I am not knowledgeable in growth patterns but it looks like it will be smallish (the basils on others grow much longer this one sent out 1 1/2 to 2ft practically all bloom)

Silver dollar size blooms (can't remember if there was a scent but don't think so - I don't smell well most of the time anyhow). Blooms last forever and ever, fade a little near the end. Color is very pink in shady weather and can go almost to powder pink in high heat after a couple weeks. Doesn't seem to burn at all.

Light green new growth - not red.

No thorns to speak of - maybe three on entire bush.

Really healthy.

(I think the first three aren't far off actual size - it was small in most respects.)
