Growing these seeds will be an exercise in patience, but getting them from germination to bloom will certainly give you a sense of accomplishment! Cardiocrinum cordatum produces slow-growing bulbs that welcome spring with broad, glossy foliage. The leaves are heavily veined with red when they emerge, gradually turning solid green. Once the bulbs reach flowering size (around year 5 to 6, usually), they send up a stout stalk that generally reaches 3 feet tall in my garden, though the species apparently can get to 6 feet tall. (That may indicate that these seeds are actually C. cordatum var. glehnii, even though I did not receive the original seeds as that variety.)
The long-petaled, creamy white, lightly fragrant, summer blooms develop into large, chunky seedpods that are quite ornamental. That stalk dies, but it will leave offsets that will flower after a few more years. Partial shade is ideal; average to moist but well-drained soil. Perennial bulb. I am not sure about the proven hardiness range (some sources say up to Zone 3), but I know it is fully hardy for me in southeastern PA (Zones 6/7).
Collected in late October 2021. At least 20 seeds.
