Neverendingly, I try to convince friends to grow jack-in-the-Pulipts, or Arisaema, in all their splendid variety. The tug of hesitation might be spurred by the pricey tags on said fabulous 'Jacks'. In the best catalogues for this sort of thing, http://www.plantdelights.com/ and http://www.asiaticnursery.com/ one little plant is usually $20 or more. Then one gets a tiny tuber that is usually not even visible in the little pot, so you just have to pray and mark the spot well with your quintessential plant markers. But I have found a source for an exceptional Arisaema consanguinem at such a fabulous price that I ordered three and they all 'bloomed'. Dare I share this valuable source? http://www.bigdipperfarm.com/ in California is a cornucopia of many great plants. This one is all sold out now, but get on the waiting list. The otherworldly ends are divinely called drip tips. Fabulous.
