Herman: I've been using vermiculite and perlite for a long time now, in various mixes, and especially for seedlings long before I started to grow Hepatica from seeds.What I found after using both in various ways, is that the vermiculite is great for seedlings mixes (short term potting), I also use it for keeping all the moist-packed seeds I offer. I has an excellent water holding capacity. The downside is that when used in mixes for longer term potting (3 years or more), the particles which are very soft when imbibed, will start to break up and therefore do not perform as well in assuring a good drainage as good as the perlite does.So, for this reason, I found it better to use the perlite for Hepatica potting/sowing mix.For growing alpine species, a mix from vermiculite & perlite (and some soil) works perfect.
