Comparing the early vigor of some garlic varieties

[bower]

This year I have 5 different varieties in one bed, that I am mainly growing to multiply as a seed stock. At first I had forgotten what was there and I wondered why some rows were not coming on as quickly - but this morning I looked at my 'map' and then I took a pic to compare the size of the sprouts in different rows.

From front to back:
First two rows are Persian Star, third row is Chesnok Red. These are four years from bulbils, which increased in size very slowly but did quite well last year in the warm dry summer. I nearly gave up on Chesnok Red as the seed stock I purchased got smaller and smaller here, but I thought they may adapt better from bulbils grown here. Really proud to see them all coming and as big as the Persian Star, which I got from scapes from my friend's farm and are doing alright for her. I have a second small bed with ten of each of them, and they are also up and looking good. These purple stripes are my latest to mature garlics, which makes them a bit risky to decline in size in a poor year, but they are certainly up vigorously and early this time.
Row 4 and 5: Spanish Roja. I grew a lot of these last year, this time I have just enough to preserve seed for the future. They are certainly the latest to come up. Last year they matured soon after the porcelains but based on other years I think they need more warmth to mature in good time. I like the idea of having big bulbils from a rocambole for seed purposes, but their survivorship has been poor for me so far. Also a bit disappointed how quickly they lose flavor in cooking, which makes them more of a 'raw only' garlic. Still a very nice flavor on these.
Row 6: "Bonavista Fireball" - still not sure if this is a porcelain or a marbled purple stripe. Really pleased to see their shoots are even bigger than the porcelain Argentina just behind them in the last row. I think the earliness of Bonavista = Argentina = Music - earliest and most reliable.

In the second pic my main crop of porcelains, Music on the left and Argentina on the right. Music I grew out from bulbils and it just keeps getting bigger. Argentina came from my friend's farm. The first year Argentina was impressive as the earlier and bigger of the two, but the year after they seemed to converge on the same size and date. I'm not sure of the reason for that. They are overall so similar, without labels and maps it would be very hard to tell them apart.

Just for reference I'm tossing in a pic of Egyptian Onions and rhubarb in the same part of the garden, to show how far along they are at the same time (May first).
