Please donate to support our ‘Plants to Save the Planet’ Project. The Project is directed at enabling designers of ‘carbon farms’ and ‘food forests’: agroecosystems of perennial plants, to choose the most appropriate plants for their requirements and site conditions. We are working on a subset of plants in the PFAF database identified as having the most potential for inclusion in such designs. We are adding search terms and icons to those plants pages, and providing a range of search options aligned to categories of plants and crop yields, with Help facilities including videos. More >>>

Our new book Edible Shrubs is now available.

Edible Shrubs provides detailed information, attractively presented, on over 70 shrub species. They have been selected to provide a mix of different plant sizes and growing conditions. Most provide delicious and nutritious fruit, but many also have edible leaves, seeds, flowers, stems or roots, or they yield edible or useful oil.

Dye

The yellow dye obtained from the stigmas yields a yellow dye, it is a saffron substitute[177].

Cultivation details

Succeeds in most soils, conditions and positions[1]. Plants grow well in a peaty soil in a bulb frame and should succeed outdoors in a sandy peaty soil[90]. The subspecies C. serotinus austriacus can be naturalized in grass or beneath deep rooting trees on light well-drained soils[200]. Plants tend to move considerably from their original planting place because of their means of vegetative reproduction, it is therefore wise not to grow different species in close proximity[1]. Any planting out is best done in late spring or early summer[245]. Mice are very fond of the corms of this species[1]. Plants take 3 - 4 years to flower from seed[200]. The flowers are only open during the day time, closing at night[245].

Propagation

Seed - best sown as soon as it is ripe in a light sandy soil in pots in a cold frame[1]. The seed can also be sown in a cold frame in early spring[1]. Sow thinly because the seed usually germinates freely[1], within 1 - 6 months at 18°c[164]. Unless the seed has been sown too thickly, do not transplant the seedlings in their first year of growth, but give them regular liquid feeds to make sure they do not become deficient. Divide the small bulbs once the plants have died down, planting 2 - 3 bulbs per 8cm pot. Grow them on for another 2 years in a greenhouse or frame and plant them out into their permanent positions when dormant in late summer[K]. Plants take 3 - 4 years to flower from seed[200]. Division f the clumps after the leaves die down in spring[1, 200]. The bulbs can be planted out direct into their permanent positions.
