Ranunculaceae: A climbing perennial species originally collected of from the Western Heights overlooking Kunming, Yunnan. Where it twined up scrub and over large rocks to 3m tall, bearing large three-parted palmate leaves. With generous axillary inflorescences of long stemmed deep blue tinged purple flowers 5cm long, primarily composed of a large upper helmet-shaped petal. Coming into flower in late July.
A vigorous climber, best with its roots in the shade and grown into the sun, any good soil.
Cold germinator. The sowing must be kept warm (about +18 to +22°C) [about 64 to 72°F] and moist for the first 2–4 weeks. After this period the sowing must be kept at a cold temperature (between –4 and +4°C) [between 25 and 39°F] for another 4–6 weeks. Colder temperatures of –5°C [23°F] are only advantageous for most species of the Ranunculus family.
Most species of the Ranunculus-family need lower temperatures during the cooling-period – about –5°C [23°F]. In other respects. The reason is probably the freezing point of these seeds, which is at –7°C [19°F], while most other seeds freeze at –5°C.
