Description

Mimulus Medius F1 Pastel Crimson is a compact monkey flower from the Medius F1 series, selected for its large flowers and generous flowering in partial shade. Its soft carmine-red corollas adorn pots and cool borders from late spring until the first frosts. This variety thrives in cool, moist conditions: it is particularly well-suited to slightly shaded spots in the garden and sheltered containers.

Mimulus Medius F1 Pastel Crimson belongs to the Phrymaceae family and the horticultural group of Mimulus × hybridus (syn. Erythranthe × hybrida). These hybrid monkey flowers descend from South American species found on riverbanks and in damp meadows. In our temperate climates, 'Pastel Crimson' is grown as an annual as it does not tolerate cold.
This cultivar is part of the Medius F1 series, selected by the Czech seed company Černý Seed for its low, well-branched habit, rapid flowering, and large flowers. 'Pastel Crimson' stands out with its very soft carmine-red colour, brightened by a golden-yellow throat, highly uniform from one plant to another. Within a few weeks, the plant forms a rounded, dense clump, 20 to 25cm tall and wide. The green, supple stems branch from the base and bear opposite, bright green foliage. The leaves are oval and sometimes slightly toothed, fairly tender. The flowers appear continuously at the tips of the stems or short shoots. Each 5 to 5.5cm wide corolla, consists of a tube ending in two lips: one upper lip slightly upright, the other broader and trailing. Flowering extends from June to September, or even until the first frosts if the soil remains damp. The nectar-rich flowers attract bees and other insects.

Plant Mimulus Medius F1 Pastel Crimson at the front of borders that are always slightly damp, at the edge of ponds, in shaded rockeries, or in large pots on a balcony sheltered from scorching sun. It thrives in containers in partial shade, alongside dark or bluish foliage. It can be paired with the purple cushions of Heuchera ‘Forever Purple’, the small blue-grey clumps of Hosta ‘Blue Mouse Ears’ or the orange cascades of Begonia boliviensis ‘Summerwings Apricot’. To vary colour effects, other monkey flowers can also be planted nearby, such as Mimulus x hybridus Mystic Mixed F1 Hybrid.

Planting and care

Sow Mimulus Medius F1 Pastel Crimson in seed trays from March to May on the surface of good-quality seed compost. Keep the substrate moist without overwatering at room temperature between 20 and 30°C. Do not exclude light, as it plays a part in the germination process. You will need to wait 10 to 21 days before the young shoots appear. 
Gradually acclimatise your seedlings to cooler temperatures. Once they are strong enough to handle and all risk of frost has passed, transplant them outdoors into a humus-bearing, well-worked soil, taking care to space each young plant 20-25cm apart. Removing faded flowers encourages repeat flowering.
