United Kingdom 
I brought 3 Eryngium big blue plans from an online plant supplier. They all seemed healthy and I have planted them in a well drained soil poor soil in a sunny position. One of the plants has flowered very well but the other 2 have no flowers as yet. There is plenty of foliage to the unflowered Eryngium. Would anybody advise me why only one has flowered as they all in the same soil condition and sun aspect. Thank youn

I suspect the others are just growing , getting roots down into the soil and settling down in the new spot
Still plenty of time to flower and if they dont will next year
