Hymenidium davidii W/O-0082
15 seeds per packet.
The seeds we offer have been harvested from plants grown by us from seed collected by August Wu and Bjørnar Olsen in Jiajinshan, Xiaojin, Sichuan, China.
This has to be the most spectacular member of the Apiaceae family (Umbellifer) we have ever grown! Hymenidium davidii (formerly Pleurospermum franchetianum) is native to the alpine grasslands and rivers banks of Gansu, Hubei, Ningxia, Qinghai, Shaanxi and Sichuan, China. It produces large, umbels of white flowers with dark purple/black anthers and amazing, white, marginal bracts followed by inwardly curving, dark brown/black seed heads, held on erect stems from June to August. When we first showed this breathtaking plant flowering with us for the first time on Instagram this year many people commented that it resembled a giant Astrantia. We cannot comment if this species is truly perennial or monocarpic just yet. Fantastic plant for bees and other insects. Height 70 cm. Moisture retentive soil in sun to part shade.
GROWING INSTRUCTIONS:
Sow upon receipt (best in autumn). Cover seed thinly, press in gently and keep top of compost from drying out. Keep pot outdoors or in cold frame over winter. Seeds germinate in spring.
Alternatively, if seeds can’t be sown in autumn use the following method: mix seeds with damp vermiculite and place inside a ziplock bag, keep bag somewhere warm for 3 weeks, then place in fridge (not freezer) for 8 weeks. Next spread mixture on top of a pot, thinly cover with compost or grit and keep warm at 15 to 20°C until germination, then move to somewhere cooler.
Carefully prick out seedlings when they have developed true leaves and are large enough to transplant to individual pots for growing on.
