It's a bit early for them as yet - be patient.

Mine is just opening now - mind I live in North East England so this is their normal time.

I planted mine this year but not till May, they're not in flower yet, expecting them to flower probably end of August, so depends when you put them in the ground too.

I had 3 this year and hopefully will have more next year, but mine have just finished flowering after opening in June.
