Terry:
Stan has the green cultivar of Australian Finger Lime, you could purchase a one gallon size from him. If your question is how easy are they to propagate as a cutting?....I'd rate them pretty easy. I prefer a 6"-8" stem length, strip the bottom leaflets up an inch or so. I root in perlite, under mist and over a heat cable but you can duplicate bottom heat in many areas of the home. A plastic bag over the cutting preserves moisture but should be sprayed with a light mist daily. I do use a hormore rooting solution. I'd expect roots in 4-6 weeks. Feel free to email if you have other questions.
