It was only after opening the packet of seeds that I learned that it might take 5 years to see them bloom!!! Isn't that a bit of a joke on us, really???

Description

Paeonia 'Rockii Mixed' is a highly sought-after peony bearing large flowers composed of tissue paper petals, sometimes speckled with dark burgundy at their bases. It is incredibly generous and breathtakingly beautiful!

If peonies are so appreciated in our gardens, it is because of their opulence, longevity and robustness. Like the genus, the 'Rockii Mixed' variety displays a remarkable flowering from April to May, with flowers measuring up to 25 cm (10in) in diameter. White, yellow, salmon, light pink, and dark pink are offered here.

Originating from China and belonging to the Paeoniaceae family, the bush peony distinguishes itself from herbaceous peonies, which disappear in winter, by the woody nature of its stems. It is a hardy bush, at least down to -15°C (5°F), reaching a height of 1.5 metres (5 feet) at maturity.

The peony thrives in regions with distinct winters, as the cold stimulates the formation of its buds but dislikes spring frost that can damage them. Therefore, you should plant it in a sheltered spot, away from the wind, in full light or partial shade. Its generosity is also due to its appetite, at least during the first few years. We recommend regular additions of well-rotted compost and mulching around its base.

In the garden, the peony is ideal for a romantic flower bed alongside hardy geraniums, catmints, and roses. It is also charming and holds up well in bouquets.

Growing a peony from seed is not complicated, but it is slow and involves several stages. Your patience will be rewarded after 5 to 7 years with the appearance of the first flowers.

Planting and care

The germination of peony seeds can be slow and irregular, but your perseverance will be rewarded.

Upon receiving your Paeonia 'Rockii Mixed' seeds, place them in a plastic bag (such as a freezer) containing slightly damp sand or vermiculite. Seal the bag and place it in a location protected from direct sunlight, in a warm area around 21°C (69.8°F). For three months, the root system of your Peony will begin to develop. Once it reaches a length of 2.5 cm (1in), move your bags to a much cooler location, around 5°C (41°F), for 10 to 12 weeks.

Regularly monitor the development of your plants: as soon as the shoots appear, remove them from the bag and transfer them to pots. The growth should occur in a cool location until your plant is well established. Gradually acclimate it to the conditions of the garden.
