Ashitaba, Reiso Red (Angelica keiskei koidzumi), packet of 10 seeds, organic

(3 customer reviews)


Family:  Carrot (Apiaceae)

Hardy to Zone 7 to 12.

(HACHIJO-SOU, Tomorrow’s Leaf, Red ashitaba)  Rare, red-stemmed cultivar originally from Japan, grown here at our oganic greenhouses in Williams, Oregon.  Limited harvest of seed from the red cultivar, your early order is advised.   Reiso is Japanese for “mysterious or mystical plant.” The red stem type is purportedly stronger in medicinal activity than the standard green-stemmed type.  Perennial, high chlorophyll plant with yellow sap, unique among Angelicas due to its edibility and the presence of both B 12 and the flavonoids known as “chalcones.”  Mature size is about 4 feet wide and flowering to about 5 feet tall.  The plant requires warm temperatures for optimal growth–75 to 85 degrees F.  They need at least 6 hours sunlight daily to thrive!  It is often best to greenhouse them, although coastal climates (such as San Francisco area) seem to work pretty well for outdoor cultivation, and zone 8 growers may find that these plants do fine in regular open garden conditions.  Plant prefers potted culture in an unheated greenhouse or may be grown outdoors in maritime regions.

How to start the seeds:  Soak seeds overnight in cool, non-chlorinated water and then refrigerate the seeds (approximately 40 degrees F) in moist medium for 30 days.  The moist medium could be moist sand, moist potting soil, moist coir or moist peat.  Note that our recommendation is moist, not sodden, and that we are recommending refrigeration not freezing.  After this pretreatment, plant the (still moist) seeds.  Sow on surface, barely cover with soil and press in firmly and keep evenly moist until germination.  When we say to barely cover with soil, we truly do mean to use a very thin layer.  Actually, the best orientation is to half-cover the seed with soil and tamp firmly, leaving a portion of the seed showing to the light.  Use a greenhouse, shadehouse or grow lights.  Germination occurs 15 days after sowing.   Seedlings are slow-growing and will require about 60 days to transplant.  Once past the seedling stage, the plant is fast growing.
