Dear Mary Sue, from your list of seed I have to say that Melasphaerula ramosa is the worst weedy bulb it has been my misfortune to grow, seedlings pop up everywhere and grow at an unbelievable rate, it may be that it is not such a problem elsewhere but in this basically Medditeranean climate I would never recommend it to my worst enemy,hope this is helpful. I would be interested to hear if it is well behaved somewhere, Lyn Edwards Canberra AUs. approx. zone 8 USDA
