Totally agree @susanhumphrey333 they are really different remind me of Batman :-) Nice choice and coordination @rachelbrooks bet that looks really nice :-) Thank you for the tags @brightcolours much appreciated :-)
I have the same petunia's and doing great but I didn't get any (black) ones in mine. I bought both types from Notcutts Garden Centre, Norwich, in a tray, and I have been just so very pleased with them. I used bagged sterol compost from our Local Recycling Centre and it's terrific. Plenty of water, fed with miracle grow or tomorite and they just romped away.
