Right now (Feb, 2018) Mandonii is almost impossible to get, and the cost of a mature bulb is usually quite high -- over $240 each -- if you can even find one. Even the seeds are pricey: I paid $10 for each seed. The only place I could find either -- bulbs or seeds -- was on eBay, and the offering is scarce -- few and far between. The seeds I bought did grow, and after almost 3 years are getting big enough to expect a possible bud in the next year, I hope. So, if you really want Mandonii, expect to pay a premium price, and buy it as soon as it is offered. If one is offered, it sells immediately, so do not wait more than a moment or two. Either that, or DO wait -- probably at least a few more years until there are more of them on the market. Seeds are a little easier to get, but they will take 3 or more years to bloom. It is your gamble to decide whether mature bulbs will be on the market before your seeds get big enough to bloom. As for me, I took the gamble.
