It is said that performing archanai with vilva leaves brings prosperty. Can any one elaborate ?

If you read the puranas and the vratakalpa manjari, ever so many vratams, poojais and archanais, naivedyams, etc., are detailed and specific results "palan" for each is also given. These were texts written for a population which lacked the general scientific awareness that even the poorest hindu (dalit class) old, illiterate woman or man has today; those populations were utterly gullible on the one hand and modern (western) science had not permeated our society as much it does today. Hence all the stories of archanais/naivedyams/abhishekams and particular 'results' have to be taken with a pinch of salt.
Having said that the most common slokam regarding vilvam is :—
त्रिदळम् त्रिगुणाकारं त्रिनॆत्रं च त्रयायुधम् ।
त्रिजन्म पाप संहारं एकबिल्वं शिवार्पणम् ॥
த்ரிதளம் த்ரிகுணாகாரம் த்ரிநேத்ரம் ச த்ரயாயுதம் |
த்ரிஜந்ம பாப ஸம்ஹாரம் ஏகபில்வம் சிவார்பபணம் ||
It only states the one bilva leaf (consisting of three petals) if offered to Lord Siva, will destroy all the sins committed by the offerer during the just preceding three births/lives; there is no mention of prosperity. Secondly, bilva leaf is usually not used in temples other than those for Siva, though I have heard of some exceptions also.
