The plants sold are individual seedings. Every seedling might be different and none of these is from in-vitro propagation. Some are available in very small quantity only! While I just have less than 5 of certain kinds others are available in quantities of 10-20 at maximum.
A few might be re-released at some point from tissue culture propagation or might be re-crossed at a later date but the seedlings you can buy in this section are one-offs - individual seedlings that may all show individual characteristics when older.
Just check this section frequently in order not to miss an opportunity! Once the traffic light switches to "red" all seedlings in sellabale size are gone but there will be a few more after some more months. Once all of them are sold they will be taken from the website with the next update.
Most seedlings still have juvenile leaves but all the ones sold are healthy, well rooted, greenhouse grown and in good size so that they might soon switch to adult-type leaves. Most have leaves of at least 5-6 cm in length.
First come - first serve!
