3.99 fpr 5 seeds? Thats not good. Success rate for trident maple seeds is about 25%. Maple seeds need to be stratigied, can take about 3 months before it sprouts, if it ever does. Best way to go would be to buy some pre bonsai. There are 2 sellers on ebay. 1 seller sales 3 red japanese maples for $10, about 24"-36". there is another seller selling 7 tridents for $25. the seller of the japanese maples usually has the green leaf jap maple 4 for $10. Either of those would be better than going the seed route. Here are the links
