Did you download the chart recently? The new version updated this morning is better.

scandens .. if you do not have a reptans or a scandens, you cannot breed a scandens.

to get a scandens you need to breed a reptans with a scandens or a scandens with a scandens.

i would suggest buying some seeds from the store.

if you cannot buy the seeds you need (the store features new seeds to sell you every 24 hrs i think) then you can mutate seeds if you are lucky to get a scandens. mutate a grass. it would be much cheaper to buy the seeds you need from the store though.

to see why reptans and scandens make scandens, play with the new spreadsheet (link below).
