    ‘Cutie’ of the genus…smallish YELLOW spathe flowers on this Cobra Lily from Asia appear in June>July at the same time as the two compound leaves with up to 11 leaflets that radiate around the stem like fans (pretty!); much variance in stem height, 6”-30”, increasing with age. Takes more sun than others, morning sun to light shade, typical for genus - well drained, rich, moist soil (avoid winter wet). Stalks of red berries late summer will reseed as plants mature and along with offsets, create a slowly expanding patch of exotic cuteness.

    This little charmer has tiny (1/2”) rich yellow flowers in late spring. The seedpods flower all summer and will make a nice patch.

    This unique cobra lily has bright yellow spathes. It grows to about one foot tall usually with two dissected leaves. Also unusual about this species is its distribution: while almost all species occur in Asia (with two species in eastern North America), A. flavum is found in Asia, the Middle East and North Africa -- quite the fascinating little traveller. Grows in drier habitats than your usual arisaemas so try it in dry shade!

    Himalayan species with deeply divided leaves and a bright yellow spathe and purple spadix, these are easy and more or less hardy, small tubers going on third year (its naturally a small species) but these should flower this year. ZONE 6

    According to literature only growing 8-18", it did start blooming at 8" tall, rather "cute" looking. 4 years later it was 30" tall and the otherwise small flowers were quite substantial. Did I mention the leaves? Gorgeous clean-lush-green composed of 5-11 leaflets, becoming bigger by the year as well. Easy in a well drained soil, tolerates more sun than others. These are extra large, 3-4 year old corms.

    I really like this Arisaema because, well, it bears a bright to mid-yellow “flower” as opposed to the much more common green or brown. It’s also adaptable, vigorous & easy to grow & blooms in its first year. Native to China, Arisaema flavum grows to 6”-13” tall with attractive deeply lobed palmate leaves. In late Spring to early Summer, up pop the “flowers” - actually modified leaves (known as spathes) which form a hood over the spadex (flowering part). These are followed by attractive scarlet berries. Grow Arisaemas in rich, well-drained soil in light shade. This one is an easy pot subject but keep moist as they don’t like to dry out. Will go dormant in mid-Summer-Fall here in coastal California. Mid Summer-Spring in colder areas. Tuberous roots.
