. It requires a sunny and sheltered position, protected from severe frosts. During very harsh winters, cover the stumps with straw or dead leaves to create a thick mulch. The soil should be fertile, loose, and moist but well-drained, especially during the flowering period. The plant can tolerate temporary periods of drought, although they can still affect its flowering.
