These are 1 year old adenium seedlings. Of about 25 seedlings 2/3 have the upside down wine glass shape. These generally seem more vigorous. About one third has the cylindrical coke bottle shape. The coke bottle shapes also tend to have some red in the leaves. Can that be used to determine which species they are? Most of.the seed I got was for Arabicum type so im guessing the spherical caudex upside down wine hlass is arabicum? some of.the seed was just a mix of red flowered adenium . Thanks in advance
